Hi med_yassine.jebabli,

1-As I read in the last post of this

https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Java/Flat.aspx?RootFolder=https%3a//my.st.com/public/STe2ecommunities/mcu/Lists/STM32Java/stm32f429%20Discovery%20vcp%20with%20STM32CubeMX%20drivers&FolderCTID=0x01200200770978C69A1141439FE559EB459D758000F9A0E3A95BA69146A17C2E80209ADC21&curren...

you have followed, the user set the heap size to 0x400, but our moderator

has mentioned the value of 0x4000. So, try this solution.

2-Try toload a project ''CDC_Standalone'' from the package STM32Cube_FW_F4_V1.8.0 on your board, the heap size in it is 0x1500. By consequence, if this project does not work,theproblemcould be a hardwareissue. -Shahrzad-

Hello! I am having the same problem (Windows 10 64bits) and Windows does not recognize the driver ... The CDC appears in Device Manager but does not recognize the driver ...

I've tried the tips (install with port driver, increase the heap) and not solved ... has no example of CDC for STM32F429-Discovery Board ....Someone has another idea?Thank you!

Microsoft changed something in Win10 that broke the (WHQL certified) driver, seen several reports now.

The example mentioned by Shahrzad can be ported to STM32F429-Discovery Board. You may use it to check the root cause of the problem you are facing. You find the example in the STM32CubeF4 under ''Application'' directory. You have just to comment the ''BSP_xxx'' commands. -Mayla-
