Part Number: CC2340R5
Other Parts Discussed in Thread: UNIFLASH, , SYSCONFIG

Tool/software:

使用simplelink_lowpower_f3_sdk_8_10_01_02版本的SDK，导入nvsinternal示例程序，如下Enable 'Arm Hex Utility'配置生成hex

通过UniFlash 8.7.0下载到LP-EM-CC2340R5 LaunchPad

下载程序以后程序不运行，再次适用XDS110连接的时候报错如下，

Error connecting to the target: (Error -261 @ 0x0) Invalid response was received from the XDS110. (Emulation package 9.12.0.00150) 

且所有相关的软件都不能正常识别到芯片了

现在导致LaunchPad无法正常使用了，怎么样才能将LaunchPad恢复正常呢

    There is an issue with the LP-XDS110ET (or other XDS110 debugger) connection to the LP-EM-CC2340R5.  Please make sure that it is not in use with any other software on your computer, and verify whether you're able to program in CCS with an unmodified TI example.  Hopefully the CCFG configuration has not been changed in SysConfig to remove JTAG or bootloader access.  You should be using the following Project Properties -> CCS Build -> Steps -> Post-build steps instead of the Arm Hex Utility:

    ${CG_TOOL_ROOT}/bin/tiarmobjcopy -O ihex ${BuildArtifactFileName} ${BuildArtifactFileBaseName}.hex

    This E2E post may be removed since it is primarily written in a language other than English.  If re-posting or responding, please translate to English first.
