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!
