Welcome to the world of embedded development. Some boards are easy, some require a fair bit of knowledge to get working.

Mostly because nobody has shepherded it into mainline. Most people are using the Xilinx drivers, but the xilinx drivers as-is aren't really suitable for inclusion in mainline (style/layout/conventions don't match). Until someone is able to dedicate a fair bit of time to get the Virtex drivers sorted out, the situation is unlikely to improve. > > Another interesting point is that the GIT development tree of montavista for > ML403 is 9 months old ....

It also guarantees that if someone provides you with a binary image, then you get access to the source code also with all the rights granted by the GPL. It does *not* compel someone to give you a copy of their source/binaries if they don't want to distribute them to you. Free refers to freedom to use it, *not* free cost. That being said; all the components you need are available in the open without cost, but it requires some effort to piece them together. g. -- Grant Likely, B.Sc. P.Eng. Secret Lab Technologies Ltd.
