"Load" problem

"Load" problem

[Mitchell Fang]

Has anybody run into this "load" problem before?  Looking at the error
message it says it's due to it failing at the function
target_write_memory_partial in symfile.c.  The thing I don't get is
whether this error is due to error in transferring the program to the
target or is this something wrong with gdb running on the host
machine?  When I look at the remote log file I'm pretty sure that I
wrote the program to memory and returned OK.

A little background on what I'm doing.  I'm implementing a GDB stub
thats connect GDB running on a linux machine to a PowerPC4xx eval
board (target) via a JTAG controller.

My testprog program is extremely simple.
#include <stdio.h>
#include <stdlib.h>
int main ()
{
	int i;

	i = 51;
	printf("i = %d", i);
	return 0;
}

gcc -c -g testprog.c
gcc -o testprog testprog.o


Thanks,
Mitchell

Use GDB 6.4 instead, which contains a fix.

Might have better luck down the line if you use a PPC cross-compiler
:-)
