Recently, RISC-V SIG has successfully implemented the adaptation of the Euler operating system on the LicheePi 4A development board. Currently, the latest version of the openEuler RISC-V 23.03 V1 image is available on the LicheePi 4A development board, which once again demonstrates the new breakthroughs made by openEuler in promoting the development of the RISC-V ecosystem.

openEuler adapted to the LicheePi 4A development board is open to the community
The early test image of openEuler RISC-V for the LicheePi 4A development board has been launched and can be downloaded for trial use. The test image is based on the latest 23.03 innovative version, using the firmware and kernel branch that the manufacturer has open sourced. Tested by RISC-V SIG, the basic system, wired network, WiFi and several other peripherals are now available, which can support the basic functions of the basic system and XFCE desktop, and the overall operation is relatively smooth.
Of course, there are also some known problems with the current image. First of all, GPU support is yet to be improved, currently only supports LLVMpipe mode. Thanks to the performance advantages of TH1520, the glxgears test on this platform can reach 200+ fps, and the HDMI output and system graphical interface are basically smooth. Secondly, it only supports booting from eMMC for the time being, and needs to be programmed through fastboot. The initial 8+8 configuration can meet basic needs, but there are still storage limitations. The follow-up openEuler RISC-V will improve the relevant basic support, and will provide further support for microSD card booting and some peripherals. The official image 22.03 LTS and 23.03 with more functional support will be released and updated.
LicheePi 4A: Multi-core heterogeneous high-performance RISC-V SoC
It is reported that LicheePi 4A is the first RISC-V development board whose performance is comparable to that of Raspberry Pi 4. It is based on Alibaba Pingtouge TH1520 chip, equipped with 4-core 2.0GHz C910 core, 4TOPS NPU and 50GFLOPS GPU, providing developers with powerful performance , to meet the needs of various application scenarios.
The development board supports a rich set of peripherals, including Gigabit Ethernet port (supports PoE), USB 3.0 Type A port, HDMI 2.0, 3.5mm audio interface, microSD card reader, and 5V DC power input. Additionally, the development board integrates WiFi and Bluetooth adapters, as well as MIPI-DSI and MIPI-CSI connectors for the display and camera. These rich hardware features make LicheePi 4A a powerful and flexible development platform to meet the needs of developers in various fields.

Promote the implementation of a wide range of application scenarios for RISC-V high-performance applications
RISC-V SIG will take advantage of the computing power of RISC-V vector extension instructions (RVV 0.7), build an entire operating system using a toolchain that supports RVV 0.7, perform full-system compilation, and discover more performance potential. To achieve this goal, we will cooperate with the RuyiSDK team of the Institute of Software, Chinese Academy of Sciences to fully tap the potential of the RISC-V field, and at the same time provide "RuyiSDK" support for more RISC-V developers.
At present, the adaptation work of LicheePi 4A is in full swing, and we will continue to develop more new functions and transplant the latest openEuler RISC-V version image. However, the openEuler RISC-V operating system based on LicheePi 4A still has room for optimization in terms of GPU adaptation and user experience. We sincerely invite interested friends and test volunteers to join and download the development version image to jointly explore and solve possible problems. Problems, promote the prosperity and development of RISC-V development ecology!
