Using Arduino Uno as USB to serial converter

PPopo

Hello,

I have an STM32 Nucleo-64 board with STM32F446RE MCU.

I want to talk to it's native bootloader stored in system memory and play around with it a bit(do some in application programming, etc) via the demonstrator program.

Since the bootloader communicates via USART1/SPI1/etc I need an usb to usart/spi converter to serve as interface between my PC and the board.

I don't have a converter around atm, I do however have an arduino uno.

Would it be possible to use it simply as an USB to usart converter so I can use the demonstrator to talk to the native bootloader on the STM board's MCU? Has someone ever used an arduino in this fashion?

Thank you!
