It might not be the right place to ask, but is there a way to identify
if a JTAG adapter (ex: IAR JLink) is connected or not.

I work on a multi processor environment, and software workflow is 
affected by the fact that debugging might be in progress" on another 
controller.


Thanks

Already answered in the archives here.

The TRSTn line is driven active high by a good JTAG, use a pulldown resistor
on your board to be sure it's low when the JTAG is not connected. Sense the
line level with a spare GPIO pin (a spare pin is the hardest part...).
