I am using SEED's DM6446 EVM board,and i run the mv4.01 with 2.6.10 kernel from SEED DVSDK_1_20. Everything is running well.
but I down the DVSDK2.0 and mv5.0 form the TI site，I can't mount the root file system from my server(The error message in the bottom , ip is set static).
If I boot back the 2.6.10 , with the exactly same hardware and cables setup,(USE ip = dhcp, not try it with static ip) I could mount the root nfs. So definitely something changed in the 2.6.18.
I tried pinging - the pings work fine to several local hosts, also the kernel load via TFTP works fine, however the mount stage fails。
Following is the entire output messages:
