Hi All, I am porting Linux on MPC8266 custom board, after getting in to Linux the system seems to be struck at a point. Saved Environment variable:- bootargs console=ttyS0,11520 root=1f00 and downloaded the Kernel image at address 0x02000000 in the RAM.
From the u-boot prompt the bootm command is invoked as:-
bootm 0x02000000
After that what I get on the terminal is pasted below for your reference. I couldn't make out any thing from the output, can any body tell me where I am doing wrong, and also I don't have any idea about the bootargs argument "root". Can any body give the precise description of this argument?
