Better late than never... Big thanks go to J=FCrgen Wei=DF, who provided me with a starter patchset= a couple months ago that was enough to get the Wandboard booted to single-user mode, so I could concentrate on device drivers and general i.MX infrastructure. I'd still be struggling with this stuff without that jumpstart. -- Ian
