HI, Expert,
Our customer will use the AM62P PMIC watchdog function. After enabling the function, when timer out, it will raise Soc Power down, but the system can't bring up.
1. Have we tested it on AM62P EVM ? pls help to test on your side.
2. If it works well, pls share the steps to run on EVM, We will try to reproduce on EVM .
Regards,
Fredy Zhang

If the query is on watchdog in the PMIC, I am reassigning this to PMIC team first.
Sorry for the delay - looks like this was mis-assigned. Looks like this is being escalated, but please note the thread was opened on Friday and Monday was a TI US holiday. Responses may take a couple of days.
Hi Fredy,
Could you confirm what PMIC you're using on the AM62P EVM: TPS6594 or TPS65224? The original developers wrote and tested the functionality, but I will do my best to look into the solution. If there is any other information that you think would be helpful for me, please send that my way.
Thank you!
