[ros-dev] Rasberry Pi

[Maya Posch]

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.
