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.
