Hi,

I'm working on sama5d36 evaluation kit. From u-boot, I have set mac, ip. When I try to ping a ip address on LAN. I get "TX timeout". I can ping the ip successful with gmac0, but couldn't with macb0. Did anyone find this issue before?

Log: U-Boot> ping 192.168.10.11 macb0: PHY present at 0 macb0: Starting autonegotiation... macb0: Autonegotiation complete macb0: link up, 100Mbps full-duplex (lpa: 0xcd81) Using macb0 device macb0: TX timeout macb0: TX timeout ping failed; host 192.168.10.11 is not alive U-Boot> ping 192.168.10.11 macb0: PHY present at 0 macb0:0 is connected to macb0.
