The STM32F427AI is in the same family as STM32F427xx (STM32F427V,
STM32F427Z, STM32F427I) and STM32F429xx, which are already supported.
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.

Hi Janardhan,
You can start looking at which STM32F4xx chip existent on NuttX is more
similar to STM32F427AI and start your port based on it.
You can do it using the chip datasheet and/or reference manual, writing
down the difference in peripherals, registers, etc.
Normally STM32 devices share many features, but sometimes they have small
incompatibilities.
So, look the existing chips on NuttX (nuttx/arch/arm/src/stm32/hardware/
and nuttx/arch/arm/include/stm32/
Best Regards,

Hi Community,
I have a board which uses STM32F427AI, and was planning on running a
middleware which runs over nuttx, but only noticed, after the board arrived
from manufacturing that there is no option to select, STM32F427AI from the
menuconfig/qconfig.
I don't have an option to replace the chip to the ones which are currently
supported and thus, want to add the support for STM32F427AI, but don't
know where to start.
Hoping to get some direction, from where I can start.
Thanks in advance.
