    I’ve built an image and put it on my SD card, but the Minimorph won’t boot.

    Check these things:

    • You have converted your image to U-Boot format and named it ‘vmlinux.ub’.
    • Your SD card is formatted as FAT32.
    • The vmlinux.ub file is at the root of the SD card.

      Also, make sure that there is no file named ‘u-boot.scr’ in the root of the SD card.

      Edit:
      I should clarify this a little better: make sure that there is not a spurious ‘u-boot.scr’ file on the SD card. U-boot attempts to read and execute this file on startup, and if it is malformed or points to an incorrect image then boot issues are likely to arise.
