VCP with STM32F429I DISCO

[doddonny]

I don't understand why i can't use VCP on my STM32F429I-DISCO even if UART RX /TX pin are connected to the USB-ST-link.

I know I have to flash this ST-link V2 to V2.1 to have the VCP activated but i can't do that.

You can see on the attached schematics UART TX and RX are connected.

This is the official schematics for the STM32F429I-DISCO

Thanks for your support

You cannot do that, the STLink V2-1 uses a different mcu (STM32F103CB vs. STM32F103C8 in V2) for STLink.

Ok this is how the ST-link updater recognize compatible hardware. I didn't match the difference between 103CB and 103C8 my bad.

Thanks a lot for your fast reply !
