SWUPDATE to update a generic RaspberryPi OS

[Praful Kabadi]

Hi All,

I saw couple of articles on the forum where in swupdate is being used on RaspberryPi via meta-sw update layer using Yocto Image.

I wanted to know if anyone have tried to update the same on a Raspberry Pi using the generic Raspberry Pi OS (Build root system) built using the Raspbian Buster.  

If yes, could anyone point at the articles / resources that could come handy?

Thanks :

I read in the beginning that SWUPDATE supports UBOOT, GRUB and EFI Boot Guard in the overview page and while reading another article I came across an article that says Raspberry Pi 4 with the latest Raspberry Pi OS ( based on Debian 11 armhf architecture) does not use it by default. Just wanted to therefore clarify if using SWUPDATE for the OTA update of the same was possible.

Yes, it is possible, but kernel should be loaded by U-Boot instead of
the Broadcom's bootloader. That means that in the FAT partition, U-Boot
replaces the Kernel. Take Yocto's implementation in meta-swupdate-boards
as reference.

Hi  Praful, have you had any luck in implementing the SWUpdate on Buster?

Kind regards
