After the ota is done when I reboot the board it will run old image again.

Hi,

Today I found that after I OTA my board, it runs well at first. But when I reset it, it will run old image again.

Before this OTA, my board has gone through many OTAs, and this has never happened.

The difference between the previous OTA and this OTA is that the pm_static.yml in this project has been modified, resulting in a different flash map. Is that the reason?

NCS version: 1.9.1

Looking forward to your reply.

Hi,

Do you use DK or a custom board? Which chip do you use on your board?

Best regards,

Custom board. The chip is nrf52840.

Hi,

Did you reset the board immediately after performing OTA? Did the issue appear on first reset after OTA?

Apart from changes made to pm_static.yml, did you make any other changes?

Best regards,

I didn't reset my board immediately. Every time I reset my board, it doesn't boot up right away but it freezes for a while and the launches the old image(not the image I OTA).

In fact, the project of old image did not have pm_static.yml, the partition.yml is generated automatically. The project of new image has a pm_static.yml edited by myself, which makes the partition.yml different with the old one. Nothing else has changed.

Hi,

What is general structure of your application project?

What do you want to upgrade using OTA?

Best regards,
