Platform: i.MX6 (booting from NAND) I would like to be able to update Barebox from Linux using a framework like RAUC or swupdate. The RAUC documentation states: https://rauc.readthedocs.io/en/latest/advanced.html#bootloader-update-ideas > 7.6.3. Bootloader Update Ideas > > The NXP i.MX6 supports up to four bootloader copies when booting from NAND > flash. The ROM code will try each copy in turn until it finds one which is > readable without uncorrectable ECC errors and has a correct header. By > using the trait of NAND flash that interrupted writes cause ECC errors and > writing the first page (containing the header) last, the bootloader images > can be replaced one after the other, while ensuring that the system will > boot even in case of a crash or power failure. > > The slot type could be called “boot-imx6-nand” analogous to eMMC. In the barebox documentation I only found how to update barebox via the barebox_update command within barebox itself. Updating barebox seems to be SoC specific. Is there already any existing code to do this from Linux? Or would it be more wise to write the new barebox image to a temporary UBI partition and let barebox do the update itself on next reboot? regards Christian _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
