Options? Need to read off flash card, parse, and send out SPI - What am I up against?

[skimask]

I need to get chunks of data off some kind of flash RAM - SD, MMC whatever, that will have been saved in a FAT file system in simple file names or numbers. I have no need to read the names of the files - in fact, I may even be able to refer to them by their starting and ending blocks, or to grab individual parts of one big file - example:

DOSonChip - plug in an SD card, fire off some serial commands, and you're set.

Other than that, grab a few datasheets around the 'net and access to an SD card or an Atmel Dataflash chip is a relative piece of cake with PBP.

Hello,

Thanks for the feedback. I looked at the DOSonChip, and it's a great product, no doubt, but way more powerful than I need for this application, plus expensive - at least in production quantities.

I'll keep digging. If I come up with something good, I'll post it.

Anybody used these VLSI MP3 decoder chips with any success?
