Hi, have got a "

ST-LINK/V2 device not found

" when trying to connect with a STM32VL Discovery board.  I have edited the project debugger properties and set it to SWD and also set the use reset thing to No.  But I cannot connect to the target board?  Any ideas? So Frustrated!

Thanks

  I think the STM32VL Discovery Board has an original STLink on it. This requires STLinkUSBDriver.dll - an ST supplied file that is/was windows only.

  If I disconnect the st-link and hook up the cross connect and swd board it should work?

  Not something I've tried - do a web search to see if anyone has used an external jtag cable on this board.

  What would be a good Arm board like the discovery series which will work with cross connect and SWD board out of the box?  Would save me a lot of messing about!

  Any other ST board with the STLink/V2 is a good target - but they don't have external debug connectors. Most of the other manufacturers have both an onboard debug capability and an external debug connector.

  Does the debugger identify the target?
