STM32 ARM Linux Overview
|
||||
========================
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
The STMicroelectronics STM32 family of Cortex-A microprocessors (MPUs) and
|
||||
Cortex-M microcontrollers (MCUs) are supported by the 'STM32' platform of
|
||||
ARM Linux.
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
|
||||
For MCUs, use the provided default configuration:
|
||||
make stm32_defconfig
|
||||
For MPUs, use multi_v7 configuration:
|
||||
make multi_v7_defconfig
|
||||
|
||||
Layout
|
||||
------
|
||||
|
||||
All the files for multiple machine families are located in the platform code
|
||||
contained in arch/arm/mach-stm32
|
||||
|
||||
There is a generic board board-dt.c in the mach folder which support
|
||||
Flattened Device Tree, which means, it works with any compatible board with
|
||||
Device Trees.

The STMicroelectronics family of Cortex-M based MCUs are supported by the
|
||||
'STM32' platform of ARM Linux. Currently only the STM32F429 (Cortex-M4)
|
||||
and STM32F746 (Cortex-M7) are supported.
|
||||
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
|
||||
A generic configuration is provided for STM32 family, and can be used as the
|
||||
default by
|
||||
make stm32_defconfig
|
||||
|
||||
Layout
