Recently, the HH-SCDAYU200 development kit produced by Runhe Software is based on the Rockchip RK3568 chip. The code has entered the backbone of OpenAtom OpenHarmony (hereinafter referred to as "OpenHarmony"), and supports OpenHarmony 3.1 Release version for the first time, realizing the "rich device platform" The breakthrough from 0 to 1 marks the official launch of OpenHarmony's industrial applications in the field of rich devices.
OpenHarmony 3.1 Release is a new version released by the Open Atom Open Source Foundation on March 31, 2022, with rich system functions and features. As a high-performance chip, RK3568 has multi-core capabilities, GPU capabilities, and multimedia capabilities that can better leverage the capabilities and features of OpenHarmony 3.1 Release.
OpenHarmony will continue to polish the HH-SCDAYU200, optimizing from the bottom to enhance user experience. At the same time, OpenHarmony will implement rich application samples based on HH-SCDAYU200, such as distributed music player, distributed mail, distributed tablet, distributed games and other applications, enriching the OpenHarmony application ecology.
HH-SCDAYU200 unboxing experience
The HH-SCDAYU200 development kit has a beautiful appearance and rich interfaces.
After starting up, you can see that the desktop of the system is clean, and all kinds of system applications are complete.
In the settings, you can see that the system version number of HH-SCDAYU200 is OpenHarmony 3.1 Release.
In addition to common system applications, HH-SCDAYU200 also supports various third-party applications, such as distributed applications, multimedia applications, game applications, etc.

RK3568 chip
The RK3568 chip is a mid-to-high-end general-purpose SoC. It adopts a 22nm process technology and integrates a 4-core ARM Cortex-A55 processor with low power consumption and high performance. It is specially designed for AIoT devices and provides multiple powerful embedded hardware engines to Optimize application performance.
(RK3568 chip functional framework)
RK3568 H.264 decoder supports 4K@30fps, H.265 decoder supports 4K@60fps, H.264/H.265 encoder supports 1080p@60fps, and efficient JPEG codec; embedded 3D GPU is compatible with OpenGL ES 1.1 /2.0/3.2, OpenCL 2.0 and Vulkan 1.1, the special 2D hardware engine maximizes the display performance and provides a very smooth operating experience.
In addition, RK3568 has a high-performance external memory interface to ensure high-capacity and high-stable operating memory bandwidth of the system, and supports DDR3, DDR3L, LPDDR3, DDR4, LPDDR4, LPDDR4X and other memory models. When the OpenHarmony 3.1 Release was released, RK3568 was successfully integrated into the OpenHarmony backbone, and became the first officially released development board and version function test platform of the backbone version.
HH-SCDAYU200 parameters and characteristics

Development Board Introduction
(Development version introduction)
Interface Reuse Description
BT1120 : Use GMAC1 related pins for BT1120, then BT1120 related output can be realized (currently there is no BT1120 interface left on the bottom board).
PCIE : Currently there is 1x 2Lanes PCIe3.0 Connector (RC Mode), if you want to add PCIE2.0, configure MULTI_PHY2 as PCIE mode.
SATA : Currently there is 1x SATA3.0, and 3x SATA3.0 can be realized by configuring MULTI_PHY0 and MULTI_PHY1 as SATA.
RGMII : Currently there are 2x RGMII, if you want to add QSGMII, you need to configure MULTI_PHY1, MULTI_PHY2 as QSGMII.
(HH-SCDAYU200 chassis specifications)
After HH-SCDAYU200 is integrated into the backbone, it will be the default support platform of the official standard system of OpenHarmony and will receive long-term and stable support. The new features of OpenHarmony will be adapted on this platform first, so that developers can experience the features of the latest version of OpenHarmony through HH-SCDAYU200 at the first time.
Specifically, HH-SCDAYU200 will improve the following capabilities in the future: long-term support based on Linux 5.10 kernel feature; support for HDMI, LVDS, EDP and other interfaces LCM; support for NPU; support for Modem capabilities; support for TEEOS . Stay tuned.
