Custom board VSCode plugin and SDK connect v2.2.0

[lbe]

Hello everyone,

I am having a big problem in defining a custom board using the new VSCode plugin. 

I tried to follow a few tutorials and videos, but the ones I found are outdated (they refer to Segger and SDK V.1.5) and some of the instructions they

give are not valid anymore. I tried to

- create a completely new board using VSCode, but I got a lot of compilation errors that I do not entirely understand

- create a board by using an existing one (NRF52833_DK) as model, just changing names to the board. This compiles, but then I cannot even see a led blinking. I checked with ozone, and I can control leds, so I don't think there is an issue with the hardware

- started from different examples both from zephyr and nordic (zephyr blinky, nordic peripheral uart), but I got nothing.

Is there any official guide I can follow to solve this issue? My board is a very trivial one, and the baby step I would like to realize is to just blink the onboard leds for now....

Thanks in advance for your help!

Hi,

Did you already check this guide? https://nrfconnect.github.io/vscode-nrf-connect/guides/bd_work_with_boards.html#how-to-add-a-custom-board 

Best Regards,

Priyanka

Hello, thanks for your reply but yes, I already checked the guide and it is not helping, the device I created like this does not work as it is supposed to.

In the meanwhile, I tried with a different custom board we used for a few years featuring an nrf52840 (so we can exclude problems on the new hardware design) and I get the same issue: I am not even able to blink an led.

I read somewhere in the forum that some people are having problems with the pin reset configuration? I added this code

board_runner_args(nrfjprog "--softreset")

to the board.cmake file, but once again nothing changes. I checked with Ozone if I can control the LEDs, and this works fine, but the code does not run.
I feel like I am missing something very basic, but I couldn't figure it out so far.....

Hi,

I have inquired internally regarding this and will get back to you as soon as I get a response.

Hi,

Could you share your build log in order to understand more about the problem?

[lbe]

Hi,

thanks for looking into the issue. Please find here the build log. To be on the safe side, I created again the custom board from scratch by following the procedure in the Visual Studio Code plugin; to avoid complexities I only indicated the 3 GPIOs that control the leds in the .dts .

The behaviour is the same as before: building and flashing go well, but no led blinks. I checked for issues on the Reset pin, but apart from being disabled it has a voltage of 3.3V, so in any case it should not put the board in a weird state.
