I am working on a project for a client that involves taking the software from their cash register and loading it onto an ARM development board with very similar hardware. The company that made the software said they would only give me the binary files that are loaded into the flash memory and respectfully declined to help me any further, which was to be expected. They, at least, were able to tell me my concept is entirely possible! I was told the software consists of 3 filesystems: a ramdisk, xlib.yaffs (which runs the communications), and an app.yaffs (which loads the software). I am not sure if the flash memory chip plays any role into how the files were "compressed" but the chips are: Samsung K9F1208U0B - 64mb http://pdf1.alldatasheet.com/datasheet-pdf/view/83764/SAMSUNG/K9F1208U0B.html All 3 file systems are (ext2) Montavista Linux 3.3.1 running a 2.4.18 or 2.4.20 kernel (I don't remember and I lost my notes). I was only successfully able to mount the ramdisk. The 2 yaffs files can "mount" but all that is in the directory is a lost+found folder. Below is an init script I found in the ramdisk that has commands for loading the yaffs files: http://www.mediafire.com/view/b08ctvpe4ur8d7i/sps2000_init And here are the 2 yaffs files I am trying to mount: http://www.mediafire.com/download/mzk55b4qq0q10f9/xlib.yaffs http://www.mediafire.com/download/bvea3038y31g9s8/app.yaffs If anyone is able to help me mount them that would be awesome, (I would really love to learn how to correctly mount them) otherwise a zip file of the contents would be very much appreciated. Thank you to anyone for their help! Jason
