hello_world debug problem on nrf52840dk VS Code.

[ashegheparyshun]

Hi,

I faced the exact problem nda, here. I take step just like nda did before. I unchecked "Enable debug options" as Marte Myrvold told, but still the same problem.

OS: Windows 10

SDK: v1.8.0

TNX.

Hi,

Does this happen only in VS Code?

I've to admit I'm testing on a custom board not a nRF52840DK. E73-2G4M08S1C.

In different scenarios, I tested blinky sample from nRF5 SDK for Thread and Zigbee v4.1.0 for keil, after some challenges it worked. zigbee-v4-1-examples-not-working-with-keil. Then I decided try SEGGER embedded studio. The blinky example worked, but after I tried Bluetooth examples, I failed. The exact sample I tested is "ble_app_beacon_pca10056_s140" from nRF5 SDK for Thread and Zigbee v4.1.0. After debugging it turns out it

hangs on "ble_stack_init();" line and it doesn't go further

I have to notice that non of Zephyr's examples worked whether using VS Code or SEGGER embedded studio.

I have five years of experience in embedded world. I've working experience with ST, TI, Espressif, and AtmelAVR but I'm new to Nordic microcontrollers.

Hi,

Is it possible to run a sample (any basic Zephyr sample) on your board, and then attach the error log that you get?

[ashegheparyshun]

After compiling "blinky" sample I got these errors.

[Priyanka]

Hi,

Could you share what you enter while 'Creating the application' and also in 'Build Configuration'?

Hi,

I captured my screen.

Hi,

From you screen recording, I can see that in your build configuration, the board specification you give are nrf52840dk_nrf52840, but you had mentioned earlier that you were using a custom board.

Also, could you try changing your "Application Location" path to somewhere inside C:\Users\Naser\ncs ?

Regards,

Priyanka

[ashegheparyshun]

Hi,

Yes, as my module and nrf52840dk using the same SoC, why should I give another board specification? The led0 pin (P0.13) is available on custom board and I use it as debugging purpose.

I also gave board specification nrf52840dongle and it didn't work too.

About the  "Application Location" path, I tried what you said and it didn't work.

This is my screen recording:

This is the output from the "Terminal" tab:

I'm totally frustrated. I'm purchasing a nrf52840dk. Although the "blinky" project worked in Keil, but maybe there is a problem with my hardware/Jlink.

Hi,

I am really sorry that you are facing such an issue and I understand that it can be frustrating. We can try to find a solution. 

Even though both your custom board and the nrf52840DK have the same SoC, there are other pins on the boards and their configurations can be different from your board. As for dongle, the dongle has it's own firmware and in order to flash a new firmware you will have to hard reset the dongle.

But on the bright side, in your screen recording, I can now see that the problems that you have are related to "error squiggles" and in order to rectify this, you have to click on that error and press the enable squiggles option, OR if this doesn't work,

1. Press Ctrl+ (comma) which will take you to the settings page.

2. type in "error squiggles" in the search bar.

3. There are 3 sections in this - User, Workspace, firstapp. 

    In the User section, under 'Error Squiggles' , select " EnabledIfIncludesResolve " 

    In the Workspace section,  under 'Error Squiggles' , select " Disabled" 

But still, I would suggest you to try this on a nRF52840DDK. Kindly try these and let me know how this goes.

Regards,

Priyanka

Hi again,

You Nordic guys are very kind and supportive.

These errors go after compilation. But I've noticed If I try to open <zephyr.h> it won't work. This happens for <devicetree.h> also. I have to say that I'm using VS Code to create application for windows, maybe a conflict in configuration. (Although it didn't work with SEGGER embedded studio either). 

I have to purchase the nRF52840DK from China. These guys are in they're holidays .

Would you please send me two hex file base on Zephyr RTOS?

One for toggling LED on P0.06 (just like nrf52840dongle) . And the other one, just a simple Bluetooth broadcaster.

At least I can verify the hardware setup. I'll flash these hex files using J-flash.
