several sources on the net suggested that interactive debuggers on the kernel are a bad thing so I pushed it down on the todo kernel-skill stack so I dont yet know how to use qemu's gdb with the kernel
it is described in qemu wiki website actually. I found it here: http://www.elinux.org/Virtual_Development_Board jump into 'Debug U-Boot" section. Of course, adjust the parameters so that it boots your kernel name and you invoke the qemu arch of your choice. The rest is the same. Other thing that I recall is sometimes Qemu had trouble when debugging interrupts....or in general things that works periodically.
Good news is I found the error (not me the folks at batman's irc channel did) the
memcpy(tvlv+sizeof(struct shortTvlv),value,length*sizeof(uint8_t)); needs to be memcpy((char *)tvlv+sizeof(struct shortTvlv),value,length*sizeof(uint8_t));
great!! :) casting mistakes, right?
thanks for the assist everyone and if you have any good tutorials on qemu + kernel +gdb i'll be thankfull
See above :) google might reveal more IMHO -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
