Do you have a link to the actual page? Or search terms I can use? The problem with wikis (IMHO, and not just the RockBox wiki...) is that they're such a pain in the a$$ to navigate. You can only get to a page by searching for it. God only know how many "hidden" pages are on the average wiki, just because there are no external links...

For a music player, or even a full-fledged PDA, this is waaay overkill. I was thinking an ARM-9, prolly running at about 200MHz.

The problem with users is that they can't be bother to look for themselves. The iriver port is linked on the front page of Rockbox.com as well as the wiki.

Next time look before asking.

FWIW the Ipod is a dual core ARM7 running at

I think 200MHz ARM9 CPU is fine if it's not much more expensive than a slower CPU. You can change the clock to save battery time (like we do on most targets). The Toshiba Gigabeat we are working on has a 300MHz ARM9.

You just need a DAC and a (color) display for that.

Hard-drive or Flash-based really only depends on what you want. Flash is more robust but with a hdd you can put a lot more music on it.
For a flash-based player I don't think you need that much RAM, as reading from flash doesn't cost you much battery time compared to a hard-drive.
If you go with the hard-drive then you want a lot of memory (at least 32MB I would say) so many songs can be played from RAM before the disk needs to spin up again.
It might speed up the port if you use parts already supported by other players:

It's not completely up-to-date. I'll add some more Gigabeat parts to the list later.

Ouch. Well, first, rockbox.com is a GoDaddy parked domain. You must mean rockbox.org.
On the rockbox.org front page there are no links to any iRiver port (unless you mean the "Daily Builds" page?).
And I'm not looking for a port. I'm looking for hardware specs and suggestions (though Rockbox is maybe the wrong place to be looking, but I figured if you're writing iPod firmware, you must know the iPod hardware pretty well, right?). But thanks for the link, I'll take a look at the iRiver port.
