Re: [ros-dev] Rasberry Pi

[Maya Posch]

According to Wikipedia the Raspberry Pi uses the ARM1176JZF-S core which 
is an ARMv6Z architecture. It should be similar to the ARMv6K as it most 
notably lacks multi-core support. It's still an old architecture, of 
course, and I agree that the Cortex A-series is a much better choice as 
a development platform, whether it's the currently popular A8/A9 or the 
upcoming A15.
