Hello :)

After not beeing successful to use Crossworks for ARM with Linux I tried it with Windows 8.1.
So I downloaded and installed ST-Link-V2 drivers  for windows 8 (it's a STM32F4Discovery board).
Then I tried to connect to the target but there was always "DEV_NO_ERR"..
Target is set to SWD as it should be...
Then I installed st-link utility which works fine. But crossworks still gives me that error :(

What can I do to get it running??

Thanks so much for answers!

Florian

  Hello,

  I have the same error with 2.3.5 studio and hw STM32F429I DISCO. I works vith the DISCO board, but when I use it as ST-LINK V2, it connects the targets via SWD (I have used more electronics with STM32F101VC) but show the error DEV_NO_ERR when I try download and run rebuild project. The output window show "Preparing target for download, Executing script FLASHReset()".

  I have normaly worked project with Wiggler 20 and I have just tried to use ST-LINK V2. So I do know what do you mean "STM32 project loaded".

  When I have upgraded the win xp drivers it shows "ST-LINK/V2 device not found" although the device is connected - in the targets window it's connected and in properties of ST-LINK is device type "Cortex-M3 r1p1".

  Do you have any ideas what's wrong?

  Thanks a lot

  Robert
