Find OTA code on reboot

[qualipso]

Hello !

I try to trace the code for OTA on my kindl KT3 (heisenberg, 5.8.1).

I have followed the https://wiki.mobileread.com/wiki/Kin...ting_internals and confirm i see the same on my device.

But ota-update sometimes reboots the device to do update and then additional log appears kmsg buffer:

So maybe kernel is doing update stuff I think. I get source code from amazon page and i don't see anything. I also try find files with data that is printed above, but so far no luck. I try to show linux memory too but nothing i think

I was wondering if someone could help me find where th messy lines (autopilo_update, update_os) come from, if this was already investigated or not.

I would realy appreciate some help,

That's the updater in the initramfs' recovery-util shell, which handles non-OTA package types (which are all of 'em now, since OTA packages are forbidden since FW 5.12.x).

Nothing new here.
