[ros-dev] ReactOS On ARM/Raspberry Pi

[Zachary Gorden]

Guys, we have a wiki page: http://www.reactos.org/wiki/ARM_Port

The ARM team explicitly states that the ARMv4 and ARMv5 MMUs are
incompatible with ROS. They used an ARMv7 chip but do not mention if
ARMv6's MMU is of the same type as v4 and v5. Check that first before
you expend any more time/effort into this.
