I put the u-boot at 4x64kiB (sector 0x200) offset on the sdcard. With CONFIG_SPL_ABORT_ON_RAW_IMAGE config enabled the spl scans first for the configured partition in the partition table as implemented by Dalon, if that fails it tries to find the u-boot at sector 0x200 (as configured by CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR). Without that config the spl endless retries to find u-boot in the configured partition, which is not there when using GPT. > > Also, i mentioned before that i would like to hold off on this patch set and > let Ley Foon et al finish the A10 stuff. > > --dalon > >> _______________________________________________ >> U-Boot mailing list >> U-Boot@lists.denx.de >> http://lists.denx.de/listinfo/u-boot > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/listinfo/u-boot
