Hello everyone,

I'm trying to use the osSemaphoreCreate as it follows:

const osSemaphoreDef_t* semaphoreApp;
osSemaphoreId semaphorID;

semaphorID = osSemaphoreCreate(semaphoreApp, 0xFFFF);


But everytime I run this code, it gets stuck in an infinity loop, is there any example of a correct implementation?

Best regards
Alan
