Boot sequence in Jetpack 6

HI all,
I’d like to get some detailed explanation about the Jetpack boot order Orin
I’d like to understand the

  1. role of each and every partition in the system
  2. Where is their source code, if any
  3. How do I work with encryption
  4. How can I update all the partitions and not only the kernel and dtb partitions
  5. How do I tell the board to boot from QSPI of NVME
    Thanks

Please study Boot Architecture — NVIDIA Jetson Linux Developer Guide 1 documentation

I did, there a r ea ;pt of elements missing

May I know what is missing?

For question 2, all source code that is released to public could be found on this website.

  1. How do I work with encryption

What encryption? Disk encryption?

  1. How can I update all the partitions and not only the kernel and dtb partitions

Doing a full flash will do this work. And every new user should learn how to do full flash.

  1. How do I tell the board to boot from QSPI of NVME

It seems not a correct question. QSPI and NVMe is not a either-or option. QSPI has bootloader software while NVMe only has data. If your system is booting from NVMe drive then it must have QSPI boot too.

I’d like to know how are the bootloader / uefi files are burnt in the storage. I’d like to be able to do the same from the SOM itself, without using the RCM procedure
Are the executable needed available?
To make it short, I’d like to be able to update all the files on the board from a remote or a USB pen

Thanks.
3. I meant using fuse and disk encryption
4. I was meaning doing this from the device itself, without using the RCM flow
5. Right you are. So, what exactly goes to SPI and what to NVME, and how do I burn the SPI from the board and not using RCM flow

This is actually more like “OTA update” here if it is happened on board. However, if you are talking about the OS is not up and you want to reflash it from the device itself, then there is no such thing.

For fuse and disk encryption, the document shared by Kay has such info. It is doc has lots of info, you could search you need on the left side search bar.
