    Hi Pavel,

    I find the reason.After removing the ip=dhcp from the bootargs ,it is ok.

    But I don't know why .Is it related  to the file system mounting ?

    Bob,

    I also tried with the below bootargs (also with ip=dhcp) and it works fine on my side:

    TI8148_EVM#setenv bootargs 'mem=200M console=ttyO0,115200n8 root=/dev/ram0 initrd=0x82000000,40M ramdisk_size=32768 ip=dhcp'

    Kernel command line: mem=200M console=ttyO0,115200n8 root=/dev/ram0 initrd=0x82000000,40M ramdisk_size=32768 ip=dhcp
