Hi Jason,
Some good news. I switch the GDB command set from mi to
mi1, and it seems to be working now.
What I did is added the kgdbwait command to the bootargs as follows (not sure
if it was necessary, but will try once again without it)
setenv mmcargs 'setenv bootargs console=${console} vram=12M omapfb.vram=0:4M
omapfb.mode=dvi:${dvimode} omapdss.def_disp=${defaultdisplay}
root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait kgdb=${console}
kgdboc=${console} kgdbwait'
Then I launched the debugger, and it did something, and resumed normally.
Then I manually went to the console and activated kgdb by typing
echo g > /proc/sysrq-trigger
This caused the debugger on the Eclipse side to process something, and then it
stopped in file kgdb.c at the call to arch_kgdb_breakpoint(), in the following
method:
void kgdb_breakpoint(void)
{
atomic_set(&kgdb_setting_breakpoint, 1);
wmb(); /* Sync point before breakpoint */
arch_kgdb_breakpoint();
wmb(); /* Sync point after breakpoint */
atomic_set(&kgdb_setting_breakpoint, 0);
}
I can now clearly see all the registers and variables in Eclipse.
Question 02: sys_sync doesn't seem to be called in the ARM arch files, it only
exists for x86 and sparc architectures.
Is there any other kernel file I can set a break-point into, to be able to
check if everything is working ok?
For example, if I type a normal cd or ls command?
Best regards,
Elvis
