This means we are supporting two separate file system on our embedded device, one (YAFF/JFFS) for read/write operation on flash and other (FAT) to have read/write operation on the SD/MMC card i.e multi media operations. If yes, then for the user space application is not it confusing to have two separate read/write calls api ? -- Gaur On Mon, Sep 29, 2008 at 11:33 AM, Peter Barada wrote: > On Mon, 2008-09-29 at 11:26 -0700, Yogesh Gaur wrote: > > Hello everybody, > > I am new to this group and have just start to look the yaff code and docs, > I have some of the basic doubts about the whole system on which Linux YAFF > running. > > As last week Google phone has been launched with lot of fanfare, it has > linux as it's OS, my doubt is if my phone is supporting the SD card (which > it of course does) then how the linux able to read/write to the SD card as > generally SD card have been formatted in the FAT filesystem (my assumption > in thinking that most of the users would transfer the media files from their > to the windows PC's). > > What is the interface in between the YAFF file system and the SD driver > through which file system is able to detect the SD card and do corresponding > operation of read/write? > > > None.
