I want to boot the camera using nfs server.
It's the boot command and argument :
setenv bootcmd 'tftpboot 0x80700000 uImage_ipnc_DM368_IMX036_NFS;bootm 0x80700000'
setenv bootargs 'console=ttyS1,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=166.104.231.74:/home/kim/ipnc/target/rdmnt2,nolock mem=46M'
And, Here is my log :
