Re: remote debugging and source files

Hmm...according to your info shared, you have the loader here:

0x40001460  0x40011914  No 
/opt/arm-linux/gcc-3.3.3-glibc-2.3.2/arm-softfloat-linux-gnu/lib/ld-linux.so.2 


so the breakpoint doesn't seem entirely unreasonable.  Is there any 
possibility that you have a different ld-linux.so.2 on the host and 
target?  Then gdb would be calculating the breakpoint incorrectly based 
on the host loader.  If you take a look at /usr/include/link.h, you'll 
find the r_debug structure.  The comments in there will help you 
calculate the breakpoint by hand (look at the r_brk element) and then 
you can compare it to what gdb is coming up with.

cheers,

Kris
