AM5716: Errata i862: Method for identifying WDT_RST occurrence

$

Part Number:AM5716

Hi Experts,

I'd like to identify that WDT_RST is occurred when AM571x is reset. However, due to the circuit that avoids Errata i862, it seems that PRM_RSTST is always '1' (GLOBAL_COLD_RST) after any resets.

Do you have a good way to identify WDT_RST? Also, what does the following method described in Errata specifically mean? What should I do?

"To maintain some visibility software may be able to store information in PMIC BACKUP or other PMIC registers."

Regards,
Kzk
