IWR1843BOOST: IWR1843BOOST - USB not Showing up anymore

Part Number: IWR1843BOOST
Other Parts Discussed in Thread: UNIFLASH, CODECOMPOSER

Tool/software:

Hello,

I am having a hard time getting my evaluation board IWR1843BOOSt to run.

I am using Windows 11 and I try to follow the following guide: https://dev.ti.com/tirex/explore/content/radar_toolbox_2_20_00_05/tools/studio_cli/docs/mmWaveStudio_CLI_Getting_Started_Guide.html

I had a lot of trouble, since Uniflash is not working and prevoiusly the device didn't even show up. After installing Codecomposer Studio and updating the device drivers I had the 2 COM ports showing up.

Then I tried to flash mmwave_Studio_cli-xwr18xx.bin with uniflash but this gave me alwayr and error.

I then tried to use the following command line command:

.\xdsdfu.exe -f C:\ti\radar_toolbox_2_20_00_05\tools\studio_cli\prebuilt_binaries\mmwave_Studio_cli_xwr18xx.bin

After executing this command the 2 COM Ports were gone from the device manager but a " Tiva Device Firmware Update" Device showed up.

I was trying to get the "old" state back then but failed (following command was used):

.\xdsdfu.exe -f C:\ti\ccs1280\ccs\ccs_base\common\uscif\xds110\boot_loader.bin

In between I repowered my device.

Now it doesn't show up at all anymore. Did I brick it? Any help would be highly appreciated.

Thank you in advance!
