正在使用的DRV8301-LS12电机套件，断点调试过程中出现错误：
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 5.1.450.0)
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
CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0
使用其他工程仍出现上述错误，断电重启不起作用。
