This is a note to lonesock and Rokicki..

The PM doesn't allow file attachments, so I'm attaching a file I've been testing for him and Rokicki.

Keep up the good work! SDHC is almost here!

    @ mctrivia,

    Hi! I went to your uploader site at uploader.propmodule.com. All there was was a logon screen. I logged on, which took me to the parallax forum site.

    Not sure what to do after this to upload something for a PM. Are there instructions somewhere?

    It sounds really useful, if I can figure out how to use it.

    Thanks for the help.

    @ mctrivia,

    FYI, I'm using Firefox 3.5 browser, if that makes any difference.

    Everything is done server side so browser makes no difference. It even works on my blackberry.

    mctrivia,

    Hi! It worked this time. Not sure what happened the last time.

    Thanks for the help.

    Jim

    P.S. You have a very minor typo in your user instructions on the site. The first "url" has a left bracket but no right one.

    I looked at your code, and have to say that's probably almost identical to what I would have come
    up with when merging the fsrw16 and fsrw32.

    So I guess this is the first "unofficial" release of fat16/fat32, sd/sdhc code.

    The limits of the fat32 code are as follows:

    1. No files > 2GB.
    2. It will not read past the first cluster of the root directory, nor will it extend the root directory.

    (2) is important and will be fixed. (1) I need to think about.

    Coming: seek and multiple file support.

    Thanks Tom (rokicki).

    If anyone wants to try the draft SD/SDHC code, let me know. I'll try to help.

    I've used it to load a binary file from an 8GB SDHC card, copy it to the EEPROM, and have it reboot correctly.

    From a practical perspective, it may not be a big deal, but I thought I'd mention it anyway.

    The code above does conflate the SD/SDHC and the FAT16/FAT32 distinction, so it won't work
    for FAT16 volumes on SDHC, nor for FAT32 volumes on SD. The fix is pretty straightforward.

    We should have an updated version on the fsrw source control sometime soon (perhaps even
    tonight).
