TPS65381 reset cause

Other Parts Discussed in Thread: TMS570LC4357

Hello,

We are using the TPS65381 with a TMS570LC4357. I am implementing the watchdog and DSP error (ERROR/WDI) management. Everything is working ok, my only problem is determining the reset cause when a reset occurs.

After a reset, is it possible to know if it was a watchdog reset or a DSP error reset?

After a reset, I would expect to find the cause in SAFETY_ERR_STAT in bit WD_FAIL and  ERROR_PIN_FAIL but they are 0.

Thanks,

Martin
