Thanks! > > Zhang This indicates that your bootloader ENV "bootargs" is missing the rootpath, nfshost and nfsroot values. I'm quoting from the Getting Started Guide (spruf73b): EVM # setenv nfshost <ip address of nfs host> EVM # setenv rootpath <directory to mount> EVM # setenv bootargs console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock mem=116M video=davincifb:vid0=720x576x16,2500K:vid1=720x576x16, 2500K:osd0=720x576x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=$(videostd) Also note that you need to have root=/dev/nfs in bootargs. Hope this helps.
