machine_custom_init() runs once at boot, but its code and any tables it
uses were compiled into machine.c and so into the common bank. On the
SWTG018AS-V2.1.0 variant, whose init carries a 21-entry LED register
table, that overflows bank 0 by 0x66 bytes and main no longer links for
MACHINE_PCB_SWTG018AS_V2_1_0; any machine whose init grows can hit the
same wall. SDCC segment pragmas apply file-wide, so the hooks move to a
new machine_init.c compiled into BANK2, and the prototype becomes
banked. machine_check also compiles the new file per machine so the
hooks keep CI syntax coverage.
The SWTGW218AS label covers more than one PCB. On boards with the
SWTG018AS-V2.1.0 silkscreen the SFP module-detect is GPIO38 (no LOS pin
wired) and the LED block is wired differently, including a bi-color SFP
LED (green up to 2.5G, blue at 10G) that the LED-set encoding cannot
express. With the existing MACHINE_SWTGW218AS definition these boards
never detect an SFP module, so an SFP-uplinked switch comes up with no
working uplink.
Add the variant as its own machine define named by the PCB marking,
leaving MACHINE_SWTGW218AS unchanged for boards that match its wiring.
The LED register values are taken from the stock firmware; the PIN_MUX_0
write routes the blue-LED pin to the LED controller, without which no
LED register value can drive it. PIN_MUX_1/2 stay untouched so SFP
detect and i2c remain GPIOs.
Adds an optional per-board mac_flash_offset. When non-zero, RTLPlayground
reads a 6-byte MAC from that flash address and uses it if it is a valid
globally-administered unicast address; otherwise it falls back to the
generated locally-administered MAC. Offset 0 (default for every board)
preserves current behaviour.
Enable it for the SWTGW218AS, whose stock firmware keeps the factory MAC
in nvcfg at 0x1FC000. RTLPlayground images and web upgrades only touch
flash below that region, so the factory MAC survives flashing.

* fix(machine): update SFP port LED color descriptions for PCB-SWTG024AS V2.0
* add(doc): create a simple documentation for SWTG024AS-A-V2.0.1_5_RJ45
* refactor(machine): update machine definition
The ZX310S-4T2XT is a managed device with 2x2.5GBit and 2x10GBit Ethernet.
It is sold, among others, by Horaco as an unbranded device.
CPU: RTL8372
Flash: 2MByte Winbond W25Q16DV (U3)
PHY 2x RTL8261BE
While testing #246, I noticd that SFP did not light-up while forcing
2.5gbit link. This is because RJ45 and SFP share the same LED-settings.
But RJ45 has two leds-settings.
Solution is to add settings for SFP for both managed and unmanaged
variant.
I recently brought a "Ztyuav Z-QWYT0402", the insides looked identical to the
existing supported "Hisource Hi-K0402WS". Both of them have the
"PCB-K0402-V3.0" silkscreen.
I flashed the vanilla image and it seems to work great.
I changed the documentation to be more inclusive of other devices (including
adding a picture of mine). I suspect more devices might fall into this
"PCB-K0402-V3.0" bucket, for example the "YuanLey YS25-0402" with
the vlan switch also looks suspiciously identical from the outside.
I also added some details I noticed while flashing mine:
teardown, flash padding, how the selector switch actually works.
- machine.c/h: add MACHINE_FNS1200P with verified GPIO assignments for
both SFP ports, LED SET0 (amber 2.5G / green 1G-100M-10M) and SET1
(SFP all-speeds), led_mux from original firmware register dump, and
machine_custom_init() enabling LED_GLB_IO_EN bit 6
- doc/devices/FNS-1200P.md: device overview, port layout, serial
console (S1 three through-holes = UART0 115200 8N1 3.3V),
LED and SFP GPIO tables
- doc/devices/photos/FNS-1200P/: chassis front panel and PCB top photos
- doc/supported_devices.md: add FNS-1200P to the list
GPIO assignments and LED register values were cross-checked between
live GPIO observation (RTLPlayground gpio command) and an original
firmware register dump.
Add support for the ZX310S-4T2XH switch, which is a 4x2.5GBit + 1x10GBit + SFP
device. The device does not have any branding and is sold under different
brand names, in particular by Horaco. There is no branding on either label
nor PCB.
CPU: RTL8372
Flash: 2MByte Winbond W25Q16DV
10GBit PHY: RTL8261BE
UART header present, but solder holes are filled with solder that needs
removal, first, e.g with a 1.2mm drill.
The original firmware uses 57600baud 8N1
This splits the current MACHINE_KP_9000_9XHML_X definition into "V2_2"
and "V3_1" versions for the two known versions of this hardware.
Confirmed to work:
- LED configuration matches stock firmware
- Port ordering matches label
- A SFP can be detected and EEPROM read (I don't have a fiber cable to test link)
- Reset button presses are detected
It seems very likely that other versions are not compatible, so make it
clear by including it in the machine type and name. Also update the
documentation.
This board appears for example in the Davuaz Da-K6501W switch, and is
designed similarly to Hi-K0402WS.
However, it only has one SFP port and another 2.5G copper port using
RTL8221B 2.5G PHY instead. Also, some components on the board, like
additional LEDs, mode switch, and second flash chip are not populated.
Like earlier revisions of the K0402W(S) board, there is no UART, so
debugging is limited.
As this is an unmanaged switch, installation needs a flash programmer.
Looks like the SFP numbers are reversed, since GPIOs were mapped
to SFP numbers, the need to be reversed too. This fixes swapped
display of SFP stats on the webpage.
Added support for all leds on the device.
Stock port sets are slightly differently configured, where additional
LED0 on SET_0 and LED1&LED2 where configured for link/collisions/duplex.
This has not been reproduced as those lines are probably not connected
anywhere.
The SWTG018AS-A V2.0 is an 8x2.5GBit/s port + 1 SFP+ port unmanged device
It is sold in an unbranded casing e.g. by Ampcom.
Hardware:
SoC: RTL8373N
Additional PHY: RTL8224
Flash: Puya P25D40SH (4MBit, slimmer, not standard SOP-8 package!)
LEDs: 1 Green + 1 Orange per Ethernet port (green designates 2.5GBit)
1 Green LED for the SFP+ port
The photos already show a modified PCB: Unpopulated resistors R52 and R53
have been bridged in order to enable the serial console. The smaller flash
memory chip at U2 has been replaced with a Windbond 128MBit standard-sized
SOIC-8 chip in order to easily use SOIC clamps to flash the device. Also
the serial header has been populated.
