I have a problem with our new developed LS1021a board. There are three ethernet PHYs connected to LS1021a. Two PHYs are connected via RGMII with the PHY-Adresses 1 and 3.
We use LS1021A-IOT board as a reference board. We changed the RCW :
EC1=000 and EC2=000.
How should we modify U-boot configuration and Device Tree in order to ping the server from our board?
