AM5728: How to use eth1 instead of eth0 in AM5728 Uboot

Hanc

Part Number: AM5728

The BSP I use is "PROCESSOR-SDK-LINUX-AM57X 06_03_00_106", I now want to implement tftp under uboot to load zImage on the server, but when I try to ping Ubuntu, uboot will automatically select the eth0 (RGMII0) network card, but we The product only leads to eth1 (RGMII1), how can I modify it in uboot to switch to the eth1 network card of AM5728

Thank you

Hi,

Can you try:

setenv ethact eth1

See if that helps your case? If yes do resolve the issue.

Hi,Keerthy

I set the environment variable "ethact" according to your suggestion, but it has no effect, uboot shows as follows

=> print ethact
ethact=eth1
=> ping 192.168.1.111

Hi Xiao,

Can you share the complete logs? Also the eth0 and eth1 dts instances in u-boot that you have added?

Xiao,

In case of u-boot in case an IP like cpsw having 2 ports there is no way to switch between eth0 and eth1. Its a framework limitation.
Just in case if that is indeed the case we are seeing eth1 cannot be used.

Keerthy
