Give this a try

Thanks, that link works.

BTW do you know if Jeremy has any plans to get sub-directories working?

[mackrackit]

I will ask him.

Hello Guys,
i am new with sd cards and i have read almost all posts about them and seriously only you are talking about FAT32 format and have the files.Can anyone guide me?? I am not asking to get free code or something im just stuck here . I have tried just to initialize the card but i failed. Iam using 18F26K22 hardware SSP1 module for communicating with the card and hardware EUART to debug the programm. I dont want to use the SD_WE and SD_CD and i simply didn't connect them.

Here is what i tried so far but the programm is stucked at "Gosub FSinit" command.

and my SDFSHC32D.bas file is attached.

Im looking forward for an answer, Kostas.

I'm having the same problem described at the end of this (dead?) thread. Was there ever a solution? BTW, I had it working for FAT16 - so hardware is probably OK.

Thx

FAT16 works. For 32 there is nothing good up to this moment. Also other compilers are good only at 16 as far as I know.

But what about the posts above. Looks like some folks had a FAT32 library working. Am I missing something?
