IWR1843:IWR1843代码错误

Part Number: IWR1843

IWR1843代码跑到MMWave_open停止,停到的函数位置在rlDriverMsgRead()。
具体错误如下
MMWave_open (gAdcdataMSSMCB.ctrlHandle, &openCfg, NULL, &errCode)
Cortex_R4_0: 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 9.7.0.00213)
Cortex_R4_0: Trouble Removing Breakpoint with the Action "Continue or Finish Stepping" at 0x26d6: (Error -1066 @ 0x26D6) Unable to set/clear requested breakpoint. Verify that the breakpoint address is in valid memory. (Emulation package 9.7.0.00213)

是什么原因,如何解决,谢谢!
