Welcome to the wonderful world of BDM. The bottom line is the BDM
software is likely initializing something in the processor that you are
not doing in your code. This is an all too typical problem I have
seen in many organizations, and is the reason the first thing I do
is write processor boot roms and initialization, then throw the BDM
away before even starting on the kernel.

Yes, indeed, you are missing something in your code.
