工程为TI例程，“epwm_ex4_configure_signal”
MCU型号为：TMS320F280049
操作1：利用XDS100V3在线仿真，连接上后，点击运行，仿真器自动断开，提示错误如下：
C28xx_CPU1: GEL Output:
Memory Map Initialization Complete
C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...
C28xx_CPU1: GEL Output: ... DCSM Initialization Done ...
C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...
C28xx_CPU1: GEL Output: ... DCSM Initialization Done ...
C28xx_CPU1: Error: (Error -1044 @ 0x0) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 9.2.0.00002)
C28xx_CPU1: Unable to determine target status after 20 attempts
C28xx_CPU1: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
操作2：利用uniflash把out文件烧进去，提示错误如下
[ERROR] IcePick_C_0: Error connecting to the target: (Error -215 @ 0x0) The semaphore for the test bus controller is in a time-out state. Unified-SCIF was unable to acquire the semaphore used to express ownership of a controller by a utility or debugger. You may have to exit other clients because the timeout occurred. (Emulation package 9.2.0.00002)
请问是什么原因导致的？
