Since writing the new image will also erase the JFFS2 partition, I copied all the important config files to my computer, so I could easily restore them once the new firmware was in place. Advantages of cross-compiling. This OpenWRT image type just has one partition SquashFS vs JFFS2 20. The compression can save up 20-30% compared to JFFS2. Namely, JFFS2 uses deflate level 3 and window bits 15, while UBIFS uses deflate level 6 and window bits -11 (minus makes zlib avoid putting a header to the output data stream).

This mimics the conventional layout of CeroWRT. The official firmware's kernel lacks compiled in support for NAND flash and SquashFS or JFFS2, which would be very handy for creating a "real" (non-initrd) root filesystem with integral compression. • JFFS2 - BA T uses a python wrapper around the jffs2dump. For USB users, you wont be needing JFFS2, so DISABLE it! Another aspect to note is that some of these services (i. Data is not aligned, allowing SquashFS to pack the files tighter thus taking up significantly less space than JFFS2. 来说下Linux下的squashfs文件系统,使用squashfs文件系统作为只读分区,使用mini_fo文件将squashfs和jffs2文件系统组合成可写可读根文件系统,当写操作时会将写入内容放到jffs2文件系统中,为了深入研究squashfs文件系统工作原理,先将内核文档翻译一下。.
