Hi, Let me show something "magic" :
$ cd nuttx/arch/arm/src/stm32/hardware/ $ git grep STM32F427 Now you have super power!!! ;-) Best Regards, Alan On Wed, Feb 14, 2024 at 2:25 AM Janardhan Silwal < janardhansil...@outlook.com> wrote: > I looked into the folder "arch/arm/src/stm32/hardware" there does not seem > to be specific definition files for STM32F427.
