Hi all,
I'm new to uClinux and i'm working on a custom board with mcf5235. Running the
kernel was quite simple but i'm having problems to debug applications. I'm using
gdbserver with an ethernet connection. My dist is 20070130 and I tried to
use
gdb in m68k-elf-tools-20030314 and a recompiled version of gdb 6.6 for
m68k-elf targets.
The first give me these errors:
(gdb) target remote 192.168.0.23:3000
Remote debugging using 192.168.0.23:3000
0x00e00048 in ?? ()
(gdb) x main
0x676 <main>: Cannot access memory at address 0x676
(gdb) b main
Cannot access memory at address 0x676
(gdb)
the second seems to work a little better:
(gdb) target remote 192.168.0.23:3000
Remote debugging using 192.168.0.23:3000
0x00e00048 in ?? ()
(gdb) x main
0x676 <main>: 0x4e56fef4
(gdb) b main
Breakpoint 1 at 0x690: file test.c, line 227.
(gdb) c
Continuing.
Warning:
Cannot insert breakpoint 1.
Error accessing memory address 0x690: Input/output error.
I patch the file entry.S as said in
http://mailman.uclinux.org/pipermail/uclinux-dev/2007-June/043181.html
Any ideas on what can be wrong? I have to use a particular version of gdb?
I hope this qustion is not too obvius but I don't know how to face this problem.
I'm a newbie so I'm probably doing some stupid error!.
Thanks!
