Problems with Exercise 1 , Lesson 5 of the DevAcademy "nRF Connect SDK fundamentals" course

[Jacek Majda]

Good day,

I did follow the usual steps of this an exercise, namely:

1. I did download the base exercise project contained in the zip file: fund_less5_exer1.zip (I attach a copy of this file)

2. I did extract this zip file in my exercise folder that I use with this course.

3. I followed all the steps 1 to 9.3 of this exercise but I was unable to build  the application.

The following 5 errors related to the #include statements in lines 4,5,6,7 and 10 in the src/main.c file were listed, as shown in the attached file: "Errors_10-July-2022"

line 4: #include <zephyr.h>

line5: #include <device.h>

line6: #include <devicetree.h>

line7: #include # <drivers/gpio.h>

line 10: #include <drivers/uart.h>

Upon investigation I noticed that line 3 in the CMakeLists.txt file for this exercise differs from a similar line in the CMakeLists.txt file in the previous exercises of this course, as far as the "cmake_minimum_required" is concerned.

For Lesson5_Exercise1 the line 3 of CMakeLists.txt file reads: cmake_minimum_required(VERSION 3.20.0) while for the previous exercises line 3 of the CMakeLists.txt file reads: cmake_minimum_required(VERSION 3.13.1).

Could this be the root of the problem?  If so, how to rectify it?

Regards,

JM

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..."

Regards,

JM

I can see a folder named .vscode under your project(from the screenshot). Could you check whether its having c_cpp_properties.json.

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,

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,

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
