sequential basic 512 0 8 0 **Required.** Contains protective MBR. sequential basic 19968 0 8 0 **Required.** Contains primary GPT of the `nvme` device. All partitions defined after this entry are configured in the kernel, and are accessible by standard partition tools such as gdisk and parted. sequential basic APPSIZE 0 0x8 4096 0 APPFILE APPUUID **Required.** Contains the rootfs. This partition must be defined after `primary_GPT` so that it can be accessed as the fixed known special device `/dev/nvme0n1p1`. sequential basic 67108864 0 8 0 LNXFILE **Required.** Chain A; contains boot.img (kernel, initrd, etc) which is loaded in when cpu-bootloader failes to launch the kernel from the rootfs at `/boot`. sequential basic 458752 0 8 0 DTB_FILE **Required.** Chain A; contains kernel device tree blob. sequential basic 33554432 0 8 0 **Required.** Reserved space for chain A on user device. sequential basic 67108864 0 8 0 LNXFILE **Required.** Chain B; contains boot.img (kernel, initrd, etc) which is loaded in when cpu-bootloader failes to launch the kernel from the rootfs at `/boot`. sequential basic 458752 0 8 0 DTB_FILE **Required.** Chain B; contains kernel device tree blob. sequential basic 33554432 0 8 0 **Required.** Reserved space for chain B on user device. sequential basic RECSIZE 0 8 0 RECFILE **Required.** Contains recovery image. sequential basic 524288 0 8 0 RECDTB-FILE **Required.** Contains recovery DTB image. sequential basic RECROOTFSSIZE 0 0x8 0 **Optional.** Reserved for future use by the recovery filesystem; removable. sequential basic 67108864 0 0x8 0 ESP_FILE C12A7328-F81F-11D2-BA4B-00A0C93EC93B **Required.** EFI system partition with L4T Launcher. sequential basic RECSIZE 0 8 0 **Required.** For fail-safe recovery update. sequential basic 524288 0 8 0 **Required.** For fail-safe recovery DTB update. sequential basic 67108864 0 0x8 0 **Required.** EFI system partition for fail-safe ESP update. sequential basic 18432 0 0x808 0 **Required.** Automatically takes all remaining space on the device except that occupied by the `secondary_gpt` partition. Allocation attribute must be set to 0x808. May be mounted and used to store user data. sequential basic 0xFFFFFFFFFFFFFFFF 0 8 0 **Required.** Contains secondary GPT of the `sdcard` device.
