I have verified myself and ask one of my colleague to double check it, but the Kernel Hacking is already disabled. However it seems there's some thing relate to your supposition, I can run the kernel without stopping BDM by command: g 100000 (or any random number). That's fine for me at this time, but it's still a question : BDM problem or kernel problem????? Another problem I have is: - After the kernel initializing and running, if I stop the BDM to view some registers and start again. The BDM will stop and report an breakpoint happen if I try to press any key on terminal. Any advices ???
