Hi,
I work on a project that required a sector in flash to store some information hence I changed the partition in the pm_static.yml file and the dts file (although I guess this has no effect when using MCUboot).
The problems I have encountered is the following:
- Flashing a firmware (A) that uses the new partition, it is not possible to downgrade to a firmware (B) using the old partition. The downgrade is succesful but the system reboots after a few seconds and reverts the image back to (A).
- Flashing a firmware (B) that uses the old partition, it is possible to upgrade and stay on a firmware (A) that uses the new partition. Doing another upgrade to a firmware (C) that uses the same "new" partition reverts the image back to firmware (A).
I'm calling boot_write_img_confirmed at startup and has not seen any firmware reverts before changing the partition.
