这个程序是我自己写的，主要用于PXA255的烧写，经过我修改后，特别方便JTAG下，CPU的调试，可以测试CPU的各个IO脚，无需跑操作系统，即可简单查看外设是否正常。参照APP子目录下的使用方法即可。在微软的JflashMM上做了修改。-I wrote it myself, mainly for the PXA255 burning, I have revised, especially convenient JTAG, the CPU test, the CPU can test various IO feet without running the operating system, simple View peripherals can be normal. APP subdirectory under the light of the method can be used. Microsoft has done a JflashMM changes.
