I would greatly appreciate it you could do a quick write up for this thread regarding your process. Specificlly detailing which document(s) and/or instructions you followed to do the port, URLs for where these can be found, and most importantly where you departed from the starting points, and/or stumbled. We talked to Timesys and MonteVista both about this. The former sounds promising, and if they had an existing port for ML403 as a starting point we would probably just pay for their subscription service. The later did not offer a business model that was compatible with our needs. The business model can make sense for a lot of customers. We are both an ODM and a Design for Hire shop, and the model would work for some but not all of our customers/engagements. I do not intend to comment further on this. Please talk to MonteVista directly if you want to understand the business model, as I do not want to risk misadvising. We are also considering doing this without using an outside service, so your comments will be of value to me in our decision making process. If there are any consultants that have done a Linux 2.4 port to a Xilinx platform (either V2pro or V4FX, located in the greater Boston area, please feel free to drop me an email, and we'll chat offline. We might consider using an outsider to bring some of my guys up to speed, and help with our port and/or drivers. We are excited about the possibilities of Linux on V4FX. We are presently using the ML403 board as the basis for our compute platform, and intend to use Linux. I, like others, am not interested in reinventing the wheel. We are doing the initial development on our projects with ML403 and custom daughterboards. We will then build the completely custom systems. The ML403 is a very well thought out platform. Previously, we would build custom hardware before even starting the application development. For the past four years our compute platform was based on V2/microBlaze and/or V2pro/PPC with homebrewed DOS file system, and no OS. But now that we need to incorporate TCP communications and much more complicated applications support, an OS (specifically Linux) is the direction we are headed.

From: Peter Ryser on 8 Feb 2006 18:50 On the ML403 you could start with the .config file in the reference design at http://www.xilinx.com/products/boards/ml403/files/ml403_emb_ref_ppc_71.zip .. - Peter > I'd like a copy of your .config file?
