The code running on my MSP430F5524 isn't responding to external inputs(such as a keypad) atter running for a short while. On certain occasions the code is able to enter the ISR(Timer, UART).
On putting the programmer, I am unable to pause the code. I am getting the message "Break at address "0xd00c4" with no debug information available, or outside of program code".
Any idea why this is happening and how can I resolve this? Could the code be getting into a "bad state" because of not handling an interrupt/doing an illegal operation like dividing by 0? However, in case of not handling an interrupt the code should enter the "default" ISR provided by TI and enter into a LPM Mode( I have forgotten the exact name of this).
The same code is working fine on other PCBs with the same schematic. Could this be a hardware issue in terms of design/layout?
We are in a critical stage of our project. Any help would be appreciated.
Thanks and Regards
