Is there a way to use uart on stm32f103c8t6 for VCP over debugging chip or is there

a flash limitation for debugger firmware ? For Nucleo411 there is VCP support via STM32F103CBT6 which has twice as much flash as the debug chip on the f3discovery.

Any Ideas ?

Kind Regards Jean

Most DISCO boards don't support the VCP functionality.

The new STM32F469I-DISCO also has an STM32F103CBT6 and supports both the mbed and VCP functionality.

Dear clive1,

Thank you for the fast response.

is it possible to flash the Stm32f3discovery debugger with the STM32F469I-DISCO debugger image ?

I've tried to burn f2_4.bin from 411nucleo into the STM32F3Discovery board. After burning f2_4.bin Windows started to install the VCP driver but afterwards debugging was not possible. So i burned f2_1.bin and my debugger was alive again. I guess it's faster to use another open source alternative.
