Problem in Debugging prx with psplink + psp-gdb

poison · Post by **poison** » Sat Aug 18, 2007 4:20 pm

I got static elf worked well in the usbhostfs + psplink + psp-gdb debug environment, I could add breakpoint/memory monitor or change variable etc. but on luck in prx module debugging..
here is my step:
launch psplink 3.0 OE in PSP
start usbhostfs_pc and use pspsh to get the shell
type debug ./XXX.prx
then gdb ./XXX.elf and target to 127.0.0.1:10001(actually I got Eclipse to do this for me)
if I define the stop point in startup at "module_start"(_start), I got

Code: Select all

Previous frame identical to this frame &#40;corrupt stack?&#41;

and no any other signal
if I define it "main_thread"(I know it's wrong), I got

Code: Select all

Previous frame identical to this frame &#40;corrupt stack?&#41;
&#91;Switching to thread 60432969&#93;
warning&#58; GDB can't find the start of the function at 0x88267d28.
Previous frame identical to this frame &#40;corrupt stack?&#41;
warning&#58; GDB can't find the start of the function at 0x88267d28.
Previous frame identical to this frame &#40;corrupt stack?&#41;

It said "Suspended: Signal 'SIGTRAP' received."

could somebody figure out what's the wrong? thx
