Always run old firmware after OTA after changing flash size

[666]

HI ALL,

nrf54l15dk,v2.8.0,peripheral_uart demo and no changes have been made.

Then add the following content to prj.conf

sysbuild.conf

mcuboot.conf

At this point, OTA can run normally. If the following content is added,

OTA will only run the old firmware and cannot upgrade to the new firmware.

Do you have any suggestions？

Looking forward to your reply！

Have you pressed "confirm" button after the firmware download done?

I don't quite understand what you mean by 'confirm', but if I press the first button or the third button in the picture, it will still run the old firmware after expanding the flash

Did you update your firmware via "Device Manager" app on your mobile?

nrf connect,Then click on the top right corner

I advice you to use Device Manager app ,after downloading new firmware,press "Confirm",then the new fw will take effect after the next time reboot.
