They recently sent one of these to me for free [1] as part of a promotion for robotics enthusiasts. It runs DFU for its boot process, they have examples for various compile system IAR/Keil etc but no explicit gcc support.<p>Looks similar to the NetDuino space although frankly I'd love to see a microSD card slot for holding stuff rather than simply relying on the on-chip flash.<p>I'd love to understand the lowest cost HDMI compatible frame buffer interface one could put on these. I've got an idea/application that I started prototyping on a Chumby which would benefit from their price point.<p>[1] <a href="http://www.st.com/internet/mcu/class/1734.jsp" rel="nofollow">http://www.st.com/internet/mcu/class/1734.jsp</a>
