Diagnosis begins with a systematic approach. 1) Visually inspect the SPI wiring for any damage or looseness. 2) Check the SPI clock signal using an oscilloscope or logic analyzer. 3) Verify the power supply voltage is within the specified range for both the SPI controller and the SPI device. 4) Consult the datasheets of the SPI controller and SPI device for specific error code interpretations and troubleshooting steps. 5) Test the SPI communication with a known good SPI device.
