    • [SOLVED] SPI noise


      I am a beginner of emFile. Now I can build and write file to my SD card (SPI interface). Now I am testing continuous file write in noisy environments. And I find the FS is corrupted occasionally. I think this is due to the noise on SPI bus. Any suggestions to improve this?

    • Hello Caster,

      You can try to enable the CRC verification of the data via the FS_MMC_ActivateCRC() API function to check

      if it helps preventing file system corruptions.

      The emFile SPI MMC/SD driver retries a data read operation (up to 10 times by default) if it detects a CRC error
      in the data received from SD card.

      Best regards,
