Hi
> Can somebody point me to the possible causes for this behaviour?
Reset line.
> PS. Is it mandatory to supply ~RESET pin to BDI?
Yes.
BDI2000 uses ~RESET to upload the debug handler into the mini IC.
See figure 10-11 in the Intel Xscale Microarchitecture User's Manual.
> Can I just keep it in reset with a jumper closed?
Well, if you can match the timing and probably you should have a
pull-up on the ~RESET line of the JTAG connector to the BDI2000,
but I doubt it.
