Hi! Thanks for opening up an issue for this. The linker is returning an error. The undefined referent to _exit, _kill,_getpid is standard for a new version of the arm gcc compiler, however it should not return a linker error. Could you try to reinstall the build tools (arm-none-eabi) this might resolve the issue. If not there might be another issue and if so please let me know.

I reinstall the build tools (arm-none-eabi) but it still bug

@hoanganh1911 what kind of bug are you experiencing do you have the output of the build logs in your terminal?
