When I was a developer, and customer, using MSDN in my day-to-day work, I occasionally found myself frustrated by document discoverability. MSDN often had the information I was looking for -- sometimes in multiple formats -- but finding just what you want in MSDN can be quite a task.
We're working to improve this situation for a number of critical scenarios, including device bring-up. One important task for board support package (BSP) developers is porting a BSP from a previous version of Embedded CE to Embedded CE 6.0. Luckily, BSP porting information exists in a number of places.
First, the MSDN Library contains information on porting BSPs, starting at: http://msdn.microsoft.com/en-us/library/aa917748.aspx. You can also find information on porting device drivers, another key device bring-up task, at: http://msdn.microsoft.com/en-us/library/aa931071.aspx.
Channel 9 has an excellent talk by Travis Hobrla of the Embedded CE team on the process of porting a BSP from Embedded CE 5.0 to CE 6.0: http://channel9.msdn.com/posts/mikehall/Porting-a-CE-50-BSP-to-CE-60-Travis-Hobrla/.
Doug Boling gave a great presentation on the new CE 6.0 kernel which includes porting information at MEDC 2006; you can find that presentation here: http://download.microsoft.com/documents/australia/medc2006/Windows_CE6_Architecture_Boling.ppt.
Please let us know if there are other crucial scenarios about which you're trying to find information!
