大家好，我用CCS7.2烧写程序时出现如下错误：
红色部分的字为：
CortexR4: Error: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 6.0.628.3)
CortexR4: Trouble Halting Target CPU: (Error -2064 @ 0x0) Unable to read device status. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 6.0.628.3)
CortexR4: Unable to determine target status after 20 attempts
CortexR4: 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。
程序已经下载到TMS570上了，不过不能在线调试，上图调试界面的运行按键一直是灰的。程序是用HALCoGen生产的，测试以前用的其他工程程序没出现过这样的问题，请问这和工程设置有关吗？
