Hi,
i am using k2 evm, i have downloaded K2 linux kernel earlier(almost 1 month back) 3.8.4 arago git and it woked fine on evm. note i have changed the start address to 0xA0000000.
rececntly i have tried to upgraded to latest "K2_LINUX_03.10.10_13.10_00" but it has multiple problems as mentioned below.
1) tcp checksum is wrong , thus i cannot boot with nfs root. to overcome i have commented out the h/w checksum offload in k2 dts. with this kernel is able to communicate with nfs server but immediately it crashes with below trace.
