We have just released final v4.0 firmware for Tahoe-II and a new SDK to go along with it. This is what you need to get v4.0 working with the latest Microsoft release. Download it here.
Why should you look at 4.0? Apart from some nice new features, there have been a lot of small changes in both the Microsoft code and our code, which adds up to a faster and more stable product.
This Microsoft blog post has all the details on features and changes in 4.0, as well as download links for their new SDK.
We have Tahoe-II firmware available now, but expect to see support for our other boards (including the original Tahoe) in the next week. Once that is done, we will be finishing up a Board Support Package (BSP) so you can work with the Porting Kit on Meridian and Tahoe.
UPDATE: v4.0 firmware for Tahoe, Tahoe with Ethernet add-on board, and Meridian/P is available now.
UPDATE: v4.0 firmware for Meridian/P with the Ethernet board is now available.
