SDK v2.0.0 Asset_Tracker_v2 does not run on nRF9160DK with older default version.

[rdauben]

We received the nRF9160DK that included default firmware for the Asset Tracker v2.  The default version appears to be an older version of the application.

We built the latest version of Asset Tracker v2 from the nRF Connect SDK v2.0.0.  The build is successful.  When we flash it to the nRF9160DK, we are required to do a full erase because of UICR changes.  Upon reset, we see the bootloader logs, then it attempts to jump to the first image slot, but it does not run after that.  The startup log is shown below.

Are we missing something to set or clear a security issue that is left over from the previous version?

Hello,

I got feedback from our team. You can set CONFIG_FPROTECT=n in both b0 and MCUBoot during debugging only. 

Thanks.

Best Regards,

Kazi Afroza Sultana

[rdauben]

Can you please provide more details about how to make these changes in the build?

I manually set CONFIG_FPROTECT=y in these 2 files:

• build_dbg\b0\zephyr\.config
• build_dbg\mcuboot\zephyr\.config

The build failed with an error:

__main__.PartitionError: Conflicting configuration found ...

The full build log is shown below.

Thanks.

Ron

Hello,

I have got feedback from my team. You can not modify the .config file. This option should be set in prj.conf. So, in the child_image folder you should create b0.conf and mcuboot.conf file where CONFIG_PROTECT = n. 

Thanks. 

Best Regards,

Kazi Afroza Sultana

Thanks for the clarification. I created the config files you advised and set "CONFIG_FPROTECT=n" in both. The configuration process completes now, but the build fails with this undefined symbol:

C:\Nordic\v2.0.0\nrf\samples\bootloader\src\main.c:83: undefined reference to `fprotect_area'

Thanks.
