Most boards are +shipped with the redboot bootloader, newer boards are shipped with a combination +of a shim (U-Boot based) non interactive loader and a Linux based rescue system +called 'Flash-N-Go'. + +Santaro (i.MX6) +--------------- + +This board comes with Flash-N-Go. It boots from the internal eMMC boot0 partition. +To put barebox on this board boot the system up in the Flash-N-Go system by holding +the user button pressed during startup. The barebox image can be transferred via +network or any other medium the Santaro supports. You can backup the original bootloader +with: + +.. code-block:: sh + cat /dev/mmcblk0boot0 > /mnt/mmcblk0boot0.backup + cat /dev/mmcblk0boot1 > /mnt/mmcblk0boot1.backup + +The original bootloader can be restored by copying the backup files back to the +device. + +To install barebox on the board do: + +.. code-block:: sh + echo 0 > /sys/block/mmcblk0boot0/force_ro + cat barebox-guf-santaro.img > /dev/mmcblk0boot0 + +The board will come up with barebox after restart. Should you end up with a nonworking +barebox or otherwise brick your board this way write a mail to s.hauer@pengutronix.de. +There's a way to put the board into SD/USB boot mode, but this requires opening the case. -- 2.1.1 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
