West and debug issue in nrf9160 feather board

[Rkidechaa]

Hello,

This is regarding the problem faced while flash and debug the nrf9160 feather,

1) Build and flash using the west 

we are using nrf 9160 feather so it has a different technique to compile and flash the code into it. 

Please check the below link for how to compile and flash the code using west.(https://docs.jaredwolff.com/nrf9160-programming-and-debugging.html)

To understand I tried to compile and flash the blinky code. and it worked properly.

(https://docs.jaredwolff.com/nrf9160-blinky-sample.html)

Then I tried to compile and flash GPS code with the same process but I got the error.

(https://docs.jaredwolff.com/nrf9160-agps-sample.html). I am enclosing the photo of the error. (file name is GPS error)

The question is I used the same process to flash both the code but got an error in the GPS code.

2) debug the code using visual code

As we are designing our firmware to load and debug the code we have to connect to visual code.

The Process is explained in the below Link. To understand the process I was using the blinky sample code.

(https://docs.jaredwolff.com/nrf9160-programming-and-debugging.html)

I followed all the steps mentioned in the documentation but at step 8 where we compile the code in visual code, I am getting an error. (Enclosed - file name is visual code error)

I don't know what needs to change to resolve the error.

Let me know if you can help me out to resolve the above error.

With Regards,

Hi Rahul,

We at Nordic do not officially support VScode or debugging in VScode, you can try the feather community also, might have more luck there. 
Another thing would be to ask the author of the VScode extension maybe.

Some questions I have tough. What debugger are you using? Do you have a j-link or a DK ?

Cant see any image.  Could you provide a new picture or a description of error codes and log.

Hi Jonathan,

I have already posted the query on the feather community. I was using nRF5340-PDK to debug the feather. (https://docs.jaredwolff.com/nrf9160-programming-and-debugging.html)

See the image of error below:

Hi Rahul,

Try to set "cortex-debug.JLinkGDBServerPath" in your VS Code settings (File -> Preferences -> Settings, use search window in the top of the settings window)

Hi Jonathon,

I never used visual code to debug any microcontroller. I do not understand where exactly you want to add path.OR else you can let me know how to debug the feather using external board with other software.

Can you be more specific ?

I am sharing the location which you mentioned and made same changes as per my understanding  but still giving me same error.

Question:

setting in launch.jason are correct ?

Hi, 

Here is a link to a similar case using GDB, look at the jason file provided there as a guide
Link: https://devzone.nordicsemi.com/f/nordic-q-a/66825/jlinkgdbserver-could-not-connect-to-target 

Here is a link to the segger wiki: https://wiki.segger.com/J-Link_Visual_Studio_Code 
and maybe take a look at this https://github.com/Marus/cortex-debug/wiki, and see the ..examples you may find useful. 


I have not tried this personally for the time being, but i will try to figure out the problem and test it myself some time.

Jonathan
