After a couple of months of on and off again work building on what was started by bakercp and others I have had some success in getting openFrameworks running on the pcDuino. At this stage I have it setup to use a framebuffer.
Instructions that should be allow you compile and run a pcDuino Hello World application similar to the one for the Raspberry Pi are posted on my blog.
I am interested in any feedback and will do my best to assist in resolving problems. Please post them as comments on the blog entry or follow ups to this post.
