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.
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.
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.
