Hi Board designers,
Refer below recommendations for AM62A SK hardware changes to testing Partial IO LPM
USB
The USBx_DRVVBUS used to enable the USB power switch has an internal pulldown enabled during reset and after reset.
In the SK, an external pullup is provided. This needs to be enabled.
In any of the SK if a external pullup or pulldown is provided, both of these pulls should be made DNI.
UART
The below document describes the changes to be made
Pad Configuration
Refer Bit-29
