mpc85xx with sata harddisk,which has a rootfs on sda3.
I ' ve tried to use freescale's kernel image , which is togehther
with the mpc85xx board, to successfully mount the sda3 filesystem when
But when I used my own kernle, it failed:
I am using kernel 18.104.22.168 to mount the harddisk as the rootfs.
However, it failed in booting and print:
VFS: Cannot open root device "sda3" or unknown-block(0,0)
My kernel's bootargs are as followed:
root=/dev/sda3 rw console=ttyS0,115200 console=tty0
I guess there were some incorrect configs when doing kernel
menuconfig, I' ve set "ext2,ext3", and some "sata" ,"scsi" configs,
but that might be not enough.
May anyone please give me some suggestions?
THX in advance.
