Workarounds

  1. 90% success Verify CPOL/CPHA settings match slave device requirements
  2. 88% success Check CS pin timing and SPI clock speed vs slave maximum

Dead Ends

Common approaches that don't work:

  1. Increase SPI clock to maximum 82% fail

    Signal integrity issues

  2. Ignore SPI errors and retry 78% fail
