Any successes with MSD? This thread seems dead

Mass storage, or what are good alternatives?

The easiest way should be to directly forward any reads/writes to an attached SD-card, so there's no need to "emulate" a filesystem.

Thanks!

So the challenge is open: Can anybody come up with a device (whatever it is) based on the mass storage class?

Sure. Here you are: http://activevb.de/members/philippburch ... dr_avr.zip
But please note: The code is quite ugly and one single construction site (Just look at the warnings generated by the compiler...), I'm not even sure what "features" are supported and working in this version. My intention was to create a USB bootloader for the bigger AVRs, but mass-storage devices only support direct reads and writes to the filesystem, so I would need to emulate a FAT... Not really suitable for a bootloader.

If you give up the project, can you please post the code somewhere (e.g. in our wiki) and add a link here in the forum? Maybe others are interested.

No, I'm sorry. And it looks like the completion goes the longer the farther away, because my time is very limited at the moment...
Maybe I discard the whole thing, some extra software shouldn't be much of a problem and would be much more reliable...

Hello Philipp Burch,
Have you already completed it ? Does it need to install extra software on the computer ?

Thanks,

Well, I'm still on it. The basic functionality seems to work quite well, the device presents itself to the host as a mass storage device. But the command flow causes some trouble, vendor-specific commands are used and although I report an error, the computer still tries the same command. But I think, I'll find ways to get it working when I've time...

Hello Philipp Burch
How is your project going on ?
"1. How are the chances for getting a low-speed mass storage device (more or less reliably) working?"

Thanks,
