Hi members & experitses,

My IDE is Ac6 Systemworkbech:
Eclipse IDE for C/C++ Developers
Version: Neon.3 Release (4.6.3)
Build id: 20170314-1500

My platform is STM32F4-Discovery.

I developed a FreeRTOS V10.0.1 four-thread program to blink the four LEDS on the platform. But those LEDs are not blinking at all, while the problem is able to be debugged.

Following are my source code and the debugging log. I wish you would like to view them and tell me what is wrong in my programming.

Thanks,
Tommy
