TMS320F28379D: The interrupt start time of two CPU timers is different

Part Number: TMS320F28379D


Dear team:

Both CPUs use timer interrupt. The timing time is the same. The offline mode is used to run. Timer 0 is configured in CPU 1 and timer 1 is configured in CPU 2.

CPU 1 uses timer 0 to trigger interrupt, CPU 2 uses timer 1 to trigger interrupt. However, it is found that the start time of two timers is different, and CPU2 is later than CPU1. And even if I change the timer interrupt of CPU 1 to timer 2, the interrupt start time of CPU 2 is always later than that of CPU 1.

What should I do if I want the timer interrupt of two CPUs to start at the same time?

Best Regards
