  • in device manager, I can see "STMicro electronics STlink virtual com"
    and I can see a serial number of the board before download program on board but when I click on download, it shows the above error. i download stsw-link009 and install it, but it doesn't work. but now I open Keil and target manger, i give this message "old st-link firmware detect ..." and I click yes to upgrade the firmware but it can't update and download program
