TMS320C6747: How to reinstall the USB560v2 driver in CCS7

Part Number: TMS320C6747

Tool/software:

Hi.

TI.

I am trying to use CCS7 with USB560v2, but it is not working properly.
The following comment is displayed in Windows Device Manager:
"The digital signature of the driver required for this device cannot be verified. A recent change to your hardware or software may have installed an improperly signed or corrupted file, or it may be malicious software of unknown origin. (Code 52)"

I had some doubts about the CCS7 environment settings, so I uninstalled CCS7 and other libraries and rebuilt them.
I used the uninstaller to uninstall, but various library files remained in the folder under \TI, so I deleted them manually.

Before uninstalling, I was able to use USB560v2, so I assume some files were damaged during uninstallation.

Please let me know if there is a way to reinstall the USB560v2 driver and make it usable.

    Hello,

    What is the Windows version being used? What is the vendor of the 560v2 debug probe?

    Also please note that CCS7 is very old and unsupported. I would recommend updating the CCS version if it is possible.

    Thanks

    Hello.

    I am using Windows 10. The USB560v2 debug probe is from EWA Technologies, a Blackhark series.

    I am aware that the version is old, but I missed the timing to upgrade.

    Thanks.

    Very likely the issue is that the drivers for Blackhawk being used is very old and various security updates from Windows 10 is causing this message.

    You can try updating the Blackhawk drivers to see if that helps (using the CCS Update manager). You may be limited on how much you can update the drivers due to the old CCS version being used.

    Hello.

    Following your previous response in another thread, I tried installing the Blackhark driver from the installer again, and the problem was resolved and the USB560v2 debug probe was able to operate normally.

    The reason is unclear, but perhaps some instability occurred during the initial installation.

    By the way, the drive of the PC I am using is an SSD, so the file information may have been corrupted.

    In any case, thank you for your assistance so far.

    I have glad to hear that the reinstalling the drivers helped resolve the issue. Yes, it could have just been some bad installation of the drivers that caused some instability.

    Thank you for the update.
