Release Notes Scarthgap 6.12 v2.1.0

Introduction

Astra™ is Synaptics’ new compute platform designed for the IoT market. It features a series of high-performance, AI-native, multi-modal SoCs optimized for consumer, enterprise, and industrial IoT workloads. These SoCs are equipped with hardware accelerators for edge inferencing, security, graphics, vision, and audio, and offer out-of-the-box functionality with Synaptics’ connectivity solutions.

Astra (v2.1.0) GA Release is a unified software development kit supporting the SL-Series of MPUs.

The high-level components included in this SDK are described below:

  • Upstream Linux Kernel and device tree.

  • Low-level Linux device drivers (U-BOOT) for peripheral devices.

  • Open source code for Multimedia pipelines.

  • Synaptics proprietary security approach.

  • Related SDK Documents

All of these items can be found through Synaptics’ and third parties open source Git repositories on GitHub.

Yocto SDK

The Yocto Project is an open-source collaboration project that provides templates, tools and methods for custom Linux-based systems for embedded and IoT products. By leveraging the power of the open-source development community, Synaptics hopes to provide its customers with a wider array of compatible software packages to build their products faster, with more features, while at the same time having the stability and support of a large open-source development project. Additionally, the SDK enables customers who already use a Yocto-based development environment to migrate to Synaptics class-leading silicon solutions for improved performance and additional functionality. The Yocto Project offers a vast number of software packages that provide many options.

Known Issues and Limitations

Note

Versions of U-Boot included in the Astra SDK v0.9.0 release are not compatible with Astra SDK releases v1.0 or later. Please ensure that you are using USB Tool v1.0 or later when flashing using USB. Or U-Boot v1.0.0 or later when updating with internal SPI flash. See Updating Internal SPI Flash Images using U-Boot for instructions on updating the internal SPI flash.

Note

U-Boot version v1.1.0 improves emmc flash times significantly. We recommend updating to U-Boot v1.1.0 to benefit from these improvements.

Note

SD Boot with release v1.3 and later requires updating to U-Boot v1.1.1 or later. See Updating Internal SPI Flash Images using U-Boot for instructions on updating the internal SPI flash.

Note

In Astra v1.3, the default display output for the SL1620 is set to HDMI via a DSI-to-HDMI conversion. Starting with Astra v1.4, the onboard DSI-to-HDMI converter for the SL1620 Rev D core module has been enabled. For older core modules, an external DSI-to-HDMI adapter board is required. The default display output can be switched to MIPI by following the instructions provided in the User Guides. Haier Panel Configuration Guide and Waveshare Panel Configuration Guide.

Note

In Astra v1.4, the default MIPI display on SL1680 was changed to the Waveshare 7” Panel.

Note

In Astra v1.4, ISP IOMMU only supports the NV12 format. When using RGB888 format, set the v4l2src parameters extra-controls="c,mmu_enable=0" to disable IOMMU.

Note

In Astra v1.5, the rootfs partition sizes increased to accommodate the extra packages in the OOBE images. This interferes with OTA since SWUpdate expects the rootfs partition size to be the same. To perform OTA on a system with v1.4 installed, please build an image using v1.4’s partition sizes. (See eMMC Partition Customization on Astra Machina)

Note

Network Manager can be supported in Astra 1.7, but it’s disabled by default as there are some stability issues found. If needed, Network Manager can be enabled. Please, contact the Synaptics Astra support team for more information.
