Re: BDM problem

Hoang,
When you are trying to use the Avocet Systems HMI BMD device
have you built a kernel with Kernel Hacking disabled? It appears
from your description the it is still enabled. When kgdb is enabled
through kernel hacking, it starts and immediately hits a breakpoint.
If you at this time set a breakpoint further on then you should be
able to proceed. If you want to use the HMI BMD then you need
to un-select kernel hacking and rebuild your kernel.
