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?
have you checked your errata notice [1] in chapter 7.1.1? If you have a rev C base board you should add the impedance mismatch fix mentioned there.
Best regards
