FAT32 bootstrap proof of concept. Read fixed name file out serial port in just over 2K with the libc housekeeping.

(I’m working on a ex-nihilo FAT32 + SDHC card filesystem there, other posts might be of interest – TZ)
microSD to full sized adapter:

If the card is compatible (3.3v, has the SD commands, etc.), it will work. Including things like the EyeFi. Note they might pull more power.
I don’t know if the EyeFi can be formatted and work with FAT16, and it only uploads certain picture formats like JPEG (except the Pro), but as long as the file is large enough, and is a valid JPEG, it will upload it. However a valid JPEG can be a single pixel with just under 64K per text comment block. I haven’t yet tried writing them slowly to see if it would do nothing, write a partial, or wait until the end-of-jpeg and send it.
Experimental FAT32/SDHC firmware: http://github.com/tz1/sparkfun – hyperlog is targeted at OpenLog hardware, fat32cli is a command line version that is NOT compatible with the current openLog commands but does similar things. Also a version for the jpeg trigger
