TI ROTS BIOS设置semaphore函数错误

如何解决TI ROTS BIOS设置semaphore函数错误

运行下面的代码时，我总是收到错误消息。 这应该是示例代码，所以我不确定为什么此代码会出现此错误。

它与semaphore（）有关，但老实说，我不知道此错误来自何处。 有人可以帮我吗？

// Project: Blink TM4C BIOS Using Hwi (STARTER)
// Author: Eric Wilbur
// Date: June 2014
//
// Note: The function call TimerIntClear(TIMER2_BASE,TIMER_TIMA_TIMEOUT) HAS
//       to be in the ISR. This fxn clears the TIMER's interrupt flag coming
//       from the peripheral - it does NOT clear the CPU interrupt flag - that
//       is done by hardware. The author struggled figuring this part out - hence
//       the note. And,in the Swi lab,this fxn must be placed in the
//       Timer_ISR fxn because it will be the new ISR.
//
// Follow these steps to create this project in CCSv6.0:
// 1. Project -> New CCS Project
// 2. Select Template:
//    - TI-RTOS for Tiva-C -> Driver Examples -> EK-TM4C123 LP -> Example Projects ->
//      Empty Project
//    - Empty Project contains full instrumentation (UIA,RTOS Analyzer) and
//      paths set up for the TI-RTOS version of MSP430Ware
// 3. Delete the following files:
//    - Board.h,empty.c,EK_TM4C123GXL.c/h,empty_readme.txt
// 4. Add main.c from TI-RTOS Workshop Solution file for this lab
// 5. Edit empty.cfg as needed (to add/subtract) BIOS services,delete given Task
// 6. Build,load,run...
