Hello, We've got a product where we'd like to export some storage off via USB mass storage. However to do this under Linux it has to be a standard filesystem, since the host has to under stand it, ie: FAT. Unfortunately there doesn't seem to be a reliable way of running FAT on NAND under Linux (or any way, let along reliable). One suggestion has been to make a very large file on the YAFFS partition, which is internally fat formatted, mount it loopback on our device, and export it over USB when required. Has anyone had any experience with this kind of setup? Are there any performance issues, or possibilities of corruption? The unit will probably lose power quite frequently, so we cannot be sure of a nice shutdown.
