Can't seem to get ST-Link to work. 

When I try to connect a custom STM32 board via CrossStudio, it shows "ST-LINK/V2 device in use" message.

Any idea what this message indicates?

  Make sure the ST-Link/V2 is not being used by another program.

  If you are using Windows, make sure the ST-LINK/V2 device driver has been installed.

  If you are using Linux, make sure you have permission to access the device.

  Hi Jon,

  I made sure there are no other programs using the ST-LINK/V2 and also updated the driver, since I am using windows. But the issue still exists.

  This is the observed behaviour: 

  1. Started CrossStudio. Opened the firmware.

  2. Clicked Target->Connect->ST Link V2

  3. On the Output window, the first time I try to connect, following messages appear: 
     Connecting 'ST-LINK/V2
     read operation failed
     
     
  4. The second time I try to connect and further on, following message appear:
     Connecting 'ST-LINK/V2
     ST-LINK/V2 device in use

  Are you using the latest version of CrossWorks and the latest version of the ST-Link/V2 firmware?
