1. Regenerate the X-LINUX-ISP OpenSTLinux distribution

With the following procedure, you can regenerate the complete distribution to enable the X-LINUX-ISP expansion package.
This procedure is mandatory if you want to update frameworks or generate your own X-LINUX-ISP distribution by selecting the relevant ISP framework for your applications.

1.1. Download the Distribution package

• Install the OpenSTLinux Distribution package by following the steps on the STM32MPU Distribution package wiki page, but do not initialize the OpenEmbedded environment (do not source envsetup.sh).

1.2. Install the X-LINUX-ISP environment

• Clone the meta-st-x-linux-isp git repositories

Warning

The software package is provided AS IS, and by downloading it, you agree to be bound to the terms of the software license agreement (SLA0048). The detailed content licenses can be found here.

For X-LINUX-ISP v6.0.0:
 cd <Distribution Package installation directory>/layers/meta-st
 git clone https://github.com/STMicroelectronics/meta-st-x-linux-isp.git -b v6.0.0

Expand

• For a new environment

Source the build environment with the correct board and layer:

 cd ../..
 DISTRO=openstlinux-weston MACHINE=<machine> BSP_DEPENDENCY='layers/meta-st/meta-st-x-linux-isp' source layers/meta-st/scripts/envsetup.sh

Information

Possible values for DISTRO, MACHINE, and IMAGE are proposed in OpenSTLinux distribution

Expand

• For an already installed environment

Add the meta-st-x-linux-isp to the Yocto environment:

 cd ../..
 source layers/meta-st/scripts/envsetup.sh
 bitbake-layers add-layer ../layers/meta-st/meta-st-x-linux-isp/

1.3. Build the image

 bitbake st-image-isp

Information

Building the image might take a long time, depending on the host computer performances.

1.4. Program the built image

Go to the "Flashing the built image" chapter of the STM32MPU Distribution package wiki page to find out more about how to program the image.
