Hi All,
Any one tried to debug the taget(ARCH=powerpc) using kgdboc.
I tried following steps:
1. Configure and compile the kernel for target machine.
> make menuconfig
*Under kernel Hacking:
- enable KGDB and KGDB over serial console
CONFIG_KGDB=y
CONFIG_KGDB_SERIAL_CONSOLE=y
- enable the magic SysRq key
- enable "Compile the kernel with debug info"
2. Configure target
* Enable Magic SysRq key on target
- Edit /etc/sysctl.conf and set kernel.sysrql =1
3. Start debugging
a) On Taget
- Set the bootloader parameter as *kgdboc*=ttyS0,9600
- Boot the Image
b) On Host side
(gdb) <arch>-gdb ./vmlinux
(gdb) set remotebaud 9600
c) After Booting on Target
- echo "g" > /proc/sysrq-trigger
-
An attempt to run "target remote /dev/ttyS0" on my
host and getting: Ignoring packet error, continuing...
Malformed response to offset query, timeout.
Please help me out with your suggestions.
Thanks and Regards
