Ethernet does not work

alexxowo

Hi everyone,
I recently compile the linux SDK for Firefly ROC3566-PC, to use an UART ports (3, 5 and 9), but, the ethernet port does not work... I see the driver in the sdk for realtek rtl8211f chip, on

rk356x_linux_release_20211019/kernel/drivers/net/phy/realtek.c

. I'm using Ubuntu 20.04 rootfs
When i use the precompiled image for  ubuntu given from FireFly team, i dont see drivers loaded with lsmod, so, i can't understand what's happen with this...

the gmac is okay in dts files.

use firefly firmware to make sure the hardware is OK
and 3566-pc using gmac1 m0 group pins, and thi ...

Oh, nice... When i use the firefly firmware, the ethernet port is up, but, with my firmware does not up.
This is my rk3566-firefly-roc-pc.dts file, i only removed the uart3 from this... And the ethernet is worked again, thanks you

1. &uart3 {
   
2.    status = "okay";
   
3. };
   
4. // i just removed the uart3, and it works.
   
5. &uart5 {
   
6.     status = "okay";
   
7. };
   
8. 
   
9. &uart9 {
   
10.     status = "okay";
    
11. };

Copy the code

but, i see in the ROC Rk3566-PC, in the J1 terminal, i only have an uart3_m0 for tx and rx, if i use uart3_m1, this port is not work for me in the J1 terminal, right?
