If the Wikipedia page on ARM 11 is to be believed (http://en.wikipedia.org/wiki/ARM11), then even the original Nvidia Tegra uses this architecture, but aside from the Raspberry Pi I am not aware of any ARM11-based platform out there which might be useful for ROS, unless someone wants to run it on a smartphone.

I think at this point one has to look at the features provided by the ARMv6Z architecture and see whether it suffices for ROS's ARM port. If it's too much of a bother to work around issues, then don't use it.

I thought Windows supported v5 – v7?

 

Anyway, I realise that the Raspberry Pi uses the dated v6 architecture, but the killer thing here is the $25 price tag.

There’s also the BeagleBoard which is slightly cheaper than the PandaBoard, and also uses the A8/v7 chip. But at $149 I really don’t see it shifting the same number of units as the raspberry boards. I already know quite a lot of people who are wanting to personally buy quite a few for fun and potential uses.

 

Maybe the development effort for a v6 port isn’t worth it, but I think it’s worth keeping an eye on the sales figures because the demand for these things seems huge. Potentially, that’s a large number of developers which might be attracted to reactos.

It's a generation-lagging ARM11 -- Windows and iOS don't support these kind of chips anymore (called ARMv6) because of major lacking functionality. The ARMv6K (which I'm not sure the Pi uses) is probably the minimum you'd want to use, and I know the ROS ARM port was retargeted to ARMv7 which has been out for almost 3-4 years now.

 

The PandaBoard, which is 179$, so definitely more expensive, is a much better platform for such a port -- it's an A9/v7 (successor to A8/v7, successor to ARMv6K, successor to ARM6...) and has dual-core, 1GB of RAM, a GPU, a DSP, and more... still a bargain for 179$ if you ask me though.

It looks like the model B boards are now in manufacture. http://www.raspberrypi.org/archives/509

There are only 10k being made being made in this batch and demand is really high, so I doubt they’ll last longer than a few minutes.

 

With only 256MB RAM available, I doubt Windows 8 will ever run on it although Windows Embedded Compact 7 might.

I know the reactos arm port is still a way off, but this could be a golden opportunity for reactos.

At $25 per computer, they’re gonna sell hundreds of thousands of these things and most buyers will be enthusiasts/developers.
