Important

If you are looking for BlueSCSI v2 documentation please go here: https://github.com/BlueSCSI/BlueSCSI-v2/wiki

BlueSCSI will try to communicate with your SD card at full and half speed SPI before giving up.

If your card is communicating at 25MHz it has about a 5% performance hit (not much, but worth investigating!)

Try the following to resolve:

  • Check for bridges on your SD card holder
  • Update to the latest firmware
  • Do a full overwrite format with SD Formatter
  • Clean the SD Card contacts with IPA and let fully dry, a bad connection can sometimes cause this.
  • Try a different SD card, some SD cards may not be able to communicate at full SPI.
