The first Source of the Dragon Core Club is based on the Open source, the owner of the Dragon Core 1C processor - Zhilong V2 edition has passed the crowded goods. Compared with the first versions, it has great improvements based on the user's feedback, supports the latest version of the RT-Thread real-time operating system, and the first time the U-Boot is added to implement the system boot, and it is more convenient for engineers to develop. There has been a Wi-Fi remote control car work with Chicillin V2 motherboard.
According to reports, Zhilong is the first open source hardware and a masterboard based on the domestic autonomous dragon core CPU, with the following features:
The interface is rich: more serial data and serial sensor communication needs can be met in the Internet of Things applications, and the integrated network port can enable multiple serial port devices to access the Internet. Moreover, the price of Dragon core 1C chip is inexpensive, cost-effective, suitable for scale promotion.
The motherboard can be completely hand-welded. It is convenient for DIY: Longxin 1C chip adopts QFP package. The chip tube foot is suitable for electronic engineers to be self-welded, and "Open source dragon core" only needs a skilled welder, and it can be welded to all components one night. Suitable for personal goods small teams for multiple iterative development.
Fully open source: Zhilong motherboard is designed from hardware PCB to Bootloader to open source, and there is no restrictions on users, free use, modification, and then release.
The manufacturer supports large and chip customizable: From the long run, the dragon core chip is an autonomous CPU kernel. Its custom chip design is strong, the license fee is low, and it is very good to choose from design to product costs.

It is also known that the latest version of the RT-THREAD real-time operating system has been successfully transplanted in Zhilong V2 motherboard, newly adding multi-channel serial port support.
RT-Thread is an open source embedded real-time operating system from China. It is developed from domestic professional developers since 2006, in addition to the real-time operating system kernel similar to Frertos and UCOS, including a series of application components and drivers. Framework, such as TCP / IP protocol stack, virtual file system, POSIX interface, graphical user interface, USB protocol stack, dynamic module, etc. The industry and equipment have been verified as a highly reliable real-time operating system.
RT-THREAD Real-Time Operating System Follow the GPLV2 + license, real-time operating system kernel and all open source components can be used free of charge in commercial products without any potential business risks.
The latest version of RT-THREAD has been ported to Open source Longxin Chuangke Motherboard Zhilong V2
RT-Thread has supported the dragon core 1b and 1c processor, and the dragon core club is based on open source dragon core Children's motherboard - Zhilong, further in-depth cooperation, the hardware drive, kernel optimization, function expansion of dragon core, etc., development dragon core processor Special security, hard real-time operating system version on the platform.
This is also an important new feature of this Zhilong V2 version to increase support for common boot loader u-boot. Boot Loader is a bootstrap running before operating the operating system kernel. The mainstream Boot Loader in the embedded industry is U-boot, supporting a variety of platforms.

The P1601-DK02 development board is a desktop full-featured programmable computer based on the PARALLLA-16 board with full computer profile.
The Longxin motherboard is commonly commonly used, although PMon is a powerful program of the BIOS and BOOT Loader sections, it has always been the standard configuration of the dragon core motherboard, but it also leads to the unfamiliar development of the Boot loader on the dragon core motherboard. . Now Longqin Chuangke's motherboard has added support for U-boot, which is convenient for developers. Thank you for the contribution of Dragon Cove developers Tang Haifeng, and also welcome more developers to improve U-boot on the dragon.
U-boot successfully started on the open source dragon core
It is reported that Zhilong motherboard V2 version has been delivered through the network crowdfunding, and there is still a small amount of spot to sell online or Taobao sales, open source dragon core motherboard - Zhilong's reservation website www.loongsonclub.com/gw/ Taobao shop Loongsonclub .taobao.com / Contact email
