I forgot to mention that I additionally enabled option CONFIG_EFI_PARTITION to get GPT partition support. @Fabio, can we add this option as well? > Can you just update the commit message in how you perform the update? I booted the board into Debian via NFS, and then use gpart to create GPT partitions on the eMMC. With CONFIG_EFI_PARTITION enabled in U-Boot, I can list the partitions on eMMC as below. => mmc dev 2 switch to partitions #0, OK mmc2(part 0) is current device => mmc part Partition Map for MMC device 2 -- Partition Type: EFI Part Start LBA End LBA Name Attributes Type GUID Partition GUID 1 0x00000800 0x000407ff "boot" attrs: 0x0000000000000000 type: 21686148-6449-6e6f-744e-656564454649 guid: 6137f187-600c-4dc4-8a74-ee8f0250d455 2 0x00040800 0x002987ff "system" attrs: 0x0000000000000000 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 guid: af78282f-21b5-4324-bf7a-f460d1ae0015 3 0x00298800 0x003187ff "vendor" attrs: 0x0000000000000000 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 guid: 15830513-0195-4e86-9b2c-cd3af5e14570 4 0x00318800 0x003587ff "cache" attrs: 0x0000000000000000 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 guid: 6e909a60-606b-4c43-bbd4-f780afd97302 5 0x00358800 0x00ecbfde "data" attrs: 0x0000000000000000 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 guid: 9e79dc0b-35d9-40f0-b638-3e718362cb26 => fastboot 0 At this point, I can do 'fastboot flash system system.img' from host PC.
