重点介绍了SQUASHFS文件系统,其编译,制作,挂载和内核修改坏块处理.因为yaffs2文件系统内核支持比较成熟,其本上只需编译即可,后面也介绍了目前较常见的几种文件系统. 关键字: squashfs linux flash 坏块处理-Highlighted SQUASHFS file system, the compilation, production, mounting and handling bad block kernel modifications. Yaffs2 file

这些源码是从lzma sdk c代码部分抽选出来的，可以很好的移植到需要压缩，解压的嵌入式项目中。具有很好的实用性。-These source is from the the lzma sdk c code part of the lottery, good ported to need compression, decompression project. Has a good practicability.

在ARM926EJS的内核上，配很小的SPI flash就可以烧录u-boot, 采用lzma的压缩方式，来压缩u-boot,代码包括实现内存分配，解码函数等重要的函数，效果非常不错 -On ARM926EJS kernel, with a small SPI flash can burn u-boot, using lzma compression method to compress u-boot, including the realization of the important fun
