 | Hi,
I'm encountering a strange problem with some code on a Motorola 56858
EVB. I'm using CW for 56800/E v6.01 and the parallel port BDM
connection, and I have evidently done something... unusual... at a
particular point in my software, because the debugger actually loses the
connection to the target. This makes it a bit difficult to debug. I
didn't think this was possible, but I can tell from LEDs and serial port
activity that my code continues to run. The code must be the cause of
the disconnection because the BDM has been perfectly reliable otherwise
and quite repeatably goes wrong when I enter this particular section of
it - which does involves processing a lot of interrupts.
Does anyone have any idea what sort of sin my code has to commit to
disable the JTAG/EOnce BDM?
TIA
Nigel
