I am looking to see if this product can boot off a USB Stick with Debian?

A qualified yes. It must boot off an SD card with the GPU firmware and a bootloader or linux kernel on it, but once that's done, it can chain boot off any device the initial bootloader/kernel has drivers for. That includes USB sticks (and USB HD, network, ...)

Not that hard to use an old 16 or 32MB SDCard for the bootloader. :p

Sounds like you're getting the right ones! I was referencing the fact that SD cards are readily available, not necessarily the size itself ;)

Is there any way to change the GPU firmware in order to boot a USB Stick directly?
I can use a SDcard for the first boot, but if i need it every boot would be very sad.

So can you put Puppy (or similar) on the SD and direct boot from it?

I believe that should be possible - this just a replacement of the debian (or whatever)  compressed file with the puppy one on the root of the SD card.

You can put the "boot" stuff (GPU boot file etc.) only on the SD card, but then redirect it to actually boot the rest of the system from a USB device.

We've moved the file system onto a portable HD to give us more storage, and I'm guessing if you can boot from USB HD, you'll be able to boot from a USB stick.

We will be doing a WIKI post about it (if it hasn't already been done).  Didn't take long to do.

Excellent. I will let the Sugar on a Stick people know. This is the Fedora Linux remix of the Sugar education software for One Laptop Per Child on a bootable USB drive. An ARM version is in the works.

Hmmm... Could you boot an ARM compiled boot launcher and then boot a regular version of an OS?

Linux is a regular OS. I'm not sure if you mean MacOS / Windows or if you mean a non-ARM Linux. It doesn't matter; the answer is no.

You need an ARM compiled operating system, because the central processor (the "chip" if you like) is an ARM, whereas the processor in your desktop machine is probably an Intel x86. The two of them understand totally different languages.

The fact the RaspPi boots from an SD card is irrelevant.
