DRV2625: calibration routine returns error

Part Number: DRV2625

Parameters being set are listed below (anything not listed is using the register default value):

  • 0x07 – 0x43
  • 0x1F – 0x51
  • 0x20 – 0x5A
  • 0x27 – 0x1F
  • 0x2E – 0x01
  • 0x2F – 0x22

Register 0x01 invariably returns 0x88. This is the datasheet for the LRA

Can you please suggest strategies for debugging the problem?

Thank you!
