FOTA Firmware is not kept after Reset

[danielboe]

Hi,

Today I realized something interesting for our devices: The Update from an older Software Version build with SDK 1.6.X was on it and I updated via AWS FOTA to new version build with some changes and SDK 1.7.0 . The Update works fine and the firmware works perfect. The Image gets also confirmed via boot_write_img_confirmed();

After reset the device waits some time (like it does after the reboot after OTA) and then it starts again the old Image. I dont know how I can debug because it is always described that "boot_write_img_confirmed();" keeps the current image. 

What can be the reason for this?

Thanks and best regards

Hi Daniel,

I did a quick check, there is no issue on my side when I FOTA NCS v1.6.1 to NCS v1.7.0 nrf9106/http_update/application_update sample. Just share my log with you. I added "printk("Current APP version:%d\n",CONFIG_APPLICATION_VERSION);" to make it easy to find the version change.

can also other settings changes in prj.conf cause this issue? I will investigate more tomorrow and share the data
