MCU-PLUS-SDK-AM263PX: Control Card SDK examples PMIC Inclusion

Part Number: MCU-PLUS-SDK-AM263PX

While testing SDK examples on the AM263Px Control Card, I noticed that some, but not all of the examples include the PMIC TI Board Driver.

The EVM User's Guide (SPRUJ86A) makes it seem like the PMIC is important to the correct functionality of the Control Card.

What criteria determines if the PMIC was included in the SDK examples?

If I am testing using projects based on these SDK examples, how important is it that I include the PMIC TI Board Driver?

    Through some investigation I think I can answer my own question.

    I believe the inclusion of the PMIC TI Board Driver depends on whether certain peripherals are used. For instance, SDK examples that use LIN need to enable LDOs managed by the PMIC. These LDOs power MUXs, and other components that the peripheral depends on.

    Hello TollMan,

    Sorry I wasn't able to get back to you sooner, but you have the exact answer figured out. The PMIC doesn't have all rails turned on by default, so for specific examples like LIN which requires additional rails, the PMIC driver is required.
