Sorry for the long delay due to christmas vacation.


Do you know which PHY is used on?mx6cuboxi?

I am wondering if the ANATOP clock setting is correct (25MHz)?

http://git.denx.de/?p=u-boot.git;a=blob;f=board/solidrun/mx6cuboxi/mx6c
uboxi.c;h=fc37f1eef06da5147e5403d4272d220836c9cfbc;hb=HEAD#l167

Does it help to increase the delay and set it to 15ms?

Best regards
