Hi all, 

 

I'am integrating ksz8863  to our customer board, based on  yocto linux-4.1.15-2.0.1 , 

now the fec is working correctly on linux, 3 ports work well  on RMII mode,  ( on u-boot-2016.03 alsa worked with port1 ),

 the only issues is that port2 (switch port) of ksz8863 is unable to notification imx6dl the network is became ready.

 

we must plugin cable to port1 of ksz8863 to activity the fec(ksz8863) , then 3 ports do data communication well,

 

ksz8863 port2 is able to notify imx6 that network is ready, because we have mx53 platform based on linux-2.6  that achieve this funciton, on mx53 platform, both ports of ksz8863 can notify CPU and to activity PHY 0:1 fec

 

it seems data report from port2(i guess have diffreenct id  ) to imx6dl is ignored....

 

is there somebody who know how to fix this?

 

Thanks in advance!!

 

Best regards!
