在自己的板子上调试报错如下,demo板上调试正常:
Cortex_M3_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 8.0.903.2)Cortex_M3_0: 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 8.0.903.2)
另外还发现一个奇怪现象,用Flash Programmer 2擦除flash后,第一次调试能正常进行,但第二次调试又出现如上错误。
Viki Shi:
Flash Programmer 2进行mass erase再试试

回复 Viki Shi:
刚才进行了mass erase,但是上电后仍旧是这个现象。。

回复 Susan Yang:
问题已解决,是自己的板子负载一上去,cc1310这边就断了一下。电源芯片的响应提高,问题不再复现。
