VS Code programming error

[Basri Kilic]

Hello everyone. I am trying to program nrf52832 with Zephyr. However, I am getting the error seen below. I did not understand what happened

Flashing build to 269305826
C:\Windows\system32\cmd.exe /d /s /c "west flash -d c:\ncs\Yeni\blinky\build --skip-rebuild -i 269305826 --erase"

The above exception was the direct cause of the following exception:

Hi

Thank you for contacting DevZone at NordicSemi.

1) Have you previously built and flashed any Zephyr or Nodic sample successfully in VS Code?

If yes then what you are doing different this time?
If no then I would recommend you to follow the Nordic Getting Started with NCS tutorials here

2) What is your hardware setup? Are you using Nordic DK?

How did you install the SDK? We recommend installing nrfCommand line tools and nrfConnect for Desktop and then install NCS using toolchain manager.

It will also be good if you could show the issues using the snapshot of the procedure you are following.

Regards,

Naeem

"Thank you for your feedback. I tried again today and successfully built the same example and flashed it to the nRF52."
Even though I successfully build and upload to nrf52, I still get this error
I am using the nRF52832 microcontroller and Segger J-Link.

And can you help me how to use the nRF Terminal?

[Naeem Maroof]

Please see this ticket that experienced same kind of errors.

When you click on "Terminal", you would see the process of building and flashing.

nRF Terimnal also got integrated into "Terminal" tab.

You could issue commands like "west flash" using terimnals.

Also, if you want to see console output, you would either connect to nRF Terminal or the RTT.

You could also use other terminal programs (like Putty) to see the console output.

"Thank you for your help. I understand. 
I want to drive a dc motor with PWM. But don't take any samples. There are examples of servo motors but no examples of dc motors. Can you help with this too?"

[Naeem Maroof]

I am not sure about that. Our all samples are well documents and included in SDK.

You can look into related sample and update it for your specific use-case and hardware setup.

You may also find online some code for dc motor control using other platforms and adopt accordingly.

This ticket also discusses the same.
