nRF5340 FOTA over BLE issue

[Sufaira N]

Hi,

Iam using nRF5340 DK and nRF Connect SDK V.2.6.1.

Iam following the link

FOTA over BLE

In this one until 5th step it worked fine and while doing 6th step it is showing error
Here Iam using peripheral lbs example
Then I add MCUboot and fota over bluetooth low energy to the application and add an extra print to the main to generate a new file for dfu
Then update the firmware using device manager app and it worked
Then I tried simultaneous updates for both cores
For this I added step 6 procedures
After adding the line CONFIG_UPDATEABLE_IMAGE_NUMBER=2 it is showing the errors

failed: "Missing partitions?"
87 | #define BUILD_ASSERT(EXPR, MSG...) _Static_assert(EXPR, "" MSG)

 BUILD_ASSERT(FIXED_PARTITION_EXISTS(SLOT2_PARTITION) &&

Kindly help me to find a solution for this 

Thankyou

Hello,

Could you upload your current project here so I can try to reproduce the build error?

Thanks,

Hi,

This is my current project and while adding the line "CONFIG_UPDATEABLE_IMAGE_NUMBER=2" it is showing build errors.

Thank you

Hi,

The zip file only contained the workspace file, not your project files.

You were missing the 'child_image' directory. Please try the attached sample.

Hi,

Thanks for the reply

2146.peripheral_lbs_1.zip

After adding this also it is showing errors

error: 'PM_MCUBOOT_PRIMARY_1_ID' undeclared (first use in this function); did you mean 'PM_MCUBOOT_PRIMARY_ID'?

Please try the sample I uploaded.

Hi,

Thankyou the example code you given worked well.

1) But when I update both cores in nRF connect device manager app it is only working by giving      "Confirm only" option, other options are not working. Why these options are not working?

2) In my requirement I want to update both application core and network core . In the tutorial I have a concern that until 5th step only the application core is changing or both cores are changing?

3) I want to implement FOTA in my custom nRF5340 BLE project. Can I follow the steps in the          tutorial, or do I need to add any additional files?

Thankyou

Simultaneous multi-image DFU on the nRF53 does not support reverting images (i.e. revert back to the original FW version if the image was not confirmed). Therefore, it should not make any difference if you mark the update for 'test' or 'confirm'.

Both cores will be updated if you upload the dfu_application.zip.

The tutorial also applies to custom boards.
