is it possible to use the second port of the AM62x Ethwernet switch in U-Boot ? It seems that the driver does only support one port in U-Boot. In Linux both Ethernet ports are working fine on our custom AM625x design.
The 2nd Ethernet port (RGMII2 pins) is visible in the U-Boot but it does not work. We need it in our product for firmware updates using TFTP.
Steps to repro:
1. Activate cpsw_port2 in the U-Boot DTS 2. The 2nd port is visible using U-Boot command "net list" (you see eth1) 3. Select the 2nd port with U-Boot command "setenv ethact eth1" 4. Use U-Boot ping or tftp and measure RGMII2_TXC (clock) with a scope: the pin does not toggle 5. No RGMII2 Tx pin moves at all even though they are all configured right.
