Applicable for

STM32MP13x lines, STM32MP15x lines, STM32MP21x lines, STM32MP23x lines, STM32MP25x lines

This article describes the structure of the OpenSTLinux standard SDK installation directory:

SDK
├── sysroots			Root file systems
│   ├── <target>-<distro>	Target sysroot (libraries, headers, and symbols)
│   │   ├── bin
│   │   ├── boot
│   │   ├── etc
│   │   ├── home
│   │   ├── lib
│   │   ├── media
│   │   ├── mnt
│   │   ├── proc
│   │   ├── run
│   │   ├── sbin
│   │   ├── srv
│   │   ├── sys
│   │   ├── tmp
│   │   ├── usr
│   │   ├── var
│   │   └── vendor
│   └── <host machine>-<distro>_sdk-linux	Native sysroot (libraries, headers, and symbols)
│       ├── bin
│       ├── environment-setup.d
│       ├── etc
│       ├── lib
│       ├── sbin
│       ├── usr
│       └── var
├── environment-setup-<target>-<distro>-linux	Environment setup script
├── site-config-<target>-<distro>-linux		Configuration file for the target
└── version-<target>-<distro>-linux		Version file for the target

Where:

<target>	Target architecture for cross-toolchain; examples (non exhaustive list): cortexa7t2hf-neon-vfpv4 cortexa35
<distro>	Distribution; examples (non-exhaustive list): ostl
<host machine>	Host machine on which the SDK is installed; examples (non-exhaustive list): x86_64 (64-bit host machine)

The installed SDK consists of:

an environment setup script for the SDK
a configuration file for the target
a version file for the target
the root file systems (sysroots) needed to develop objects for the target system
