Hello All,

 

I have been trying to boot the LS1021A-TWR board with Qoriq SDK v2.0 and been seeing this network driver crash there after the NFS boot hangs:

Could anyone confirm that network driver is working without any issues in Qoriq SDK v2.0 for Layerscape LS1021A board ?

 

Thanks in Advance!
