How to fix "Failed to initialize SD card -ENODEV" error on AVR128DA48 using SPI?
Hey @Dtynin It sounds like you've covered most of the basics, but the
-ENODEV error suggests that the SPI device may not be recognized correctly. re-check that the SD card module is powered properly and that the chip select line is correctly configured. It might also help to slow down the SPI clock speed to ensure reliable communication. Also, confirm that the SD card is compatible with the SPI mode and consider using a different SD card if possible to ensure proper initialization sequences in your code or using an SD card library optimized for the AVR128DA48 might also resolve the issue.2 replies
