Hi all,
I am using uboot and montavista kernel for our custom MPC8555CDS board.
I enabled the following options in Kernel for kernel Debugging,
CONFIG_BDI_SWITCH=y CONFIG_DEBUG_INFO=y under kernel hacking and MMU XALT in
BDI config file. After uboot initialization I fixed break point at
start_kernel(0xc02784bc), and then I booted the kernel. Without breaking at
start_kernel, it came to login prompt. Please find attached config file with
this mail. Could anybody help me to solve this problem?
Thanks in advance,
Saravanan.S
Bangalore.
