Does not work with 1gb uSD cards
I tried to use a 1GB SD card and it was not recognized. Is there a size/type of sd cards it does not support?
I'm not aware of any unsupported SD card types. Just make sure that you got a FAT formatted partition on the SD card and that you can read/write files to the card using a computer.
I assumed it should work with all cards. But I tried it in two different carts, and it behaves the same. I also formatted it twice to be sure.
:shrug:
Did you try with other cards and does that work? If not it could be a problem with the SD card connector.
Weird. Did you have a look at the partition table to ensure that there is only one primary FAT partition? Also, what sector size is used?
Yes. There's only 1 partition. I tried formatting it as FAT and FAT32. Neither works. With FAT, it was 16k sector size.
Like I said, I formatted a 64GB card the exact same way and it works fine. And this 1GB card works in other devices.
16k sector size? FatFs that is used by KFF has these limits http://elm-chan.org/fsw/ff/doc/appnote.html#limits
Sorry.

Are these 1GB SD cards available anywhere? I think I need one to be able to find the issue
I doubt it. It's an old one I've had kicking around for a while. But it's just like this one: https://www.ebay.ca/itm/Kingston-1gb-MicroSD-card-with-Micro-SD-adapter/143732553233?hash=item217720b611:g:BPYAAOSwqK9fW~hX
If you can't find one, I could send mine to you. But then you'd probably be fixing it for nobody. :-)
These old cards are surprisingly expensive on ebay, but I managed to find a cheap Kingston 2GB card that I hoped would also fail. I formatted it with the same partition size and type as yours, but it worked fine. So I guess this is only a problem with the 1GB version.
I could mail you the one I have, but the cost might be high as well. I'm in Canada, and I suspect you're in Europe somewhere.
Yes, the shipping costs would be more than the price of a brand new SD card. Unless you really want this fixed now I'll park this issue until I can get hand on a card that fails.
