osThreadDef(Funct, osPriorityNormal, 1, 256);
Waking a thread every 1ms is pretty harsh. Try every 50ms and increment count by 50.
I can say that you have two threads nakedly accessing the same variable. That access is not thread safe,
First, the variable should use the keyword ''volatile''
second, there should be a mutex that each thread calls to gain access to the variable. Only one thread at a time can ''hold'' the variable, to read or modify and then, the thread releases the mutex.
NOTE: in this simple example it might not matter to much, since one thread is the consumer and the other thread is the provider. But naked access will cause problems.
