STM32F4 “Could not be resolved” resourses on Eclipse (macOS)

Question

I have a STM32F429I-DISC1, and I generate code by STM32CubeMX and works fine. But, before this I followed some tutorial to run the codes and compiles. I`am a newbie with this. The projects worked fine, like blinks led, for example. When I go upgraded the my skill and generate other projects, I excluded the recent projects on eclipse and regenerate a other projects on CubeMX, So not more works! All resources shows "Could not be resolved". I re-followED the tutorials but not has solved. The follow prints ilustre my problem.

The curious is it, the tool settings appears be null.

Answer 1

If I can suggest something.

Remove it and install openSTM32. it is basically the eclipse + plugins + toolchain but it imports very well all the cube related project. Otherwise it is a tricky and difficult to get it compiled (too many dependencies etcetc).

it is officially supported by STM
