Hi Dave,

The problem is solved.
But i have one doubt.

So the PC is 0, and the LR is C92F. That tells me that the code at
C92F in your init process is trying to call a function through a NULL
pointer. You can try disassembling your init process. Something like
quoted
arm-eabi-objdump --disassemble init
In this case we came to know the process name 'init'. But in some
cases we might just have the link register address, and no process name.
say some user-space process has caused the panic.

Can u tell me ..how to debug in that case?
You should always have a pid & process name if its a user-space app
which dies (at least if you enable CONFIG_DEBUG_USER and enabling
user_debug)
