Hi @Bela
I would like to apologize for the delay, we are experiencing a high volume of questions these days. I really appreciate your patience.
Regarding your issue, my suggestion is to import a SDK example like 'hello world' or 'led blinky', build the project and once there is no errors, then you can start developing your code.
To import a SDK example, you must go to the quick start panel 'import SDK example', select your dev. board, click on next and then you select the project to import and click finish. I will attach a couple of images as a guide.


Hope this was helpful, please let me know if you have more questions.
Best Regards.
Pablo Avalos.
