Error programming Thingy 91X: slot_index_primary is required

[andersr]

I have rebuilt the sample app at_client using VS Code (Mac)
nRF Connect SDK v2.6.0 and Toolchain v2.6.0
Board target: thingy91_nrf9151
Snippets: nrf91-modem-trace-uart

I am using nRF Connect for Desktop -> Programmer v4.6.2 to program the device
File: at_client/build/zephyr/dfu_application.zip

When programming I get the following failure:
Message: Failed, Error parsing multi-image file entry: slot_index_primary is required.

Same result if I try to use command line.

Correction: build target thingy91_nrf9151_ns

[dejans]

Hi,

Are you able to build the sample from command line (with and without the snippet)?

Best regards,
Dejan

[dejans]

Hi,

Can you upload your dfu_application.zip file and provide detailed steps for reproducing your flashing error?

Best regards,
Dejan

[andersr]

I see nowhere to upload attachments. I do see the line "Attachments (0)" but no option to upload. Do you also need the file dfu_application.zip_manifest.json?

[andersr]

7127.dfu_application.zip

Following instructions on https://academy.nordicsemi.com/flash-instructions-for-the-thingy91/ for command line

Using nRFUtil Programmer:

Then selecting Write to write to Thingy flash. I get the log in original post.

Hi,

I have replicated your issue. I will look into this further. I expect to get back to you during next week.

Best regards,
Dejan

[dejans]

Hi,

It seems that you use incompatible combination of versions of newer "nrfutil device" and older Toolchain. Your "nrfutil device" expects a specific structure of manifest.json but different is used. You can either try to downgrade to an older "nrfutil device" version or you need to use newer Toolchain which has sysbuild enabled.

Best rgards,
Dejan

Updated SDK and toolchain:

I now get the following error when building at_client (all other options default):

Hi,

In your VS Code screenshot board target is specified as thingy91x/nrf9151/ns while your build command shows --board thingy91x/nrf9151. Have you built the sample as secure or non-secure?

Best regards,
Dejan

[andersr]

I just deleted build directory , set up environment as shown and pressed "Generate and Build". I deleted the build directory again, kept build configuration and did another "Generate and Build". This time the build target is correct, but I still get an error:

Deleted old at_client and started with at_client from nRF Connect SDK v3.0.2. Built successfully. Loaded on target successfully.

Deleted build directory. Added mrf91-modem-uart-trace snippet to build configuration 

Got following build error (re-build here to shorten output):

* Executing task: nRF Connect: Build: at_client/build (active)

Hi,

You can try to shorten the path to the sample project. Do you get different result?

Best regards,
Dejan
