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.

Ok, I've found the reset pin on PXA255 and wired it to correct pin on BDI2000, but still the same error appears :(. Should there be any other pullup/pulldown resistors on other JTAG lines besides reset or does BDI hava them 'built in'?
