Hello, The original patch still needs to get merged into CVS. I think Brian Austin at Cirrus finally got the information sent off to FSF. Hopefully that process does not take forever... I have been maintaining a local branch of the port for my use for quite a while. It's current to the last CVS update I did on 9/16/2009. The port works fine but my source would need some cleanup in order to get merged into the CVS, mostly for style issues. I have looked at implementing a gpio system for the ep93xx. I'm just not sure where this would go into ecos. I have also cleaned up the SPI access functions in the Ethernet driver and started looking at a true SPI driver. I did dump all the Cirrus pkgconf files a while back and just put in what I needed for my board. The original files will need to be added back and cleaned up. Most of my changes to the original port were done simply because I couldn't follow what Cirrus was doing ;-). My need is only for RedBoot but I would be glad to help with anything that I can. A lot of ecos I really don't "get" so bear with me... If you want I can send you a diff of what I have right now. It might not all be "right" but RedBoot does at least work. Regards, Hartley
