Hi,

Sorry for the delay, will respond by next work day or two.

Hi,

AM62ax has  A53 cores, not a72 cores.

Please look at the  Data sheet: https://www.ti.com/lit/ds/symlink/am62a7.pdf?ts=1693525559151&ref_url=https%253A%252F%252Fwww.ti.com%252Fmicrocontrollers-mcus-processors%252Farm-based-processors%252Fproducts.html
and device TRM:https://www.ti.com/lit/ug/spruj16b/spruj16b.pdf?ts=1693525585611&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FAM62A7

for more information.

I will link a nice wiki showing the differences between arm cores: https://en.wikipedia.org/wiki/Comparison_of_ARM_processors

Here is an app note for AM62ax that can help understanding A53 core performance: https://www.ti.com/lit/an/sprad90/sprad90.pdf?ts=1693525372100&ref_url=https%253A%252F%252Fwww.google.com%252F

Here is a user guide for PMIC on AM62ax: https://www.ti.com/lit/ug/slvucm3/slvucm3.pdf?ts=1693525638692&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FAM62A7

Will forward this thread to PMIC expert.

Arvind,

The u-boot PMIC driver is not required for device functionality, but it was proposed at one point. Those patches are not present in the 09.00.00.08 SDK. Was there something in particular you were trying to achieve with the PMIC that required the u-boot driver?

Regards,
