[Openocd-development] How to debug a program not run at it's runtime address

[dswei <ds...@si...>]

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?
