[U-Boot-Users] Uboot mpc8xx porting

[Vishwanath Patil]

As is understand by seeing the code, there is a bd_info structure that
the U-boot sends to the kernel through registers. Now one of the main
information that is passed on is the address of the start of the
bd_info structure in the memory. At the end of the structure the last
member is again a structure pointer that points to monitor routines.

I have a U-boot working fine, i have tested example applications on
our target board and found everything is fine. Does this mean that the
monitor routines are fine. When i try to load kernel, the kernel
executes some code in head_8xx.S and hangs. As told in the Readme file
i have checked with the IMMR start to be matching with ppcboot.h.

Why is the Kernel hanging? Will the Kernel use the getc,puts and other
monitor functions of the U-boot for messages? How do i proceed? I have
tried with both uclinux and linux kernels on the board.

Any information will be of great help

thanks
