Hello Nuno, It is better to post here the cmake files and the compilation execution.
Now looking at your first email, it seems that the function 'at_quick_exit' cannot be found by the linker. You can look at NuttX code (app and nuttx) and see where this function is and who is complaining. For a first implementation, maybe the linked library does not need the library that is causing the issue can be removed. It can be: * function not compiled during make export * function not found by cmake-generated linker rule - the order of the libraries call is important - when I did for stm32, I looked at the linker call when building standard NuttX to make the same on Cmake Hope it helps.
