Using the latest git clone I've tried this for configs/omap3_beagle_defconfig: CONFIG_SPL=y CONFIG_SYS_EXTRA_OPTIONS="NAND" CONFIG_SPL_EXT_SUPPORT=y CONFIG_SPL_FAT_SUPPORT=n +S:CONFIG_ARM=y +S:CONFIG_OMAP34XX=y +S:CONFIG_TARGET_OMAP3_BEAGLE=y and also this: CONFIG_SPL=y CONFIG_SYS_EXTRA_OPTIONS="NAND" +S:CONFIG_ARM=y +S:CONFIG_OMAP34XX=y +S:CONFIG_TARGET_OMAP3_BEAGLE=y +S:CONFIG_SPL_EXT_SUPPORT=y +S:CONFIG_SPL_FAT_SUPPORT=n Is this the right way to turn off FAT support? Neither way boots to a u-boot prompt. Also, the working F20 image starts partition 1 on cylinder 1953: Device Boot Start End Sectors Size Id Type /dev/sdb1 * 1953 41015 39063 19.1M c W95 FAT32 (LBA) /dev/sdb2 41016 1041015 1000000 488.3M c W95 FAT32 (LBA) /dev/sdb3 1041016 61497343 60456328 28.8G 83 Linux whereas for F21 it starts on 2048. Device Boot Start End Sectors Size Id Type /dev/sdc1 * 2048 1001471 999424 488M 83 Linux /dev/sdc2 1001472 2001953 1000482 488.5M 83 Linux /dev/sdc3 2001954 9814453 7812500 3.7G 83 Linux Fdisk doesn't let me change it to before 2048. Does MLO need to be on the disk before sector 2048?
