swupdate on Jetson Nano emmc

[harri-pm]

Hello,

I post an another question. I thought I got the update working one time with previous instructions #855 and #842. However, I am stuck with an error during update:

root@grabber-nano:/part# swupdate -e system,slot_b -H software:1.0 -i swupdate-image-grabber-grabber-nano-20211119093951.swu 
Swupdate v2021.04.0

My partition layout, image recipe and swupdate recipe are the same or similar as in the previous threads and the machine config file file seems to be the same as in the test distro, at least for the parts that I think are related to the bootloader or partitions. This is first time me working with boot loaders so could you shed some light on this error? Thanks for the answers.

Based on the TNSPEC mentioned in the error message, it looks like your Nano's FAB revision is 401. It must be a new revision of the module, and the BUP generator doesn't have an entry for it. Assuming you copied the jetson-nano-devkit-emmc.conf file from the layer as the starting point for your custom machine configuration, just add fab=401 to the TEGRA_BUPGEN_SPECS setting in that file.

Thanks again! That solved it.

It seems to boot to the old partition now, but I'll try what was done here: #842.
