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?
