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.
