Edge 2 firmware and support section?

Have just received a Edge2 and am having issues. The links form the product page for the forum are all 404, and there does not appear to a working firmware section. Having issues booting the board.

Is there a temporary support section that has firmware images, etc?

@Genom Sorry, because all the official documents have been replaced with new architecture documents, a large number of links in the forum have become invalid.
