Fota anomaly based on Ncs 1.9.0 sdk

[duxinglang]

I developed a product for the customer with 9160. It used to run on the sdk of ncs1.2.0, and its fota function is normal; Now I have upgraded the sdk to ncs1.9.0, and found that the fota function is abnormal. The device can connect to the background and download apps normally_ update. The bin data is written to the img. After the writing, the device is restarted, but the device still runs the old firmware instead of the new one. Why? This is my prj.con and logs show:

Hello,

Could it be that the memory layout has changed between these versions? For DFU to work, it is important that the primary and secondary slot partitions remain at the same addresses between updates. The normal way we ensure this is to use a startic partition file as explained here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.2/nrf/scripts/partition_manager/partition_manager.html#configuring-static-partitions.

You can for instance make a copy of the partitions.yml file from your v1.2.0 project and use it as a static partitions file in your new project.

Best regards,

Vidar

Thanks for your reply. My current operation is to create an app on ncs1.9.0_ update. Bin, and then modified the interface to compile and burn it to the device. That is to say, when testing, the old firmware of the device and the new firmware of FOTA are compiled on ncs1.9.0, which should have nothing to do with slot partitions. Later, I found out that if Add CONFIG to conf_ BSD_ LIBRARY_ SYS_ INIT=n, after compiling and burning, my device will switch to the new firmware that was fota last time after it is powered on again, but it cannot operate the modem. It is strange whether the modem is turned on or off. By the way, the firmware version of my modem is v1.3.1.

[Vidar Berg]

What SDK version are you building the app with now? I read it as being 1.9.0, but this version does not define the CONFIG_BSD_LIBRARY_SYS_INIT symbol (BSD lib was renamed to modem lib in v1.5.0), so I don't understand how you can still use this symbol and build your project.

[duxinglang]

Sorry， I made a mistake. It is the CONFIG_NRF_MODEM_ IB_SYS_INIT.

[Vidar Berg]

OK, thanks for confirming. Could you try to initialize the modem library yourself from main(),etc and see if it works then (i.e. both DFU and modem lib).

[duxinglang]

OK.This is my initialization code:

#ifdef CONFIG_IMU_SUPPORT	
	k_work_q_start(&imu_work_q, imu_stack_area,
					K_THREAD_STACK_SIZEOF(imu_stack_area),
					CONFIG_APPLICATION_WORKQUEUE_PRIORITY);
#endif

Based on what you describe, it seems as if the boot_write_img_confirmed() function only works when called before modem init.

Please check the return code from boot_write_img_confirmed(); and see if it returns with an error when  CONFIG_NRF_MODEM_ LIB_SYS_INIT=y.
