STM32F429-DISC1 USB CDC (VCP) is not detected by windows PC.

[MParm]

Hello Community,

I have developed an application on STM32F4-DISC0 Board and it is working fine. Now I ordered a new version of the board which is STM32F429-DISC1.

Surprisingly, same code which is working just fine on DISC0 is not working on DISC1.

The main problem I am noticing is USB VCP is not being detected by windows PC.

Can anyone suggest me any solution for the same??

Thanks in Advance !!!!

USB VCP is only available on DISC1. So your "main problem" is not clear. But perhaps DISC1 pulls TX high while DISC0 keeps that line floating. So perhaps this keeps your program hanging.

Thanks Uwe,

Yes I'm aware of the fact that "USB VCP is only available on DISC1".

In my code, I have used "micro usb connector (CN6)" in USB CDC mode on DISC0 and it worked fine.

Now, the same code is not working on DISC1, Don't know the exact reason but I suppose it is because of "USB VCP is only available on DISC1".

Thanks,
