You should never store raw zImage/dtb in a flash on a production system. This is real bad and can result in a corruption in the future when the system is in the field for a long time. I'd suggest to just use two UBI volumes, one for fitImage and the other for rootfs. > But the rootfs partition still can be presented to Linux as ubifs. That's for sure :) Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
