Hello,

What's the failure rate you have? Can you please provide searchable PDF schematics for this kind of debug?

Thanks!

Phil

MPU_AM572.pdfWe have referred AM572 EVM schematics. We are unable to power ON the PMIC. Pls let us know whether any hardware/firmware settings has to be carried on in order to power ON the PMIC.

Since the PMIC is OFF, MPU interfaces that require supply from PMIC are OFF. So help us to make them work.
