Hi all,
I am using freescale mpc5200B on the board. I have a
tftp-server on my machine and connect to the board
through this server.
the Kernel and the root file system are ion my
desktop PC in the directory /tftpboot/
kernel ---> /tftpboot/pImage
root fs ---> /tftpboot/rootfs/
We have U_Boot for booting system and it fetches the
kernel from the server (that is my esktop PC) through
the ETHERNET connection. rootfile systems stays here
in the server ,
ls command shows like this in /tftpboot/rootfs/
[root at localhost rootfs]# ls
bin build_dir deep_sleep dev etc lib mnt opt
proc sbin tmp usr var
console interface is console=ttyS0 on to the board
now the problem is that if i use MPC5200 Rev A then
the kernel boots without any problem and gets into the
command
but when i am using MPC5200 Rev B it shows like this
