https://community.nxp.com/t5/S32K/Adapting-MCSPTR2AK396-reference-firmware-AMMCLIB-FreeMASTER-for/m-p/2415349#M61152 <P>Hi,</P> <P>The changes you described (high-side current sensing, different gate driver architecture, PWM polarity changes, and the associated motor-control software adaptations) represent a significant shift from the MCSPTR2AK396 reference design and require substantial modifications to the reference solution.</P> <P>Due to the project-specific nature and complexity of this work, we are unable to provide a complete migration guide through the standard support channel.</P> <P>For dedicated assistance with adapting the reference software to your custom hardware, please consider engaging NXP Professional Engineering Services:</P> <P><A
