    Hello,

    I have a SanDisk 256Mb flash card which I would like to use to transfer files to the dev board. I've formatted the card as a FAT drive and can copy files to it on windows. But when I plug it into the sharp board and enter the lolo command: "mount fatfs /cf_card" it tells me that "no active partition found, trying w/o partition map"

    Is there something else I need to do? I was under the impression that sandisk cf cards were the one to use? is it too large?

    Thanks!

    I thought I had changed the file name to all caps as per the other post, but apparently I did not. I still get the error, but I can see and read the file now...

    The error you are seeing (well, what I believe you are seeing) isn't really an error at all. It just has to do with the way the Compact Flash card has been formatted.

    When LoLo tries to mount the filesystem on the card, it looks for a partition table. If it finds a partition table, it looks for the partition marked "active."

    If LoLo doesn't find a partition table, it assumes that the filesystem starts in the first block and attempts to mount the filesystem from there.

    The message that LoLo prints in this case is to let you know what assumption LoLo just made and what it is attempting to do. I do believe that this message is somewhat misleading and should be changed in future releases.

    Could you please post a copy of the "error" which you are seeing. That way I can verify that we are talking about the same thing.

    Regards,
