TPS6594x芯片使用Scalable PMIC GUI时,调试器MSP-EXP432E401Y的连接问题

Other Parts Discussed in Thread: MSP-EXP432E401Y

想使用TI官网购买的调试器MSP-EXP432E401Y,配合Scalable PMIC GUI工具,来调试PMIC芯片TPS6594X.

使用电脑的usb接口连接好MSP-EXP432E401Y(此时电脑设备管理器已经显示多出两个COM口),打开Scalable PMIC GUI工具并点击quick start,提示“

Update Firmware
The device is using firmware version undefined.undefined.undefined.undefined. Recommended firmware version is 1.0.3.5.
  • Step 1: UPDATE Firmware
  • Step 2: After firmware update succeeds, please unplug and re-plug the device, and click Finish

点击"UPDATA",后会报错“Update  failed”。重复很多次都不行。

请问该如何将firmware升级到正确的版本“1.0.3.5”?
