CPSW PHY KSZ8041 ALIGN/CODE ERROR

Hi,peaves

You got it,it is the clock.

I disable the PLL clock ,select the chip pin ,and it works OK.

Thank you

Hi Yan,

I was reading your post above; I am currently in the same problem using Micrel KSZ8081RNACA chip for ether net with two ports
and chip seems to be not responding; I made various setting in the dtb/dbs tree or even at uboot level adjusting cpws structure, all avail.
Following is details log from kernel and device tree settings.
I will be grateful if you please observe and give your first hand opinion what is wrong?
Thank you,
