太空鏈05.01-05.07工作總結
太空區塊鏈節點
Blockchain node in space
太空區塊鏈節點首批測試板已於上周正式交付。
後續硬體交付驗收
硬體團隊將繼續對測試板進行後續的電學測試驗收工作，以保證及時發現投產、電裝工藝、硬體選型及設計錯誤造成的隱藏問題，並在正樣中進行修復。
軟體介面測試驗收
在硬體團隊進行後續測試工作的同時，軟體團隊也並行開始對測試板的外設介面進行測試。其中測試板的介面包括1路I2C、2路CAN介面、1路RS422數據介面、2路UART介面、1路USB介面以及1路千兆網介面、GPIO介面以及Xilinx JTAG調試介面。

開源軟體系統
SpaceChain OS
本周，經過歷時一個月的測試和修改，OS團隊完成虛擬機的全部開發過程，實現了虛擬機的設計功能，現在已運行正常。團隊已經將源代碼上線開源，並輔以虛擬機使用說明文件，社區可訪問SpaceChain OS Github獲取虛擬機文件，然後把解壓後文件載入到Simulator中即可使用。解壓後文件在2GB以上，請預留足夠空間。
虛擬機詳細使用方法，請參考之前的周報和GitHub中文檔：虛擬機使用手冊所述內容。
開源文檔整理工作：
團隊持續開展開源軟體文檔編輯與上線工作，本周團隊在Github上新增以下文檔：
SP002011 虛擬機使用手冊 CN——本文檔介紹了虛擬機的使用場景和基本使用方法。涉及到Qtum命令和使用方法，請參考其他手冊和Qtum相關文檔。
SP002005 SpaceChainOS 簡介 CN——本文檔介紹了SpaceChainOS功能，指標，使用場景，配套的工具。英文版正在翻譯，將儘快發布。
更新後的文檔體系如下：

經過團隊內部方案評審，最終評審通過了之前制定的初步方案。開發板採用TI公司Sitara? AM335x 處理器，處理器主頻為800Mhz。可以支持絕大多數應用的需求。開發板結構如下：
之後，我們會按照方案設計原理圖和PCB，並儘快投產，以期儘早向社區提供可運行區塊鏈應用的嵌入式設備。
SPC Weekly Report (May 1 – May 7, 2018)
This week, we focus more on the progress of the hardware and software technology.
TECHNOLOGY PROGRESS:
Blockchain node in space
The first batch of test boards for space blockchain nodes was delivered last week.
Follow-up hardware delivery acceptance
The hardware team continues to conduct subsequent electrical tests and acceptance work on the test board to ensure that the hidden problems caused by the production, electrical installation process, hardware selection and design errors are detected in a timely manner and repairs are made in the same way.
Software interface test acceptance
While the hardware team is performing follow-up testing, the software team has also started testing the peripheral interfaces of the test board in parallel. The interface of the test board includes one I2C, two CAN interfaces, one RS422 data interface, two UART interfaces, one USB interface, one Gigabit Ethernet interface, GPIO interface and Xilinx JTAG debug interface.

SpaceChain OS
After a month of testing and modification, the OS team completed the entire development process of the virtual machine and realized the design function of the virtual machine. Now the system is running normally. The team has opened the source code to the public, supplemented with the virtual machine usage documentation. The community can access the SpaceChain OSGitHubto obtain the virtual machine file, and then load the extracted file into the Simulator and use it. Decompress the file after 2GB. Do reserve enough space.
For detailed usage of the virtual machine, refer to the previous weekly report and the GitHub documentation: Virtual Machine User"s Manual.
open source document finishing work
The team continues to carry out editing of the open-source software document and online work. This week, the team added the following documents on GitHub:
1. SP002011 Virtual Machine User Guide CN — This document describes the usage scenarios and basic usage of the virtual machine. Refer to other manuals and Qtum related documentation for Qtum commands and usage.
2. SP002005 Introduction to SpaceChain OS CN — This document describes SpaceChain OS features, indicators, usage scenarios and supporting tools. The English version is still being translated.
The updated document system is as follows:
Open Space Hardware System
SpaceChain Hardware
After the teams internal program review, the final review passed the initial program developed. The development board uses TI"s SitaraTM AM335x processor with a processor clocked at 800Mhz. It can support the needs of most applications. The development board structure is as follows:
We will design schematics and PCBs according to the plan and start production as soon as possible so as to provide the community with embedded devices that can run blockchain applications.
