Hi Vivek, I found this link https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/501981?Watchdog-timer-for-Concerto-C28x in which you mentioned how to set up NMI C28x. Force NMI on C28x by setting a flag in CNMIFLGFRC register. This will generate NMI on C28x. Inside NMI handler wait for CNMIWDCNT to timeout (you could modify the CNMIWDPRD to minimize the wait) so that it resets the C28x. Reset on C28x will generate NMI on M3 In M3 NMI handler again wait so that MNMIWDCNT times out and issue a reset. This will reset full device/system. I am unclear about the first step. Can you explain where this step has to be done? Is it on the main loop?
