medium📝 Debug Q6 of 15
Step-by-Step Solution
Solution:
Step 1: Check SPI device file absence reasons
If SPI device files are missing, the SPI kernel module might not be loaded.Step 2: Understand unrelated causes
SD card corruption or power issues cause broader failures; Wi-Fi status does not affect SPI.Final Answer:
The SPI kernel module is not loaded -> Option BQuick Check:
Missing SPI files = kernel module not loaded [OK]
Quick Trick: Load SPI kernel module if device files missing [OK]
Common Mistakes:
MISTAKES- Blaming unrelated hardware issues
- Ignoring kernel module loading
- Assuming Wi-Fi affects SPI
