操作一個GPIO，需要仔細對照芯片手冊，好繁瑣；每換一個主控芯片，所有工作從頭來過；想開發個現代點支持各種動效的UI，發現幾乎是不可能的事情；各種協議棧有如天書一樣，閱讀都困難，何談編寫；虛擬機技術很流行，功能很強大，想自己移植個，可是困難重重；還是放開自己吧，讓XBOOT來替你解決這些問題。 XBOOT不僅僅是一款功能強大、可移植性強、代碼復用率高的嵌入式系統bootloader，而且還是一款SOC片上系統應用軟件執行引擎，無需複雜的操作系統，APP上電直接執行。一次編寫，到處運行，不僅僅是個口號，而且還是XBOOT存在的唯一原因。一些基本特性，簡單列舉如下：

• 支持文件系統
• 支持lua虛擬機
• 支持各種協議棧
• 支持矢量圖形庫，矢量字體
• 支持各種現代GUI控件，以及動效
• 多平台支持
• 各種總線驅動，UART，I2C，SPI等等
• 各種設備驅動，GPIO，PWM，IRQ，CLK，LED，BUZZER，VIBRATOR，WATCHDOG，RNG，FRAMEBUFFER，RTC等
• 支持用lua編寫應用軟件，包含高等級API,可直接操作各種硬件抽象接口
• 應用軟件平台無關，一次編寫，到處運行

文檔及開發工具

• Xboot文檔
• 交叉工具鏈
• Eclipse集成開發環境

編譯源碼

Makefile中有兩個變量在編譯時需要傳遞，一個是交叉工具鏈，另一個是具體的硬件平台

變量	說明
CROSS_COMPILE	指定交叉工具鏈
PLATFORM	指定硬件平台，由兩部分組成， arch及mach

• Realview平台，qemu-system-arm模擬器

make clean
make CROSS_COMPILE=/path/to/arm-none-linux-gnueabihf- PLATFORM=arm32-realview

• X86_64位linux系統下的sandbox

sandbox依賴與SDL2庫，在編譯前需要安裝libsdl2-dev，以ubuntu系統為例:

sudo apt-get install libsdl2-dev

make clean
make CROSS_COMPILE= " " PLATFORM=x64-sandbox

Xboot Introduction

It very tedious that we need careful read soc datasheet when operate GPIO on soc.We always repeat working when changed the soc.its almost almost impossible to We want develop a UI that support all kinds of magic motion.Stacks of protocols are like heavenly books ,it Reading is very hard , How do we program? Virtual machine technology is very popular and it function is powerful,but it very difficult to transplant it.so we build the Xboot.it can help us deal with these problems. XBOOT is not only a powerful, portable, and highly reusable, embedded system bootloader,but also on a piece of SOC system application software execution engine, without complex operating system, electricity directly executed on the APP。 "Once written, running everywhere." It not just a slogan,but also the only reason for the existence of XBOOT. What's on the XBOOT?

• Support file systems
• Support lua virtual machine
• Support many protocol stacks
• Support graphics library, and vector font
• Supports a modern GUI, and animations
• Multi-platform support
• Bus drivers, UART, I2C, SPI and so on
• Device drivers, GPIO, PWM, IRQ, CLK, LED, BUZZER, VIBRATOR, WATCHDOG, RNG, FRAMEBUFFER, RTC, etc.
• Support application using lua, which include high-level API, can operate a variety of hardware abstract interface directly
• Application software platform has nothing to do, write once, run everywhere

Documents and Development Tools

• Xboot Documents
• Cross Toolchains
• Eclipse Integrated Development Environment

Compile The Source Code

Makefile have two variables need to pass, one is cross toolchain, the other is a specific hardware platform

variable	Description
CROSS_COMPILE	The specical cross toolchain
PLATFORM	The hardware platform, have two parts, arch and mach

• Realview Platform，qemu-system-arm Emulator

make clean
make CROSS_COMPILE=/path/to/arm-none-linux-gnueabihf- PLATFORM=arm32-realview

• Linux Sandbox On X86_64

The sandbox depends on the SDL2 library, you need to install libsdl2-dev before compile, as an example at the ubuntu system:

sudo apt-get install libsdl2-dev

make clean
make CROSS_COMPILE= " " PLATFORM=x64-sandbox
