    Hi,

    The waveforms you provided are captured when programming the flash? It shows substantial noise.

    The difference is having the 3-phase compressor motor connected to your board vs not connected and motor is not running? There's no other differences? Are PWMs to the IPM held LOW / OFF during programming?

    Best,

    Kevin
