FOTA update failure for custom development

Hello,

Can you configure MCUboot to provide logging information? This will give insights into whether the new image is being validated or rejected at startup. See this step. You mentioned that the image is marked as 'test,' which means the image will be booted only once unless confirmed. If, for any reason, boot_write_img_confirmed() is not called after a successful boot, the bootloader will revert to the previous image

This can be an issue if MCUboot is looking for a specific image slot, and it doesn't exist or is improperly sized. In such cases, it might not boot the new image. Ensure that both the primary and secondary slots in the partition layout are configured properly for MCUboot.

Kind Regards,

Abhijith

Hi Menon

We are running a program in an nrf9160 but everything network related is being done on an external chip. So were using AT commands over UART to perform FOTA and everything else. My question is that when the update is downloaded everything until the reboot works perfectly. There are no obvious erros. The image type is "Test". However on reboot, nothing happens. What can i do to log what happens after the reboot. How can i tell if the update ever runs. NB: i am currently using custom partitions. Can this be a factor ?

Hello,

Which SDK version are you using? What does the log say? Are there any error messages?

Could you clarify the setup further? I'm a bit confused. The title mentions FOTA, but the image is being received via UART.

Kind Regards,
