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. > Best regards, > > Wolfgang Denk Thank you for your reply.
