Hello all,

recently I encountered a very strange behaviour of a MSP430F149 during JTAG
use:
When I program the controller via JTAG (and jtag.py), due to some reason,
the controller sticks in a mode which can not be left, not even with a
manual reset (pulling reset pin low). The only way to recover is
interrupting the power supply. This happens in one out of 5-10 cases. My
problem is: the device is driven by a rechargeable battery mounted on the
board, and the board is fixed upside down in a can-shaped housing. This
means I have to unscrew the board, unplug the battery, shorten the supply
pins to discharge capacitors, press the reset button (just in case), connect
the battery again, mount the pcb and wait for the next time it happens. Very
uncomfortable...

Has anyone else seen this problem?

Regards,
Ralf
