Hello Jacek,

I tested the exercise now. Its working fine, I used 115200 8n1 rtscts:off configuration. May be you can compare it with the solution provided at the end.

If its working with Putty It should work with NRF Terminal. Please check COM port you have selected.

Kind Regards,

Abhijith

Hello Abhijith,

I decided to upgrade from nRF Connect SDK v1.8.0 to nRF Connect SDK v2.0.0 and this helped to resolve my problem.

I was able to successfully build and run the exercise 1 from lesson 5 (less5_exer1) and I could toggle LED 1-3 on my development board by pressing keys 1-3 on my keyboard - but only when I was using the PuTTy serial terminal.

When I tried using the Integrated nRF Terminal instead of PuTTy, I was only able to see the message:

"nRF Connect SDK Fundamentals Course. Press 1-3 on your keyboard to toggle LED 1-3 on your development kit".

But when I tried to press any of the 1-3 buttons on my keyboard, there was no toggle action on any of the LED 1-3 on my development board.

I tried both available configurations for the nRF Terminal settings, namely:

(i).115200 8n1 rtscts:off and

(ii) 115200 8n1

but the problem was still there, i.e. no toggle action was taking place on LED 1-3.

Can you advise how to overcome this problem?

Regards,

Jacek

Hello Jacek,

Did you succeed in flashing the program? Take a look at this thread in devzone where the customer was able to solve the error. It looks almost similar to your case.

Please let me know if any update is there on this issue.

Kind Regards,

Abhijith

[quote user="Menon"] I can see a folder named .vscode under your project(from the screenshot). Could you check whether its having c_cpp_properties.json.[/quote]

Any update on this. Sorry I accidentally deleted one of My reply while checking. I can produce that again if you wish to.

I am looking into it but please expect some delay from my side as we are lacking employees because of summer vacation.

Kind Regards,

Abhijith

Hello,

As advised, I downloaded the solution zip file for this exercise 1 Lesson 5 (fund_less5_exer1_solution.zip) and I did extract it in the directory: myapps\fund_less5_exer1.

I then used the option "+Add an existing application" to add this application folder to my current workspace in VS code.

I then tried to build an application for this solution but immediately the following warning/error message appeared at the bottom of the screen, as can be seen on the attached screnshot_13-July-2022: "The terminal process terminated with the exit code:2". And just above that, another error message in red: "west: error: argument <command>: invalid choice..."

Hello,

Further to the activities described in my previous message that I sent about 25 min ago, I have also followed these steps, as suggested by you:

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

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

3. There are 2 sections in this - User, Workspace.

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

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

However, when I tied to build an application , the same error message "ninja: build stopped: subcommand failed. Fatal Error." appeared again , as shown in the attached screenshot entitled: "Build stopped again due to Fatal Error 12-July-2022-PM".

Regards,

Hello,

I did rightclick on that error line and I pressed the enable squiggles button, enabling it. In response I saw additional errors added to the list of existing errors, as shown on the attached screenshot entitled: Screenshot_12-July-2022.

I then tried to build the application but after a while, the build process stopped with 33 problems listed as shown on the attached screenshot entitled: "Build stopped due to Fatal Error", followed by the message: "ninja: build stopped: subcommand failed. Fatal Error".

Hello,

The screenshot you shared in the last reply says that it's a "squiggle error" which you can rectify by:

Clicking 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 2 sections in this - User, Workspace.

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

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

I would like to know whether you are able to see this error after compilation because mostly it disappears. The files I shared in the last reply was tested, so hopefully it will work.

Kind Regards,

Abhijith

Hello,

As advised, I extracted the zip file: fund5_less5_UART.zip in the directory myapps\fund5_less5_UART and then, from the VS Code, I used the option "Add an existing application", to add this application folder to my current workspace.

I then clicked on the main.c file, located in the Explorer under: fund5_less5_UART>src>main.c and I immediately saw the first 28 lines of code of the main.c file, with 7 problems (related to #Include statements in lines 4 to 11 of the main.c file) listed at the bottom of the page. I attach a screenshot that shows these problems/errors listed at the bottom of the page,

These are similar problems that I observed while trying to build the application using the files that I extracted from the fund_less5_exer1.zip file that I attached to my last message to you.

What else could be a problem?

Hello,

It's not because of the Cmake file. It seems error is from the main source file (main.c). The screenshot you shared doesn't look like an updated main file as the exercise says. I am attaching the files for your reference.
