Hello, all.
A program, before it can run at it's runtime address, it has to configure the
memory, copy itself to the memory,
or enable the MMU; after these, it can run at it's runtime address.
My question is, how can I debug it with OpenOCD and gdb, when it does not
run at it's runtime address?
This is a example, when I debug the linux kernel, the gdb command 'break'
can't work before the MMU
is enabled , the address of the break point does not exist yet. My method is:
telnet the OpenOCD, 'step' to
the instuction 'turn_on_mmu. Just after the MMU is enable, I can set the break
point use GDB.
But this method is difficult for newbie.
Do somebody have a easy way?
