Add support for the F7008-2.5 board (PCB F7008-2.5GPOE-V1.2), an RTL8373N + RTL8224N design with eight 2.5GBASE-T ports and one SFP+ cage. The LED pads are not wired in port order, so the generic DEFAULT_8C_1SFP target lights the wrong lamp on this board. The pad to lamp map was measured on the hardware and is documented in doc/devices/F7008-2.5.md. The green lamp marks a 2.5G link, the yellow lamp blinks while data flows.

# F7008-2.5

| Guangnianwei (光年微) | 7018-2.5G | No | F7008-2.5GPOE-V1.2 | W25Q64JVSSIQ | 8373N + 8224N |
|
|
|
|
### What works
|
|
|
|
- All eight 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps
|
|
- SFP+ port with 1G/2.5G/10G modules
|
|
- LEDs of the eight RJ45 ports
|
|
|
|
### 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
|
|
the console to life.
|
|
|
|
### Build target
|
|
|
|
```
|
|
make MACHINE=F7008_2_5
|
|
```
|
|
|
|
### LED wiring
|
|
|
|
Measured pad to lamp map (`led_mux` index -> lamp):
|
|
|
|
| Port | green lamp | yellow lamp |
|
|
|------|-----------|-------------|
|
|
| 1 | pad 0 | pad 1 |
|
|
| 2 | pad 2 | pad 3 |
|
|
| 3 | pad 4 | pad 5 |
|
|
| 4 | pad 6 | pad 8 |
|
|
| 5 | pad 9 | pad 10 |
|
|
| 6 | pad 12 | pad 15 |
|
|
| 7 | pad 18 | pad 21 |
|
|
| 8 | pad 24 | pad 25 |
|
|
|
|
Pads 7, 11, 13, 14, 16, 17, 19, 20, 22, 23, 26 and 27 do not drive an RJ45 lamp.
|
|
|
|
The front panel is silkscreened `2.5G: Green / 10/100M: Yellow`, and the target
|
|
follows it: the green lamp is on while the port is linked at 2.5G, the yellow
|
|
lamp blinks while data is flowing.
|
|
|
|
