How to start with custom Arduino STM32 board

Other Hardware 3rd Party Boards

I have installed STM32 boards into the IDE. Now, how can I tell the IDE for instance what UART or SPI pins my board uses.
I have several STM32 boards, like STM32F746 and STM32H750, and using Arduino libraries is much easier that doing my own.

If your boards are presents in "boards" menu of arduino IDE - you dont need any additional tuning of pins etc. if that is not your case - you need to add your boards to IDE, but it is not so easy.
In addition to describing the pins and indicating the presence of various peripherals - the number of UARTs, SPI I2c etc., you will also need the correct file for the linker, indicating the sizes and boundaries of various memory areas

I see. I have configured peripherals my own way.
