Author: adrian Date: Tue Aug 28 06:17:44 2012 New Revision: 239765 URL: http://svn.freebsd.org/changeset/base/239765 Log: This is an initial board configuration for the D-Link DIR-825 dual-band 802.11n router. The flash layout defaults to a 1 MiB section for the kernel so I'm trying very hard to squeeze a minimialistic (LZMA compressde) kernel image into that. I've verified that it boots through to single user mode fine. Issues: * USB doesn't yet work as a module - I need to add something else to the USB AR71xx build before that will work. * There's no switch PHY support - but for now it quite happily behaves as a useful dumb switch out of the box. Phew. * Since a previous flash attempt trashed my radio configuration block, I haven't yet verified whether the wireless works correctly. I'll test that out shortly (read: once I re-calibrate the board somehow.) Thanks to ray@ and the zrouter project for doing some of the initial hard work in figuring out how to bring this board up.
