Fail to launch STLINK debugger

Hi.

Its been so long since my last project with STM32, and I have created a new C project with SW4STM32 for my stm32vl discovery board and when I try to run the debugger, I get the following error.

Error in final launch sequence

Failed to execute MI command:

-target-select remote localhost:3333

Error message from debugger back end:

localhost:3333: The system tried to join a drive to a directory on a joined drive.

localhost:3333: The system tried to join a drive to a directory on a joined drive.

I’ve noticed there isnt a default template for this kit so I created a new custom board when prompted by the wizard, so I’m wondering is this my problem, how do I start the debugger.

My other board is a nucleo, and when I create new projects I just use the default template wizard, fill in the details, and the debugger starts every time.

Martin.

The VL Discovery uses the original ST-LINK V1, this might impeded usage with software expecting newer models.

Thanks clive1, I've come across that before, and actually I have upgraded this board a while ago.

But you answer has prompted a question whether I selected the correct STLINK. The options are ST-LinkV2, ST-LinkV2-1, I think I selected ST-LinkV2.

Which one is the correct selection for the discovery board?

Aso I noticed there is a ''stm32vl_discovery.cfg'' file in my project root directory, I recall this is a debug config file, is that correct?

Hi b.m.002,

In

http://www.st.com/content/ccc/resource/technical/document/user_manual/group0/d0/f7/45/d7/3b/96/47/b3/DM00285842/files/DM00285842.pdf/jcr:content/translations/en.DM00285842.pdf

, you have the following information:

''The SW4STM32 does not support ST-LINK. Consequently, STM32VLDISCOVERY can not be used with SW4STM32 software toolchain''.

Thanks Mayla. I thought I read most docs on this board, but just goes to show, read the fine print.
