→MMC Recovery
=== MMC Recovery ===
Due the fact that MMC is both removable and accessible on a system that support this device, MMC recovery is a valuable options that requires no special hardware at all, apart a properly formatted MMC.
For more information about MMC booting see its dedicated section inside [[Boot sequence (Naon)|Naon boot sequence]].
After the board is booted via MMC, if you have U-Boot console access and a serial terminal emulator (and, of course, a PC), you can follow the standard [[Flashing Images (Naon)|Naon Flashing Images instructions]] to restore the broken bootloader (it's useful to have this binary image on MMC too)
If you are on-site without even a console access (or a skilled user that can send commands via serial console), a better way to recover the board is to prepare a custom U-Boot image as boot binary into the MMC with runs the update (and verify!) commands as soon as it's booted. However this is an advanced topic and requires a customization that is heavily system dependent. Feel free to [[HowTo Contact Technical Support|contact us]] for more information and help.
