We never got to the bottom of Dan's issue though, and I tried suggesting disabling the other outputs. Lukas' dt files only have HDMI output, so much like the SR Hummingboard setup - but that seems to work fine (although I don't have any iMX6QP devices, only iMX6S, D, Q and possibly a DL.) -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
