Hi Romain,
I assume this patch is meant to fix an ethernet issue in u-boot? How does
someone test that ethernet is working from u-boot?
Here is my firefly booting with these patches:
U-Boot SPL 2017.05 (Jun 17 2017 - 17:12:20)
Returning to boot ROM...
U-Boot 2017.05 (Jun 17 2017 - 17:12:20 -0400)
Model: Firefly-RK3288
DRAM: 1.7 GiB
MMC: dwmmc@ff0c0000: 1, dwmmc@ff0f0000: 0
*** Warning - bad CRC, using default environment
In: serial
Out: serial
Err: serial
Net:
Warning: ethernet@ff290000 (eth0) using random MAC address -
5a:40:1a:28:0e:43
eth0: ethernet@ff290000
Hit any key to stop autoboot: 0
Here is me configuring the networking stuff in u-boot:
=> setenv ipaddr 192.168.142.20
=> setenv netmask 255.255.255.0
=> setenv serverip 192.168.142.1
Then I try pinging my server:
=> ping 192.168.142.1
ethernet@ff290000 Waiting for PHY auto negotiation to complete... done
Speed: 100, full duplex
Using ethernet@ff290000 device
The next thing I know my firefly is rebooting:
