I cant use the "high-level" api functions, only the Low-Level (LL) functions are recognized.
If I'm switchting to the normal functions I'm getting the following errors. Am I missing out on something?

It works as intended. You can only use "high-level" api functions if you provide your own as specified in thread api and sleep.
You would also have to modify CMakeLists.txt to take proper files containiner "high-level" api functions and remove the current FreeRTOS thread api and sleep implementation (which does basically nothing and will give you error message if you try to use high-level functions without fixing it).

@Darkenkade42 Thanks for your response. Is there any sample where I could look at? Im quite new to this. Thanks in advance.
