He he he ;-) Yep, it boots the Linux binary I downloaded from the web site! The display driver works fine. I got a panic when it failed to find a root image. I'll have a go at getting the FireWire connection up and running in a bit. I recovered back to the original firmware without any problems, the iPod doesn't seem to have suffered from its brief brush with Linux. I suspect Apple have exposed a bi-directional serial port somewhere on that mother dock connector (or maybe that's what the extra pin on the remote connector is for?). Now that we can telnet in using IP over firewire, though, this doesn't seem to be so necessary. Out of interest, how is the second processor exposed to userspace? Is it the same as traditional SMP linux? What MMU features are missing that are required for running "normal" Linux on this hardware?
