The target indeed stops in boot waits for the gdb to set up breakpoints, .... So I used set solib-path-search command in gdb to set up my driver location and set a breakpoint within my driver. Gdb warned me that currently this symbol is not visible and will become visible on library load. Ok , I entered gdb> cont command, the target computer succesfully booted. Then I load my module on target hoping that gdb will hit a breakpoint because the functions I asked to stop in are inside module initialization code - but nothing happened. What do I miss here ? There's a chance that the breakpoint address you have set is no longer correct since symbol relocation happens during module insertion. For example: # cat /sys/module/ip_tables/sections/.init.text 0xe00fe000 # nm ip_tables.ko | grep init 0000000f T init_module What do you think? regards, Mulyadi. Since I use function name, the gdb will resolve it ti address on module load event gdb >b MRouterBindAdapter gdb>_   Function "MRouterBindAdapter" not defined. gdb > Make breakpoint pending on future shared library load? (y or [n]) y I have set 2 pparamers for shared lib set solib-prefix /dev/null set solib-search-path  /home/2.6.26/ I think I miss somthing on how to setup solib-search-path, or some connected to shared library load parameters Regards, Lev PS BTW, I do not see my post in web archive at  -http://mail.nl.linux.org/kernelnewbies/2009-02  ??? -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
