pcDuino的linux移植一
最近pcduino官方公布了kernel源码，很是兴奋，决定开始在pcduino上移植linux系统，有兴趣的一起讨论哈目标：1.移植u-boot 2012.102.移植linux内核3.移植最小文件系统开发环境：系统：ubuntu 10.04.4单板：pcDuino编译器：arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2下面移植pcDuino官方最新公布的u-boot1.获取源码pcDuino提供的u-boot-sunxi https://github.com/pcduino/kernel 下载u-boot-sunxi源码获取交叉编译链 http://code.google.com/p/smp-on-qemu/downloads/list 选择arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2并下载。然后在ubuntu下直接解压即可，还要配置环境变量sudo gedit/etc/environment修改PATH,在最后再加“:/.../arm-2009q3/bin”,其中“...”是上面arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2解压的路径。接着Log Out ubuntu系统，就可以直接使用交叉编译链。2.编译u-boot解压上面下载的u-boot-sunxi-sunxi.zip到工作目录，接着配置单板并编译make pcduino CROSS_COMPILE=arm-none-linux-gnueabi-最后输出如下，编译成功arm-none-linux-gnueabi-ld-g -Ttext 0x50000000 \-o hello_world -e hello_world hello_world.o libstubs.o \

取下tf卡，插到pcDuino的tf卡槽，接上串口线，pcDuino默认是从sd卡启动的，上电串口输出如下：U-Boot SPL 2012.10 (Apr 19 2013 - 18:46:44)
DRAM: 1024MB
SUNXI SD/MMC: 0
U-Boot 2012.10 (Apr 19 2013 - 18:46:44) Allwinner TechnologyCPU: SUNXI Family

sun4i#u-boot基本移植成功，下阶段实现目标二linux内核移植。
