Problem with Keil uVision 4: ''Failure loading STLinkUSBDriver.dll''

Hello,

when i try using the STM32 Discovery board (STM32F100)

with Keil uVision (V4.20.03.0, Target DLL: STLink\ST-LINKIII-KEIL.dll V1.5.6), when i try to debug or flash there always pops up this error:

''Failure loading STLinkUSBDriver.dll''.

This Dll exists in the path C:\Keil\ARM\STLink\,

but it just does not want to work.

Any help is appreciated.

Update:

i found out that the ST-LinkUpgrade.exe shows a similar problem. When

starting it, there is first this error message:

''Cant load library: ST-Link/V2 USB driver is missing''

and then after pressing ''Device connect'':

''The STLinkUSBDriver.dll file is nonexistent or in the wrong position.

Please check it''.

So i checked it, the DLL does exist, i copied it also into C:\WINDOWS\system32\,

but i does not help.

I also installed the whole stuff on another (Windows XP)-PC, but with the same problems.

Is there any Path-Variable which has to be adjusted ?

Or what else is wrong ?

I have also the same problem (with 3 PC's and 3 different STM32VL Discovery boards), and after 2 weeks to contact with ST, I don't have an answer...

Now

I

bought

an

LPCXpresso to test it and I will leave the STM32

Try to install the ST-Link Utility and check if occurs the same problem:

@skocir.simon:

Unfortunately, no :(

@pantani:

I installed the ST-Link Utility, but here an error box pops up and says:

''Unknown target connected''

I dunno..

I tried the IAR-IDE, and this just works...

Wolfram,

what is the language of your computer?

Curiously I have the same problem that you with 3 computers with WinXP-Spanish but works fine with WinXP in English.

Hello Wolfram,

copy the attached driver, rename extension to ''dll'' and paste it over the same name one in C:\Keil\ARM\STLink.

(maybe backup the original dll prior this action).

Hello JR,

thanks for the new library, but the problem remains the same.

Hey guys,

I have a solution for this. Man, this is ugly but works...

1) Download the ST-Link software um0892.zip and install it.

(

http://www.st.com/internet/com/SOFTWARE_RESOURCES/TOOL/DEVICE_PROGRAMMER/um0892.zip

)

2) Copy the DLL (STLinkUSBDriver.dll) from ''C:\Program Files\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utility'' to ''C:\Keil\ARM\STLink''.

3) That's it!!

This tool from ST was able to find my device through JTAG-USB but the Keil-MDKv4.20 wasn't. Then I had the idea to try this experience which just solved my problem.

As I said before, that's a very ugly solution!!

Regards!

Wagston.

Dear all,

To use MDK-ARM v4.20 with ST-LINK/V2 properly you need to upload the ST-LINK V2 driver fom the following link:

http://www.st.com/internet/evalboard/product/251168.jsp

- SW DRIVERS

For Win7 users, you may also need the attached STLinkUSBDriver.dll which fixed known limitation. You need jsut to overwrite the STLinkUSBDriver.dll located at: [Keil_Install_Directory]\ARM\STLink.

PS: Both ST-LINK V2 driver and the attached Dll will be integrated in the coming version of MDK-ARM by June.

Hopefully this helps.

Best Regards,

Ibtissem
