[Shield Tablet Android Development] Steel01:
I have a few more things to report. First, to do with booting and kernel command line parameters (using 114). If I boot with nothing added, it boots with the expected upside down portrait, but with no kernel messages until the boot system initializes the video driver. If I give only console=tty1, I get the same except with correct kernel message output. If I then add fbcon=rotate:3, I get my preferred landscape orientation with everything working. I added the fbcon=map:10 during one boot and that killed the kernel message output with some errors, but the system still booted. I'm guessing that's what fbfix is supposed to fix, but I haven't tried it. But what is that fbcon map supposed to be fixing?

Kinda related and maybe useful to others: abootimg (and maybe mkbootimg) lets you specify kernel command line parameters when you pack a boot image. I've set the ones I want and wrote that image to my recovery partition. Now I can boot with proper orientation and all without having to use fastboot.

My other report deals with HDMI. etienne51, how did you get yours to work? Mine spits loads of hdcp errors. And the tv I'm testing with supposedly supports it. Why do manufacturers have to cater to all those stupid attempts at DRM and break things that paying users want to do?[/sidetrackpetpeeve] Anyways, the last couple iternations of the dmesg output is below. If you google the error, some patches are around to give a switch to disable nvhdcp. Maybe those will be worthwhile to pull into a new build. I'll try on another tv and a monitor tomorrow. Maybe I'll have better luck then.
