roberto from spain has made a modified Qi bootloader for the SmartQ 5 MID that can boot from the external SD card, as a convenient way of developping or testing OS, or for system rescue purposes in case of internal flash corruption. This is the bootloader operation:

  • Search for a valid ext2/ext3 partition in the SD card (4 primary partitions).
  • If the file /boot/noboot-SDMK6410 exists, it will skip that partition and try the next one. Useful for disabling partitions temporary.
  • Load and run the kernel image from file /boot/linux-SMDK6410.bin (if it exists). It should be on uImage or zImage formats.
  • The optional file /boot/append-SMDK6410 can be used to specify additional kernel arguments.
