TMS320F28035: Can I connect a C2000 chip that is running offline through emulator + CCS

Part Number: TMS320F28035

Dear team:

My client's chip often crashes during offline operation. He hopes to connect JTAG to observe the operation of internal programs when the chip crashes. Can C2000 chip do this? How to realize it?

Best Regards

    Green,

    I think the issue if the customer tried to connect through the JTAG after the program crashes is that either the device may not connect or the state of the chip may be changed.  I think there are some settings in the connection properties(or the GEL file) that customer would need to either change or just remove the GEL file.

    The other option is to have the JTAG/CCS connected and run the program manually and when they observe a system issue just halt the CPU and observe the state of the program counter(where the code is at) and back trace from there.  I would also make sure any kind of WD or TRAP ISR instructions have some code that will just loop if those are triggered so they can observe the state of the device.

    Does customer have idea what happens when the device/system crashes?  For instance are all the PWMs "dead" or is just the duty cycle bad, etc?  That would give us a clue where to look.

    Best,
