1.Boot partitions, which are used in the boot process, and are visible only to Bootloader. Many of the boot partitions have redundant copy partitions. The copy partitions must have the same names as their primaries with the suffix ‘‑1’. For example, the NVC partition’s copy must be named NVC‑1. The boot partitions are: •BCT, which contains redundant instances of the Boot Configuration Table. This must be the first partition on the boot device. •NVC contains TegraBoot. This must be the second boot partition. The following boot partitions, PT through SPF, are part of the BFS. •PT contains layout information for each BFS, and indicates the beginning of each one. It is the first partition in the BFS. •TBC contains the TegraBoot CPU-side binary. •RP1 contains TegraBoot DTBs. •EBT contains CBoot. •WB0 contains the warm boot binary. •BPF contains BPMP microcode. •NVC‑1 contains a copy of NVC. •PT‑1 through BPF‑1 are copy partitions for the primaries NVC through BPF, making up a copy of the BFS, denoted BFS‑1. •PAD is an empty partition which ensures the VER and VER_b are at the very end of the boot partition. •VER_b contains additional version information for redundancy and version checking. •VER contains version information. 2.GP1 contains the sdmmc_user device’s primary GPT. All partitions defined after this one are configured in the Linux kernel, and are accessible by standard partition tools such as gdisk and parted. 3.User partitions, which have a variety of uses. Some of them may be deleted, and/or may be mounted and used to store application files. The following partitions constitute the kernel-file-set (KFS), and have redundant copy partitions: •DTB contains kernel DTBs. •TOS contains the trusted OS binary. •EKS is optional, and is reserved for future use. •LNX contains either the Linux kernel or U-Boot, depending on your choice of DFLT_KERNEL_IMAGE in the configuration file. •DTB‑1 through EKS‑1 constitute a copy of the primary KFS, denoted KFS‑1. •Other partitions, such as APP and BMP, are outside the scope of this document. For information about these partitions, see the appropriate subsection for your Jetson platform in Default Partition Overview. Kernel-file-set (KFS)

Have you made any changes to device tree? If not, then likely you will need to reflash the unit (NvTboot is a very early stage in boot, long before Linux is ever reached). If you have an SD card for rootfs you could save a copy of that. Note that where some of this content is found differs between QSPI memory and the SD card depending on release. I can’t say much more which is useful, but if you do need more help, then knowing the release used on this unit and any flash history would help whoever answers.
