[help needed] UART Help

[Matty87]

Hello, trying to connect to TunerStudio using USART1 on an STM32F407VGT6.

It does not seem to work, however I am using alternate pins.

PB7 = RX1
PB6 = TX1

The firmware I am using is ' rusEFI v20230124@52586 '.

At the moment software is not smart enough to pick uart peripheral automatically. Some software developer would have to make software smarter. Hopefully it's possible without hitting DMA mapping issues.

I suggest getting some official hardware and using it as reference for any new designs.
