具体移植进程见linux移植一、二、三。花了不少间时啊，这是移植心得。
pcduino linux移植期间遇到了不少问题，结总如下：
1.pkg-config可以决解明显在自己器机上编译好好的，在别人电脑上编译就不行问题,它能为已安装的库时供提一统接口。解了pkg-config决解Package libusb-1.0 was not found in the pkg-config search path
2.用busybox制造文件统系时，要注意文件的性属。括包态动接链、执行权限等。通过sudo cp -pR file1 file2,留保文件性属，否则统系跑步起来。
3.ubuntu下烧写tf卡命令，这里易容出问题，发明杂牌子的tf卡就不行，一卡了一段间时，最后断果Kingstorm
4.Kernel panic - not syncing: No init found. Try passing init= option to kernel,这个问题说了找不到init，而我置设init=/sbin/init，显然没问题。原因安在呢？
change@change:~/Si/A10/pcduino/rootfs$ ls sbin/ -l
lrwxrwxrwx 1 change change 14 2013-04-28 21:16 init -> ../bin/busybox
change@change:~/Si/A10/pcduino/rootfs$ file linuxrc
linuxrc: symbolic link to `bin/busybox'
发明bin/busybox是一个态动接链库文件，赖依交叉编译链的响应库。而交叉编译链库有很多，试了发明../arm-2009q3/arm-none-linux-gnueabi/libc/armv4t/lib/和 /home/change/tools/arm-2009q3/arm-none-linux-gnueabi/libc/armv4t/usr/lib/ 下的*.so*库可以应用。
