Install the SDK

1. Overview

This stage explains how to install the SDK.
The SDK for OpenSTLinux distribution provides a stand-alone cross-development toolchain and libraries tailored to the contents of the specific image flashed in the board.

2. Host computer configuration

2.1. Install extra package

In order to do basic development tasks or basic cross-compilation, some extra Ubuntu packages should be installed:

 sudo apt-get update
 sudo apt-get install sed wget curl cvs subversion git-core coreutils unzip texi2html texinfo docbook-utils gawk python-pysqlite2 diffstat help2man make gcc build-essential g++ desktop-file-utils chrpath libxml2-utils xmlto docbook bsdmainutils iputils-ping cpio python-wand python-pycryptopp python-crypto
 sudo apt-get install libsdl1.2-dev xterm corkscrew nfs-common nfs-kernel-server device-tree-compiler mercurial u-boot-tools libarchive-zip-perl
 sudo apt-get install ncurses-dev bc linux-headers-generic gcc-multilib libncurses5-dev libncursesw5-dev lrzsz dos2unix lib32ncurses5 repo libssl-dev
 sudo apt-get install default-jre

2.2. Additionnal configurations

• Allow up to 16 partitions per mmc

By default, on Linux system, a maximum of 8 partitions are allowed on mmc. All Packages (Starter Package, ...) need more than 10 partitons for the storage device. In order to extend the number of partitions per device to 16, the following options must be added to modprobe:

 echo 'options mmc_block perdev_minors=16' > /tmp/mmc_block.conf
 sudo mv /tmp/mmc_block.conf /etc/modprobe.d/mmc_block.conf

3. Download the SDK

The software package is provided AS IS, and by downloading it, you agree to be bound to the terms of the software license agreement (SLA). The detailed content licenses can be found here.

Warning

To download a package, it is recommended to be logged in to your "myst" account [1]. If, trying to download, you encounter a “403 error”, you could try to empty your browser cache to workaround the problem. We are working on the resolution of this problem. We apologize for this inconvenience

5. Starting up the SDK

Information

The SDK environment setup script must be run once in each new working terminal in which you cross-compile

For ecosystem release v1.2.0

 cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v1.2.0/Developer-Package 
 source SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

For ecosystem release v1.1.0

 cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v1.1.0/Developer-Package 
 source SDK/environment-setup-cortexa7t2hf-neon-vfpv4-openstlinux_weston-linux-gnueabi

For ecosystem release v1.0.0

  cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v1.0.0/Developer-Package 
 source SDK/environment-setup-cortexa7t2hf-neon-vfpv4-openstlinux_weston-linux-gnueabi

The following checkings allow to ensure that the environment is correctly setup:

• Check the target architecture

 echo $ARCH
arm

• Check the toolchain binary prefix for the target tools

 echo $CROSS_COMPILE
arm-ostl-linux-gnueabi- /* For ecosystem release v1.2.0  */

arm-openstlinux_weston-linux-gnueabi- /* For ecosystem release ≤  v1.1.0  */

• Check the C compiler version

 $CC --version
arm-ostl-linux-gnueabi-gcc (GCC) 8.2.0 /* For ecosystem release v1.2.0  */

arm-openstlinux_weston-linux-gnueabi-gcc (GCC) 8.2.0 /* For ecosystem release ≤  v1.1.0  */

• Check that the SDK version is the expected one

 echo $OECORE_SDK_VERSION
  
2.6-openstlinux-20-02-19 /* For ecosystem release v1.2.0  */

2.6-openstlinux-4.19-thud-mp1-19-10-09 /* For ecosystem release v1.1.0  */

2.6-openstlinux-4.19-thud-mp1-19-02-20 /* For ecosystem release v1.0.0  */

If any of these commands fails or does not return the expected result, please try to reinstall the SDK.
