Cannot install STM32W Composite Device

Hi,

Yesterday i have taken a STM32W RFC kit, in the user manual of RFC kit in section 1.8.2 it is given that ''To use the serial communication channel on the kit application boards, a Virtual COM port driver for STM32F103xx must be installed. This driver is provided within each RF software library package.'' I have installed virtual com port driver for stm32F103xx from st site, after installing, i connect the RFC kit, it tried to install ''STM32W Composite Device'', and it is unable to find the required file and it is saying that cannot install STM32W Composite Device. But basic communication using the talk demonstration application is working fine. Because of virtual driver problem i am unable to use stm32w_flasher utility, i dont know what could be the problem? Am i missing anything? Is any one used this? help me Thanks in Advance

Hi,

Did you tried with putting

the application board jumper P2 on position 5-6 (power via USB).

With regards, matarus

Hi matarus,

Thank you for your reply, and sorry for the delay. There is no jumper provision on the board, the problem was solved, i installed dpinst_x86.exe, now the virtual com port is working.

Hey lala.gopal_lal,

I'm currently facing the same problem like you had: installing the Virtual COM port driver for the STM32. However, installing

dpinst_x86.exe

didn't help. Which OS where you using? I'm using Windows 7. Thanks in advance.

Hi

I am not sure your problem is the same as lala.gopal_lal. They had a very specific STM32 eval board. What STM32 eval board do you have? What software are you running on it?

Three posts from a year ago, odds of a response are pretty slim.

 Hi, thanks for the fast reply!

I'm using a  STM32W MB950 board.

I'm trying to flash a contiki

http://www.contiki-os.org/

program on it with the stm32w_flasher. The board is currently not recognised by Windows 7 and is displayed as: STM32W Composite Device.

Hi

''I'm using a  STM32W MB950 board.'' Sadly, the page you referenced does not show a demo software package. The standard peripheral library http://www.st.com/web/en/catalog/tools/PF258146 may have some example code which may work without any modifications. I do not know - you will have to try. The problem is that you are starting with 2 unknowns : Host VCP driver Target USB CDC code. There is no guarantee the code at contiki is going to work. The only guaraneteed source of good working code is STMicro (as far as I am concerned). Do you have another STM32 dev board with USB and demo software from STMicro? This will allow you to prove the host VCP driver.

Hi,

I currently don't own an other ST Micro board. Like in the very first post, the manual states ''To use the serial communication channel on the kit application boards, a Virtual COM port driver for STM32F103xx must be installed. This driver is provided within each RF software library package.'' . So i tried installing the STM-studio software from the ST site (

http://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/PF251361

) and after the installation I found a folder named ''Virtual COM Port Driver'' that contains the dpinst_x86.exe file. If I'm not mistaken the problem is that tis driver is not compatible with Windows 7? Once the driver is correctly installed, then I should be able to use the STM32 in a Linux-VM with contiki and my problem would be solved. If the problem continues, I'll try to flash the board from a native Linux-host and report back my success. Thanks for the help!
