Keil 5.11 st-link usb communication error

Bogdan Golab

Hi,
Just upgraded the Keil 5.10 to 5.11 to have STM32L0 support.

When trying to debug my application I get: "st-link usb communication error" and debug fails.

I have no problem connecting to my board using ST-Link Utility.

The 5.10 works fine - no issues with connecting to the ST-link.

I use the latest ST-link drivers and firmware (STLinkUSBDriver.dll v4.3.3.0, ST-LINK Firmware version : V2J21M5)

    Anyone can send in bug reports. A bug in an evaluation version will be just as important to close since
    1) People hurt by it will think twice about buying a commercial license.
    2) The bug is likely to also exist in the commercial editions.

    The only problem is that the support is likely to receive a huge number of user-error reports - and much more such reports from students using the evaluation version and lacking experience with programming.
