Firmware Upgrade Scheme using emmc in imx8mplus

[anjuv]

Do you already have A/B partitioning firmware update scheme for emmc implemented for imx8mplus boards?

Requirement

A/B system updates use two sets of partitions referred to as slots (normally slot A and slot B). The system runs from the current slot while the partitions in the unused slot are not accessed by the running system during normal operation.This approach makes updates fault resistant by keeping the unused slot as a fallback: If an error occurs during or immediately after an update, the system can rollback to the old slot and continue to have a working system. To achieve this goal, no partition used by the current slot should be updated as part of the OTA update

Hi Aldo, 

The above documentation gives the setup for imx6ull, imx8mm & imx93.

I manually made some changes to build this for imx8mplus . But I'm facing errors while running it.

So do you have the correct working patch of these repository files especially (meta-swupdate-imx & swupdate-scripts) to enable this feature on imx8mplus-evk.
