I looked into the folder "arch/arm/src/stm32/hardware" there does not seem to be specific definition files for STM32F427. Any idea where the definitions for the F427 family is defined. I could then move on to add support for the unsupported features of STM32F427AI.

The first thing to do is to decide which is of the supported parts is most like the STM32F427AI. Mostly likely it is just a difference in memory size or something similar. The package STM32F427AI has more pins so some other functionality must be brought out. On 2/12/2024 2:06 PM, Alan C.
