"printpp"是帮助用户调试的一个工具，它相当于C提供的printf函数，但它的输出设备是串口。提供的codeworrior编程范例，旨在通过给出的范例使用户对codeworrior的使用有所了解。--A debugging tool. It is equivalent to the "printf" in C, but its output device is serial port. The sample code is compiled in codewarrior. By using it, users can be more familiar with codewarrior.

此工具是arm-linux-GCC交叉编译工具（cross-3.4.4），这个是我自己编译的，下载后解压到/usr/local/arm目录下，如果你有其它版本的编译器，你最好在编译其它文件时指定这个目录，我试过，我用它编译了u-boot1.2.0没有问题，这个交叉编译器编了好长时间，我之前在网上搜了好长时间，但是没搜到，所以今天贡献出来，免得大家还得费时间去编译，我现在用是没有问题，如果有问题请多指教。希望热爱linux的同志们多贡献点好东西出来！-This tool is arm-linux-GCC cross compiler tools (cross-3.4.4), this is a translation of my own, after downloading unzip to/usr/local/arm directory, if you have other versions of the compiler, you the best in the other documents specified when compiling this directory, I tried, I use it to compile the u-boot1.2.0 no problem, the cross compiler made a good long time before I found online a long time, but did not found that the contribution to come out today, so everyone will have time to compile, I now use is no problem, please advise if there are problems. Hope love linux comrades contribution to point out good things!
