[U-Boot-Users] PPC405GP - uboot - can't get past stackloop

[Jerry Walden]

Greetings:

	I have managed to learn how to use GDB, and DDD with the BDI-2000 to start
to debug
      my bootrom.  I can load source, and symbols etc...

	So - here is where I am stuck.  First, I am using u-boot with the
WALNUT405GP config.
	My board is a custom board with a 405GPr on it.  The memory map looks the
same as
	the development kit (or at least we tried our best).

	Now - I start tracing from the _start, and I get to:

	..stackloop
		stwu	r4, -4(r2)
		bdnz	..stackloop



	If I set a breakpoint after the bdnz, the debugger never breaks - it is
though it is in
	an infinite loop.

	If I "interrupt" in DDD, the following message is displayed:

	Program received signal SIGSTOP, Stopped(Signal)
		0x00000700 in ??()

	Any hint as to what might be going wrong?

	Thanks

	Jerry
