Hi Dave, To answer your question directly I have seen a proof of concept with roscpp running on a bare metal arm chip. I don't know exactly what went into making that work. Morgan, Thanks for taking the initiative to setup the SIG. I've created a wiki page for the SIG at http://www.ros.org/wiki/SIG/Embedded Tully On Wed, Sep 12, 2012 at 1:56 PM, blackstag wrote: > Hah ok will tell Paul to spell right.
