This is a sample GPT partition layout for SD card, right now three important partitions are added to make the system bootable.
partition layout:
Part Start LBA End LBA Name Attributes Type GUID Partition GUID 1 0x00000022 0x00000821 "loader1" attrs: 0x0000000000000000 type: 5b193300-fc78-40cd-8002-e86c45580b47 guid: cbcbef44-e627-42bc-b134-93b6f3784b8c 2 0x00000822 0x00002821 "loader2" attrs: 0x0000000000000000 type: 2e54b353-1271-4842-806f-e436d6af6985 guid: f54eba28-d8de-4852-978d-1a673777e2ae 3 0x00002822 0x00020821 "rootfs" attrs: 0x0000000000000004 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 type: linux guid: 9561df46-8d55-4799-a83b-cfee9ef6ff93
Note: - loader1 would be fsbl or spl - loader2 would be U-Boot or U-Boot proper
