It seems that reimporting my project created a new Project in Segger called "Project zephyr/merged.hex". Now everything runs flawlessly. It appears that you were right, and that was the issue 🙂
Thanks!

Hi,

Which board are you configuring your project for? I used nrf9160dk_nrf9160ns for my test.

[quote user="Nevera"]I'm pretty sure I'm entirely missing a whole bunch of stuff in here. I'm not sure where this merged.hex file comes from, or what I'm supposed to do in "Target -> Download File". The prompt opened is expecting me to give it a hex file, but I have no idea where from.[/quote]

When building for the non-secure region (nrf9160dk_nrf9160ns), you will trigger a multi-image build, as the secure region will be populated with the "spm" (secure partition manager), and non-secure with your actual example.

Its important that you configure your project to be non-secure if you're communicating with the modem, as it can only work in non-secure mode.

Once you have build your project, in case its a multi-build, a merged.hex is available in my-build-folder/zephyr/merged.hex. This will then include all images in the multi-image build (if used)

[quote user="Nevera"]I followed a bunch of guides a while back, and I have no idea what I've removed/added/changed.[/quote]

In your project, there a build folder, typically named "build_whateverboardname". Try deleting this folder, and re-importing your project in SES NordicEdition, to ensure you're starting from scratch.

Kind regards,

Håkon

Hi Håkon,

Ok, I think I'm missing something here.

I'm pretty sure I'm entirely missing a whole bunch of stuff in here. I'm not sure where this merged.hex file comes from, or what I'm supposed to do in "Target -> Download File". The prompt opened is expecting me to give it a hex file, but I have no idea where from.

I followed a bunch of guides a while back, and I have no idea what I've removed/added/changed.

Sorry to be so difficult, I'm just really struggling to understand.

Thanks

Hi,

I suspect this is because SES-NordicEdition flashes only the application, while you actually have a multi-image setup, where you should download the merged.hex file.

You can specify the file under "Target -> Download file".

Or you can use the Programmer application in nrf for desktop to program the merged.hex manually.

A third option: you can use nrfjprog, which you can install from the nRF command line tools:

https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Command-Line-Tools/Download

path/to/nrfjprog --program <merged.hex location> -f nrf91 --sectorerase

Could you try this and see if you get any output in RTT viewer?

Kind regards,

Håkon

To provide a little more insight, the "Unknown function" error occurs when I click the green play button in Segger after running Build & Run.

Regardless, nothing shows in the RTT Viewer.

Hi Håkon,

I've erased the nrf91 using the nRF Connect programmer. I'm able to establish a connection using JLink RTT Viewer with the same connection settings as you, but the unknown function error remains.

If the command line part is important, could you clarify that a little? nrfjprog isn't defined in Bash/PowerShell/CMD (windows). I've seen where it is in the west_commands folder, but attempting to run it with python doesn't succeed either.

I'll try running it in the hello world sample like you have next and see if theres something else going on.

Thanks!

Hi,

I took your sample src, and prj.conf, and pasted it into the "hello_world" sample.

When opening JLinkRTTViewer, it shows the log:

[quote user=""]I run into `Unknown function at 0xFFFFFFFE`.[/quote]

Could you try to erase the device, then program it again? This can be done via "nrfjprog -e -f nrf91" from the command line.

[quote user=""]I'm under the impression that by default, the device logs to LTE Link Monitor.[/quote]

This is true for UART devices, but there's currently no RTT support, unfortunately. For RTT, you have to use JLink RTT Viewer.

This is my configuration when opening the session:

Could you try this and see if it runs?

Kind regards,
