Re: BDI kernel debug

Hello,

quoted

Are there some options in the kernel or in the gdb to set ?

Did you enable CONFIG_DEBUG_KERNEL in your kernel configuration?

Yes it is enabled, furthermore the "Include BDI-2000 user context switcher" is set and compiler options "Additional compile arguments: "-g -ggdb -fno-schedule-insns -fno-schedule-insns2" are set

Did you read the FAQ section of the DULG, especially
http://www.denx.de/twiki/bin/view/DULG/HowToDebugLinuxExceptions
and
http://www.denx.de/twiki/bin/view/DULG/HowToSingleStepThroughRFIInstruction

In my case i try to step through m8260_setup_arch() function to debug m8260_find_bridges() for pci support. Is there the MMU already on ?
I think it is.

When the bdi runs through the code the most time it comes to the __delay() function. Then i try  "step" or "next" and it often hangs forever.

Wolfgang Denk
