-## [0.x] - 2026-xx-XX
-
-## Added
-
-- Devices
-  - Support the hongyavision HYWS-SGT0204S (PCB marking `2G5F4_10G2_V1.01`), an
-    RTL8372 based 4x2.5G + 2xSFP+ unmanaged switch with a 512 KB Bright Moon
-    `T25S40` flash. It is a sibling of the KP-9000-6XH-X2 (2M-PCB43-V1.1) with
-    the two SFP+ cages wired the other way round (physical 5 is on SDS1,
-    physical 6 on SDS0), no reset button fitted, wrong silkscreen labels on the
-    serial header, `LED_GLB_IO_EN` bit 6 has to be set for the port LEDs to
-    work, and the fitted T25S40 cannot be read in DIO mode on this board, so the
-    target selects single-IO flash reads (`flash_sio`). New machine target
-    `MACHINE_2G5F4_10G2_V1_01`, see `doc/devices/2G5F4_10G2_V1.01.md`.
-
-- Web UI
-  - Compress the embedded assets (minify + gzip) and switch to a single-page layout. #315
-  - Replace the multi-page UI with a themed single-page app: light, dark and Selenized themes following the browser by default,
-    English, Japanese and Chinese, save to flash merges the command log into the startup config and verifies the write,
-    firmware images are checked in the browser before upload. #429
-
-## Changed
-
-## Fixed
-
-- Web UI
-  - Accept firmware uploads regardless of the file part's MIME type, including
-    `application/macbinary` sent by Chrome on macOS for `.bin` files.
-
-- Health
-  - `HEALTH=1` builds no longer write past the phase timing arrays at the LLDP checkpoint, which
-    corrupted the `link` slow counter and the DHCP client state. #658
-- Config
-  - A startup configuration line longer than the command buffer no longer stops the replay:
-    the offending line is skipped and the following lines are still applied.
-  - The web UI and the configuration upload now refuse a line the replay cannot take,
-    instead of writing it to flash.
-
-## Breaking changes
-
-- Config
-  - VLAN don't accept port `u`-suffix anymore.
-    So `vlan 1 4u` is not valid anymore.
-    Replace it with `vlan 1 4`.
-- Commands
-  - port zero/`0` is treated as the `CPU_PORT`. #326
-  - Many commands don't accept the CPU_PORT anymore. See #334.
-    When the CPU_PORT is needed, the command/service will add the CPU_PORT automaticly.
-    Only `isolate` accept the CPU_PORT as destination port.

-## [v0.1_aplha] - 2025-11-03

+## Compiling
 Install the following particular build requisites (Debian 12/13), note that Ubuntu 24.04
 still has an older version of sdcc, but you will need sdcc version 4.5 for the code to compile:
 ```
-sudo apt install make gcc sdcc xxd python-is-python3 libjson-c-dev zlib1g-dev
+sudo apt install make gcc sdcc xxd python-is-python3 libjson-c-dev
 ```

-<details>
-<summary>If using Docker (click to expand)</summary>
-
-### Prerequisites
-
-Install Docker for your platform:
-
-- **Linux (Debian/Ubuntu)**: `sudo apt install docker.io` then `sudo usermod -aG docker $USER` (log out and back in)
-- **Linux (other distros)**: Follow the [Docker Engine install guide](https://docs.docker.com/engine/install/)
-- **Windows**: Install [Docker Desktop for Windows](https://docs.docker.com/desktop/setup/install/windows-install/)
-- **macOS**: Install [Docker Desktop for Mac](https://docs.docker.com/desktop/setup/install/mac-install/)
-
-### Usage
-
-A Dockerfile is provided for a reproducible build environment:
-
+Edit machine.h with an editor like vi or nano. Select the correct machine the firmware should build for.
+Now, building the firmware image should work:
 ```
-docker build -t rtlplayground-dev .
-```
-
-Build the firmware (replace MACHINE with your target, e.g. `DEFAULT_8C_1SFP`):
-
-```
-docker run --rm -v $(pwd):/workspace rtlplayground-dev make MACHINE=DEFAULT_8C_1SFP
-```
-
-The resulting `.bin` file appears in `output/` on your host.
-
-Build host tools only:

-
-Run the web-interface simulator locally:
-
-```
-docker run --rm -p 8080:8080 -v $(pwd):/workspace rtlplayground-dev \
-  tools/output/httpd_sim /workspace/html
-```
-
-Edit `config.txt` on your host, then re-run `make` — the
-source directory is mounted into the container, so changes take effect
-immediately. To build for a different machine, pass `MACHINE=<name>`, which
-selects `machine/<name>.c` (see [Adding a new device](doc/adding-a-device.md)).
-
-</details>
-
-## (1) Compiling for direct chip flashing AND upgrading an existing RTLPlayground running device
-
-Pass the machine that matches your device, for example:
-```
-make MACHINE=DEFAULT_8C_1SFP
-```
-The name selects the board definition `machine/<name>.c`; `make` without a
-`MACHINE` value stops with an error listing what is expected. If your board is
-not in the list yet, see [Adding a new device](doc/adding-a-device.md).
-
-> [!TIP]
-> You can write configuration parameters in config.txt (see below) in order your switch to get
-> straight at the first boot, a correct IP configuration.
-
-Now, building the firmware image should work.
-
-Note, that the image generated ends in .bin, not .img, in order to make IMSProg happy.
-
-image location is stored in `RTLPlayground/output/rtlplayground_version_machine.bin`
-for example
-```
-rtlplayground-v0.1.0-12c98ba-dirty-LIANGUO_ZX_SWTGW215AS.bin
-```
-
-> [!CAUTION]
-> This image can be flashed directly to the chip OR through the firmware update/upgrade
-> interface of RTLPlayground interface
-
-## (2) Compiling for OEM running device with management options (web upgrade)
-
-Managed switches can be updated from the existing original firmware using a SPECIFIC upgrade image.
-You first need to build the firmware for direct chip flashing : See below (1)
-
-Then
-
-```
-cd installer
 make 
 ```
-image location is stored in  `RTLPlayground/installer/output/rtlplayground_oem_upgrade.bin`
-
-> [!CAUTION]
-> This image must ONLY be used for original OEM firmware web interface firmware upgrade.
-> You do not need this image if you are already on RTLplayground firmware.
-> Unless you go back to the original OEM firmware, you would only flash this specific firmware
-> only once. Future upgrades of RTLPlayground will only need to follow (1)
-
-example of compilation console output
+Note, that the image generated ends in .bin, not .img, in order to make
+IMSProg happy.
 
+Managed switches can be updated from the existing original firmware using an upgrade image.
+In the `installer`folder of the source code you will need to run `make` which will build
+an image out of `rtlplayground.bin` built in the previous step:
 ```
 RTLPlayground/installer$ make
-mkdir -p output
+mkdir -p output/
 gcc updatebuilder.c -o output/updatebuilder
 sdas8051 -plosgff -o output/crtstart.rel crtstart.asm

+> [!CAUTION]
+> DO NOT UPLOAD THE UPGADE IMAGE UNLESS YOU CAN MAKE A BACKUP USING A SOIC CLAMP OF THE
+> ORIGINAL FIRMWARE!
 
-## (3) Sandbox Usage with Ghidra (optional)
-
+## Installation
 You can play with the image using ghidra or flash real Switch Hardware. For
-ghidra see this information about [Ghidra images](doc/ghidra.md).
-
-## (4) Installation through the Web interface (software way)
-
-Managed switches (OEM firmware of RTLplayground firmware) can be upgraded via the web interface.
-Unmanaged switch cannot be flashed this way (see 5).
-
-Go to "Firmware update" tab, select the correct file.
-
-> [!IMPORTANT]
-> If your device already runs RTLPlayground, you must upload the binary file /RTLPlayground/output/rtlplayground_Version_Machine.bin
-> If your device is OEM, you must upload the binary file /RTLPlayground/installer/output/rtlplayground_oem_upgrade.bin
+ghidra see this information about [Ghidra images](ghidra.md).
 
 > [!CAUTION]
-> Check one more time that your device matches the machine type before flashing.
-> Be sure you have a backup of the original firmware before diving in RTLPlayground.
+> NOTE THAT WHILE THIS PROCEDURE HAS BEEN SUCCESSFULLY TESTED ON ALL DEVICES ABOVE,
+> ABSOLUTELY NO GUARANTY CAN BE GIVEN THAT YOU WILL NOT DESTROY YOUR SWITCH,
+> ANY OTHER EQUIPMENT INVOLVED OR HARM YOURSELF BY OPENING THE ELECTRONIC
+> DEVICE. OPENING THE SWITCH WILL VOID ITS WARRANTY.
 
-Finally, push the Upload File Button and you're done !
+You can upload the upgrade image of managed switches via the web interface of the
+original firmware just as if you were installing a firmware upgrade. However,
+this is strongly discouraged, as you may brick your device, unless you can make
+firmware backups via a SOIC clamp or soldered flash socket, first!
 
+For unmanaged devices, the only way to install RTLPlayground is by flashing the
+Flash memory directly.
 
-## (5) Flashing the ROM directly (hardware way, but also only way to rescue)
+You will need to open your switch to flash the image directly onto the flash chip,
+which is done easiest using a SOIC-8 clip (alternatively you de-solder the
+flash chip and install a SOIC adapter):
+- Disconnect power from switch
+- Attach the clip onto the flash chip
+- Connect USB of flash programmer, the power LED on the switch will light
+  up, check cabling if not. Don't panic, mixing up GND and 3.3V does not
+  seem to destroy the switch (at leasts the on I did this to).
+- Use IMSProg (flashrom should work, too) to detect the clip
+- MAKE A BACKUP OF THE EXISTING FIRMWARE!
+- then load the firmware into IMSProg
+- and program flash
 
-This procedure is the only way to flash unmanaged switches, if the ROM chip is large enough.
-This is also the only way to unbrick your device if something went wrong.
+Now you can connect a serial cable to the UART port found on all the
+devices, set 8N1 @ 115200 baud and power up the switch.
 
-> [!IMPORTANT]
-> You need a SOIC-8 clip to flash the ROM chip directly onboard.
-> Alternatively you can de-solder the flash chip and install a SOIC adapter).
-> For flashing the chip directly, you must use the binary file /RTLPlayground/output/rtlplayground_Version_Machine.bin
+The device will perform some examples and provide a minimal console, the
+documentation of which can be found in the source code rtlplayground.c`.
 
-> [!CAUTION]
-> As you need to open your switch case, consider that the warranty is gone.
-
-- Disconnect power from switch.
-- Open the switch.
-- Attach the clip onto the flash chip (Red line on Pin 1, Pin 1 has a point marker).
-- Connect USB of flash programmer, the power LED on the switch will light up, check cabling if not.
-- Don't panic, mixing up GND and 3.3V usually does not destroy the switch.
-- Use IMSProg, Flashrom, or whatever Programmer to detect the chip.
-- MAKE A BACKUP (DUMP) OF THE EXISTING FIRMWARE !
-- ERASE THE ROM (BLANK) !
-- Load the firmware into IMSProg.
-- Flash is to the ROM chip.
-- Disconnect the clip from the ROM chip.
-- You're done, ready for the first boot.

-## (6) Connecting a serial interface (optional)
-
-You can connect a serial cable to the UART port found on all the devices, set 8N1 @ 115200 baud.
-
-## (7) Power Up
-
-When you power up the switch, the device will perform some examples and provide a minimal console
-(if wired to a serial interface), the documentation of which can be found in the source code rtlplayground.c`.
-
-## (8) The web-interface
-
-The web-interface can be reached under the [default 192.168.10.247](http://192.168.10.247) unless you
-specified an IP address in the config.txt before compilation.
-
-> [!TIP]
-> The default password is `1234`.

-# Adding a new device
-
-A device is supported by adding one board header `.h` and board definition `.c` file
-under `machine/`. 
-the build selects the definition by name, and CI compiles every file it finds.
-
-To compile for your added device, do:
-```
-make MACHINE=<NAME>
-```
-
-## What a new device consists of
-
-| File | Purpose |
-|------|---------|
-| `machine/<NAME>.c` | the `struct machine machine` board definition |
-| `machine/<NAME>.h` | `MACHINE_MODEL` (the model string shown in the UI and the CLI) and `MACHINE_CHIPSET` (`RTL8372` or `RTL8373`) |
-| `machine/<NAME>_init.c` | optional `machine_custom_init()` boot hook, for registers the machine definition cannot express |
-| `doc/devices/<name>.md` + `doc/supported_devices.md` | (only if the board is verified and you want to support it publicly) user-facing documentation |
-
-`<NAME>` is the machine symbol without its `MACHINE_` prefix, so `MACHINE` is
-passed exactly as spelled on the command line: `make MACHINE=MY_BOARD_1_0`
-needs `machine/MY_BOARD_1_0.c` and `machine/MY_BOARD_1_0.h`.
-
-## Step 1: the board header
-
-`machine/<NAME>.h` carries the product string and the SoC family. Use the
-existing files as the template:
-
-```c
-#ifndef _MACHINE_MY_BOARD_1_0_H_
-#define _MACHINE_MY_BOARD_1_0_H_
-
-#define MACHINE_MODEL "Brand Model V1.0"
-#define MACHINE_CHIPSET RTL8373
-
-#endif
-```
-
-`MACHINE_CHIPSET` is `RTL8373` or `RTL8372`; a build without it will fail. It selects the default
-logical port range: `MACHINE_MIN_PORT` is `0` for RTL8373 and `3` for RTL8372, while
-`MACHINE_MAX_PORT` is `8`, the highest logical port index. A board with a different range defines
-`MACHINE_MIN_PORT` and/or `MACHINE_MAX_PORT` in its header to override the
-defaults.
-
-The device product string is what the CLI or the Web-Interface will print to identify the device; `machine.h` includes it by name.
-
-> [!NOTE]
-> `machine_name` is a `char[30]` and `MACHINE_MODEL` is copied into it at
-> compile time. A longer model string still builds, but SDCC emits
-> `warning 147: excess elements in array of chars initializer` and the name is
-> truncated in the UI. Keep it to 29 characters or less.
-
-## Step 2: the board definition
-
-`machine/<NAME>.c` starts with the shared prelude and then defines the single
-`machine` object. Copy the closest existing board and adjust it — do not start
-from a blank file, the field meanings are easier to see in a real example.
-The best choice is usually a device that has the same number and type of Ethernet
-ports and the same number of SFP+ cages.
-
-```c
-#include "machine_defs.h"
-
-__code const struct machine machine = {
-	MACHINE_COMMON_SETTING,
-	.n_sfp = 1,
-	.log_to_phys_port = {1, 2, 3, 4, 5, 6, 7, 8, 9},
-	.phys_to_log_port = {0, 1, 2, 3, 4, 5, 6, 7, 8},
-	.is_sfp = {0, 0, 0, 0, 0, 0, 0, 0, 1},
-
-	.sfp_port[0].pin_detect = GPIO30_ACL_BIT3_EN,
-	.sfp_port[0].pin_los = GPIO37,
-	.sfp_port[0].pin_tx_disable = GPIO_NA,
-	.sfp_port[0].sds = 1,
-	.sfp_port[0].i2c = I2CBUS( GPIO39_I2C_SDA4, GPIO40_I2C_SCL3_MDC1 ),
-	.reset_pin = GPIO_NA,
-
-	.high_leds = { .mux = LED_27 | LED_29, .enable = LED_28_SYS | LED_29 },
-	.port_led_set = { 0, 0, 0, 0, 0, 0, 0, 0, 1 },
-	.led_sets = {
-		{   /* RJ45 ports */
-			LEDS_2G5 | LEDS_LINK,
-			LEDS_2G5 | LEDS_1G | LEDS_100M | LEDS_10M | LEDS_LINK | LEDS_ACT,
-			0,
-			0
-		}, { /* SFP port, single green LED */
-			LEDS_10G | LEDS_2G5 | LEDS_1G | LEDS_100M | LEDS_10M | LEDS_LINK | LEDS_ACT,
-			0,
-			0,
-			0
-		}
-	},
-};
-```
-
-`MACHINE_COMMON_SETTING` (from `machine_defs.h`) initializes `machine_name` and
-`isRTL8373` from the header's `MACHINE_MODEL` and `MACHINE_CHIPSET`. The logical
-port range comes from `MACHINE_MIN_PORT` and `MACHINE_MAX_PORT` in `machine.h`.
-Keep it as the first initializer and list the board-specific fields after it.
-
-### Fields
-
-| Field | Meaning |
-|-------|---------|
-| `MACHINE_COMMON_SETTING` | expands to `machine_name` (`MACHINE_MODEL`) and `isRTL8373` (`1` for `RTL8373`, `0` for `RTL8372`); both are derived from the header's `MACHINE_CHIPSET` (see Step 1) |
-| `n_sfp` | number of SFP+ cages |
-| `n_10g` | SerDes 10G capability used by the RTL837xN init: `0` none, `1` one, `2` two 10G-capable SerDes |
-| `log_to_phys_port[9]` | logical port (0-based index) → physical front-panel port number |
-| `phys_to_log_port[9]` | the inverse, physical port 1 is index 0, unused slots are 0 |
-| `is_sfp[9]` | `0` for copper, `1` for left slot and `2` for right slot |
-| `sfp_port[2]` | per-cage wiring, `sfp_port[0]` is the leftmost cage |
-| `reset_pin` | GPIO of the reset button, `GPIO_NA` if unpopulated |
-| `high_leds` | mux/enable for the LED pins 27–29 (`LED_27`, `LED_28_SYS`, `LED_29`) |
-| `port_led_set[9]` | which LED set (0–3) each logical port uses |
-| `led_sets[4][4]` | Each port can have up to 4 GPIO output pins assigned. 4 sets of LEDs with 4 LED-conditions per set; the conditions define which GPIO pins become active for a port given a port link-state. Which LEDs are then enabled depends on the wiring of the pins to up to 3 LEDs for that port, which can make a logical combination of the 4 LED output-pins. |
-| `led_mux_custom` / `led_mux[28]` | `1` plus the 28 mux values when the stock LED muxing does not fit the board |
-| `mac_flash_offset` | flash offset of the factory MAC address, omit or `0` if the board does not store one |
-
-Each `struct sfp_port` entry holds `pin_detect`, `pin_los`, `pin_tx_disable`,
-`sds` (which SerDes drives the cage) and `i2c` (built with `I2CBUS(sda, scl)`,
-or `GPIO_NA`-based values where a cage has no such pin).
-
-`I2CBUS(...)` only accepts the pin pairs listed in `machine_defs.h`. A wrong
-pair is caught at compile time: SDCC reports
-`error 176: sizeof applied to an incomplete type` pointing at the offending
-`.i2c` line, because the macro deliberately turns an invalid bus number into an
-array of size 0.
-
-### Reusing an existing definition
-
-If the new board is electrically identical to one that already exists — same
-port mapping, same SFP wiring, same LEDs — do not copy the file. Make the new
-`.c` a symlink and keep only a distinct `.h`, so the two boards cannot drift
-apart:
-
-```
-ln -s KP_9000_6XHML_X2.c machine/MY_BOARD_1_0.c
-```
-
-The new board still needs `machine/MY_BOARD_1_0.h` (pick the version number on
-the PCB) with its own `MACHINE_MODEL` and `MACHINE_CHIPSET`: `MACHINE_MODEL` is
-what distinguishes the products, and `MACHINE_CHIPSET` must match the SoC of
-the board definition being reused.
-Existing examples: `machine/PCB_K0402WS_V3.c`, `machine/KP_9000_9XHML_X_V3_2.c`
-and the six `KP_9000_*` revision variants.
-
-Two files that differ only in whitespace or comments are duplicates and should
-be collapsed this way.
-
-### Optional custom init hook
-
-If the board needs custom initialization, add
-`machine/<NAME>_init.c` defining `machine_custom_init()`. The Makefile picks the
-file up by name and compiles it.
-
-Boards that need the same hook share one file: keep the code in a single
-`machine/<NAME>_init.c` whose `machine/<NAME>.c` is a real file (not a symlink),
-and make the other boards' `_init.c` symlinks to it, for example:
-
-```
-ln -s KP_9000_6XH_X2_init.c machine/MY_BOARD_1_0_init.c
-```
-
-## Step 3: build and verify
-
-```
-make MACHINE=MY_BOARD_1_0
-```
-
-The generated flash image appears as `output/rtlplayground-<version>-MY_BOARD_1_0.bin`. An
-unknown or empty `MACHINE` fails immediately with a message naming the expected
-file, before anything is compiled.
-
-Then run the checks CI runs:
-
-```
-make machine_check    # compiles machine/<NAME>.c and its optional _init.c for every machine
-make -C test          # host-side unit tests
-```
-
-`make machine_check` discovers the definitions with
-`$(wildcard machine/*.c)`, so a new file is covered without registering it
-anywhere. CI (`.github/workflows/build.yml`) runs it on every push and pull
-request, alongside full builds for a 4+2 and an 8+1 board.
-
-A successful compile only proves the definition is syntactically valid. The
-actual behaviour — port numbering, SFP detection, LEDs — has to be confirmed on
-hardware, and the console commands (`port`, `stat`, `sfp`, `leds`) are the
-tools for that.
-
-## Step 4: documentation
-
-Once the board has been tested on hardware:
-
-1. Add a row to the table in [Supported devices](supported_devices.md).
-2. Add `doc/devices/<name>.md` describing the board, the build target
-   (`make MACHINE=MY_BOARD_1_0`), what works and what is unverified, plus
-   photos and the PCB silkscreen marking.
-3. If the board shares a PCB with other revisions, follow
-   `doc/devices/KP-9000-6XH-X2.md` and document which `MACHINE` to pick for
-   which silkscreen.
-
-### Identifying the CPU variant
-
-For RTL8373-based devices, use the read-only console command below to distinguish
-the N and non-N CPU variants:
-
-```text
-regget 4
-```
-
-| Register 0x0004 value | CPU |
-|---|---|
-| `0x83730000` | RTL8373 (non-N) |
-| `0x83737000` | RTL8373N |
-
-Record the identified CPU in the device documentation. These values identify
-only the CPU variant; document PHY and flash-chip models separately when verified.

-## Upload
-
-You can automate upload of the firmware via WEB with curl:
-
-1. Authorize with /login endpoint and save cookie:
-
-   ```bash
-   curl -c cookies.txt  http://${SWITCH_IP}/login -d pwd=${PASSWORD} -i
-   ```
-
-   This will save session cookie in cookies.txt
-2. Send the firmware via form:
-
-    ```bash
-    curl -b cookies.txt http://${SWITCH_IP}/upload -F "uploadedfile=@${FIRMWARE_FILE_PATH}" -i
-    ```
-
-    You can expect that server will close connection, without responding to request.
-    Wait for SWITCH_IP to be responding again.
-
-## Port status
-
-In similar way to upload, you can fetch the json status of the ports.
-
-1. Get the session cookie as for upload.
-2. Hit the `/status.json` with cookie:
-
-    ```bash
-    curl -b cookies.txt http://${SWITCH_IP}/status.json
-    ```

-RTL8372-based 4×2.5G + 2×SFP+ unmanaged switch.
-
-Also marked on the PCB as `2G5F4_10G2_V1.01`.
-
-Stock firmware runs a factory test console on UART at 9600 baud 8N1 (banner
-`RTL8371B start`, prompt `RTL8371B:`). There is no management CLI and no Web
-interface.
-
-Using SPI clamp in-board is the only method for initial installation and update.
-Erase the whole chip and verify the write (`flashrom -v`) before powering the
-board, so an incomplete write is caught before the board is powered up.
-
-Stock flash chip is 512 KB (Bright Moon `T25S40`, 4 Mbit, SOP-8), which the
-RTLPlayground image fills exactly.

-- **Manufacturer**: hongyavision (Shenzhen Hongyavision Electronic Technology
-  Co., Ltd.)
-- **Model**: HYWS-SGT0204S — the nameplate is printed in Chinese and reads
-  "10/100/1000/2500M fibre switch" and "4x 2.5G copper port + 2x 10G SFP+
-  optical port"
-- **Ports**:
-  - 4 × RJ45: 10/100/1000/2500 Mbps
-  - 2 × SFP+: 1G / 2.5G / 10G
-- **Power**: 12 V DC, 2 A
-- **Serial number**: `S/N-YYYYMMDDNNNN`, e.g. `S/N-202312010028`
-
-The top of the case only carries generic printing ("2.5G+10G High Speed Fiber
-Transceiver / 4-Port 2.5G Ethernet Switch+10G Fiber"), so the nameplate on the
-bottom is what identifies the device.
-
-### What works
-
-- All four 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps
-- Both SFP+ ports supporting 1G, 2.5G and 10G modules
-- Copper LEDs: white (2.5G) and blue (link/activity)
-- SFP LEDs: one single LED per port (link/activity)
-- SFP EEPROM and DDM readable on both cages, verified with a 10G module
-  (`Rate: 0x67`, module identity and DDM values via the `sfp` console command)
-- Serial console at 115200 8N1 (RTLPlayground) / 9600 8N1 (stock)
-
-### Not verified
-
-- The reset button footprint is unpopulated and the case has no opening for it,
-  so it could not be tested.

-**Board markings**
-- Top silkscreen: `2G5F4_10G2_V1.01`
-
-**Key components**
-- Main switch: RTL8372 (RTL8371B family), reported as `RTL8372` (non-N) by
-  RTLPlayground. The chip sits under a heatsink and its package marking is not
-  readable.
-- U1: SPI NOR flash, Bright Moon `T25S40`, 4 Mbit / 512 KB, SOP-8
-- A 3-hole reset button footprint is present but unpopulated, and the case has
-  no opening for it, so there is no usable reset button

-### Port layout
-
-| Front panel position | Logical port | Physical port | Type    |
-|----------------------|--------------|---------------|---------|
-| SFP left             | 8            | 5             | SFP+    |
-| RJ45 1               | 4            | 1             | Copper  |
-| RJ45 2               | 5            | 2             | Copper  |
-| RJ45 3               | 6            | 3             | Copper  |
-| RJ45 4               | 7            | 4             | Copper  |
-| SFP right            | 3            | 6             | SFP+    |
-
-Copper ports 1–4 match the KP-9000-6XH-X2 (2M-PCB43-V1.1) layout, which this
-board is a sibling of. The two SFP+ cages are wired the other way round
-compared to that board: physical port 5 is on SDS1 and physical port 6 is on
-SDS0.
-
-### Serial console
-
-The board has three through-holes used as the serial console, next to the
-heatsink in the middle of the board and visible in the top side photo above (the
-silkscreen labels are printed rotated by 90°). **The silkscreen labels are
-wrong**: they are shifted relative to the actual signals.
-
-| Silkscreen label | Actual signal |
-|------------------|---------------|
-| TX               | GND           |
-| RX               | TX            |
-| GND              | RX            |
-
-Wiring (following the measured signals, not the labels):
-
-| USB-TTL adapter | Board pad            |
-|-----------------|----------------------|
-| GND             | pad labelled `TX`    |
-| RX              | pad labelled `RX`    |
-| TX              | pad labelled `GND`   |
-
-- **Settings**: 115200 baud / 8N1 / 3.3V TTL (RTLPlayground), 9600 baud for the
-  stock firmware
-- The stock firmware only prints a few bytes and a factory test menu
-  (`?`, `rst`, `f`, `r`, `10`, `100`, `g1`, `sd`, `eye`, …); it is not an
-  interactive management console
-
-### LED configuration
-
-Case silkscreen, below the RJ45 ports:
-
-```
-White : 2.5G    Blue : 1000M/2500M L/A
-```
-
-The front panel also carries a `PWR` LED and one LED per SFP cage (`SFP1`,
-`SFP2`) on the right hand side.
-
-| Port       | LED          | Linked, idle | With traffic |
-|------------|--------------|--------------|--------------|
-| Copper     | white        | 2.5G only    | same         |
-| Copper     | blue         | solid        | blinks (L/A) |
-| SFP        | single LED   | solid        | blinks (L/A) |
-
-Measured LED-ID mapping (from the RTL837x LED set registers):
-
-| LED-ID | Function                        |
-|--------|---------------------------------|
-| LED-ID0| copper blue LED                 |
-| LED-ID1| copper white LED                |
-| LED-ID2| SFP single LED                  |
-
-**Important**: `RTL837X_REG_LED_GLB_IO_EN` bit 6 must be set in
-`machine_custom_init()`. Without it the RTL837x "solid" conditions (LINK/speed)
-do not drive the LEDs at all and only `ACT` does, which makes the white LED
-glow faintly at non-2.5G speeds.
-
-### SFP GPIO assignments
-
-| SFP               | pin\_detect (ModAbs)          | pin\_los         | SerDes | I2C SDA                 | I2C SCL                  |
-|-------------------|-------------------------------|------------------|--------|-------------------------|--------------------------|
-| Left (logical 8, physical 5) | GPIO30\_ACL\_BIT3\_EN | GPIO37   | SDS1   | GPIO39\_I2C\_SDA4       | GPIO40\_I2C\_SCL3\_MDC1  |
-| Right (logical 3, physical 6)| GPIO50\_I2C\_SCL2\_UART1\_TX | GPIO10\_LED10 | SDS0 | GPIO41\_I2C\_SDA3\_MDIO1 | GPIO40\_I2C\_SCL3\_MDC1 |
-
-`pin_tx_disable` is GPIO\_NA on both ports. Both I2C buses are confirmed
-working: with the same 10G module inserted, the `sfp` console command reads its
-vendor and model from the left cage (`Slot 1`) and from the right cage
-(`Slot 2`), DDM values included. The insertion also shows which SerDes drives
-each cage - the left cage reports `sds_config sds: 01` and the right cage
-`sds: 00`, which matches the table above.
-
-### Machine target
-
-Build for this device with `make MACHINE=2G5F4_10G2_V1_01`, which selects the
-`machine/2G5F4_10G2_V1_01.c` board definition. It is derived from
-`machine/KP_9000_6XHML_X2.c` with the SFP cage order and the reset pin changed.
-The fitted T25S40 cannot be read in DIO mode on this board: an image that leaves
-DIO enabled does not come up at all, both at the default read clock divider of 4
-and at 8 (two boards tested), while the same image with single-IO boots and runs
-normally. The board definition therefore sets `flash_sio`, which makes
-`flash_init()` use `CMD_FREAD` at divider 8. Only the management plane is
-slower, the ASIC keeps forwarding in hardware.

-
-## Compared to V3.1
-
-The component placement matches [2M-PCB23-V3.1](2M-PCB23-V3_1.md): same
-positions for the flash (U8), the T7/T8/T9/T10 headers, the SFP cage and its
-LED, and the unpopulated U7/U9 footprints. Build with
-`make MACHINE=KP_9000_9XHML_X_V3_2`, whose board file is a symlink to the V3.1
-definition and only differs in the reported name.
-
-## Tested
-
-Installed from the original firmware through its web interface with
-`installer/output/rtlplayground_oem_upgrade.bin`, then:
-
-- RJ45 ports link at 2.5G; LEDs: orange at 2.5G, green below
-- SFP port: module detected with vendor/model/serial and DOM readings
-  (temperature, Vcc, TX bias, TX/RX power), link up at 10G
-- factory MAC read from flash (0x1FC000)
-- reset button (GPIO48): held for more than 10 s it restores the default config
-
-## Flash access
-
-Reading the flash in-circuit with a SOIC-8 clip did not work: the chip ID
-comes back as `EF FF FF` (only the manufacturer byte is right) and reads
-return 0xff, the same as on a V3.1 board. The switch chip is powered through
-the clip and keeps driving the SPI lines. Make sure a way back is acceptable
-before installing, or hold the switch chip in reset while reading.

-> [!CAUTION]
-> This device operates on mains voltage, which can be a dangerous or potentially lethal hazard. Even after the device is unplugged, high-voltage capacitors can remain charged afterward and may still shock you. Do not attempt to open/disassemble a mains powered device unless you understand how to do so safely. Also, opening the device may void your warranty.
-
-## Notes
-
-The stock firmware blinks both the 2.5G and 1G LEDs on activity, despite the front of the device indicating that each LED should be independent. The `POE_2G080110GS` machine config behaves as the front of the device indicates (and what seems more logical) -- each port LED turns on and blinks independently.

-
-### Not verified
-
-- The LED pads for the SFP+ cage are not mapped yet. The SFP+ lamps are left
-  undriven, so an inserted module lights nothing.
-- The UART header footprint is present but unpopulated, and no boot log could be
-  captured from it, so the baud rate is unknown. There are most likely
-  unpopulated 0-Ohm resistors next to the header; bridging those should bring

-### Serial console
-
-The PCB has five unpopulated through-holes near the SoC, with a white rectangle surrouding them, labeled as `J18` and a triangle points to the square shaped first pin.
-
-This is where the "expected" UART header should be soldered at, with redundant 3V3 VCC, but also with missing 0Ω resistors between TX/RX and SoC, so simply soldering a header would not work. One need also add the missing resistors or solder the pads together, while making sure not connecting unrelated pads.
-
-Numbered from the triangle, the header pinout is:
-
-| Position | Signal | GPIO   | Status      |
-|----------|--------|--------|-------------|
-| 1        | GND    | GND    | Internal    |
-| 2        | TX     | GPIO31 | Unconnected |
-| 3        | RX     | GPIO32 | Unconnected |
-| 4        | 3V3    | -      | Internal    |
-| 5        | 3V3    | -      | Internal    |
-
-There're four resistor pads near the header.
-
-| Resistor ID | SoC Side    | Header Side |
-|-------------|-------------|-------------|
-| R1240       | TX / GPIO31 | Pin 2       |
-| R1243       | 3V3         | -           |
-| R1242       | 3V3         | Pin 3       |
-| R1241       | RX / GPIO32 | -           |
-
-To get TX working, solder a 0Ω resistor between the pads for R1240 or solder them together.
-
-For RX However, the designer certainly made a mistake, as the SoC-side lines to the resistor expected for Rx (R1242) and 3V3 (R1241) are swapped. For RX to work, the R1241 SoC side and R1242 header side shall be connected, so either:
-
-- Solder: R1241 SoC side -> R1241 header side -> R1242 header side
-- Jump wire: R1241 SoC side -> R1242 header side
-
-Be sure not to bring R1242 SoC side to the connection as that would wire Rx to 3v3.
-
-A complete working serial header should look like following on this PCB:

-
-### Machine configuration
-
-- `reset_pin`: GPIO54_ACL_BIT2_EN
-- High LEDs (pads 27-29): mux = `LED_27 | LED_28_SYS | LED_29`, enable = `LED_28_SYS | LED_29`
-
-### PoE
-
-The 8 copper ports support PoE powered by a DC 52V 2.5A input. Power management is handled by two HS104PTI chipsets over I2C (GPIO47_I2C_SDA0, GPIO46_I2C_SCL0):
-
-* Chip 1 (I2C address 0x1A): 2.5G Ports 1–4
-* Chip 2 (I2C address 0x2A): 2.5G Ports 5–8
-
-Note: The current implementation does not yet support PoE management. Consequently, PoE currently operates in standalone mode without software control.

-
-This board appears for example in the Davuaz Da-K6501W switch.
-
-The general design of the board is similar to Hi-K0402WS V3.0.
-However, there are several differences:
-- One SFP port is replaced by a RTL8221B 2.5G PHY
-- Only one LED is populated for the SFP port
-- No mode switch and only one flash chip
-- Older design using RTL8372 instead of RTL8372N (which also means different GPIO and LED configuration)
-- Like earlier versions of the K0402W(S) board, there is no UART
-
-All ports and LEDs are supported.
-Installation is possible using a flash programmer.
-The BoyaMicro 25Q16BSSIG flash chip is supported by flashprog with chip name "B.25D16AS/BY25Q16BS/BY25Q16ES".

-- **Console:** 115200 baud (RTLPlayground firmware) / 9600 baud (stock firmware)
-
-**Note:** These devices are **RTL8372N-based** with **LAN ports mounted upside-down on the PCB**, requiring a custom configuration. The `MACHINE_ONT_S207CW_62TS_SE` definition uses a **custom configuration** with:
-- Corrected port mapping (physical ports 1-4 = RJ45, 5-6 = SFP)
-- Optimized LED sets for different port wiring (RJ45 Ports 1-2 have reversed LED wiring)
-- Custom LED mux configuration

-GPIO assignments were verified by observing GPIO state changes during SFP module insertion/removal
-and cross-checked against an original firmware register dump.
-`pin_tx_disable` is GPIO\_NA on both ports (original firmware keeps all GPIOs as inputs).

-
-### Programming
-
-Using SPI clamp in-board is the only method for initial installation.
-
-The board has two flash chips `BY25Q16BS` with 16M-bit size. The front switch, switches between the two flash chips.
-These can be programed independently by using said switch - so it is e.g. possible to run the original and new firmware in parallel.
-The switch actually controls the HOLD line of each flash chip, and toggling the switch results in a reboot.
-
-If the programming clip keeps HOLD not connected, the flashing will commence on whatever the switch selected, regardless on which chip was clipped.
-
-For the initial flash (at least with flashrom), the bin file produced by the build is much smaller than the flash chip, it is suggested to pad the file to keep flashrom happy: `truncate -s 2097152 rtlplayground-*-PCB_K0402WS_V3.bin`. Note: do not then proceed to use this resulting padded file for the web flashing (as it bricks the device), use the original unpadded .bin.

-## Notes
-
-While [SWTG024AS.md](SWTG024AS.md) can be used as a general reference for hardware concepts and interface specifications, this device should not be assumed to be identical beside the difference implicitely highlighted below. Not all information has been validated for compatibility with the SWTG215AS. Consult the SWTG024AS documentation with caution and verify any critical details against this device's.
-
-## Flashing
-
-For devices with Winbond 25Q16JVSIQ, flashing is possible for example using flashprog with device "W25Q16.V". Note that you should not overwrite the whole flash to keep device-specific data (like the MAC address at 0x1fc000). Also, creating a backup of the entire falsh before is of course a very good idea.

-The original software is running UART on 57600 baud rate. The solder holes
-of the UART header are filled in. In order to install a UART header, they
-need to be cleared first. A 1.2mm drill can be used, alternatively a
-de-soldering wick.
-The original firmware uses 57600 baud 8N1
