LAUNCHXL-CC1352R1: CCS中Debug->System Reset錯誤

CCS: Version: 12.1.0.00007

硬體無修改(LAUCHXL-CC1352R1, chip rev E), 直接使用example, project Zero SDK:simplelink_cc13xx_cc26xx_sdk_6_30_00_84

當使用Debug->System Reset時 就會遇到下面錯誤

Cortex_M4_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 9.9.0.00040)Cortex_M4_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 9.9.0.00040)Cortex_M4_0: Unable to determine target status after 20 attempts
Cortex_M4_0: 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

Nick Sun：

您好，

您可以查看一下：dev.ti.com/…/node 中的Cannot access the DAP，一般是连线问题。

,

Hugh：

已經依照上述方法查詢過, 沒有幫助

連線應該沒有問題, 可以run, 只是不能system reset

,

Nick Sun：

您好，

您的工程编译是否成功？是否能够成功构建项目并且输出文件.out是否位于所示的目录中？

,

Hugh：

都有成功, load到板子上run也正常

,

Nick Sun：

您好，

那现在的情况就是只有debug过程会出问题，别的都没有问题。

您这边只有这一块板吗？

,

Hugh：

是低 兩塊板都是一樣的 就是在debug的system reset會出問題

Nick Sun：

您好，

根据以下资料：https://www.ti2k.com/wp-content/uploads/ti2k/DeyiSupport_Bluetooth_emu_resets.html
System Reset

This reset will typically reset the the entire device by asserting the nRESET signal. In general this signal is tied to PMIC devices that perform a warm or power on reset on the entire board. Frequently this reset disconnects the JTAG connection as the device is power cycled.

此复位是会断开 JTAG 连接。所以就会有硬件连接错误的报错。
