• Support ST 2A algorithms offering improved accuracy and stability
• New lux estimation service

Limitation

• None

Overview

X-LINUX-ISP is a free of charge open-source software package targeting the STM32MP25x and STM32MP21x series that embed an ISP camera pipeline.
This meta-layer delivers the STM32 ISP IQTune application running on the target to interact with the STM32 ISP IQTune desktop application executed on the host computer (connected through USB), allowing access to the ISP configuration and sensor tuning procedure.

meta-st-x-linux-isp

X-LINUX-ISP OpenEmbedded meta layer to be integrated into OpenSTLinux distribution. It contains recipes for STM32 ISP IQTune embedded application and its dependencies for STM32MP25x and STM32MP21x series.

Compatibility

The X-LINUX-ISP OpenSTLinux Expansion Package v6.2.0 is compatible with the Yocto Project™ build system Scarthgap. It is validated over the OpenSTLinux Distribution v6.2.1 on STM32MP25x and STM32MP21x series.

Versioning

The major versioning of the X-LINUX-ISP OpenSTLinux Expansion Package is aligned on the major versioning of the OpenSTLinux Distribution. This prevents painful backward compatibility attempts and makes dependencies straightforward.
The X-LINUX-ISP generic versioning vx.y.z is built as follows:

• x: major version matching the OpenSTLinux Distribution major version. Each new major version is incompatible with previous OpenSTLinux Distribution versions.
• y: minor version, which is changed when new functionalities are added to the X-LINUX-ISP OpenSTLinux Expansion Package in a backward compatible manner.
• z: patch version to introduce bug fixes. A patch version is implemented in a backward compatible manner.

Available frameworks and tools within the meta-layer

X-LINUX-ISP v6.2.0 expansion package:

• ISP software:

  • ISP software framework is now part of OpenSTLinux 6.2.1 distribution (not delivered within x-linux-isp expansion package)

• Utilities:

  • STM32 ISP IQTune application (running on the target) used to tune the ISP by providing communication services between the host and the device

• Host tools:

  • STM32 ISP IQTune desktop application that provide services to tune the ISP present in STM32 devices
