Hi
I have a BB white and a 7inch BB-View display that I got working with the 3.8.13 kernel using the instruction in this thread:
[How-to] BB-View on latest Debian
My goal is to get QT Quick 2 working on BBW, so I need the SGX-modules for the OpenGL ES2. I used the RobertCNelson scripts and used the 3.12.13-bone12 version, all successfully compiled and up working, except for the BB-View. When I try to transfer the steps from the thread above I can't get the display working. At start I get "of_resolve: Could not find symbol 'ocp'":

I found a page (Converting Device tree overlays to Kernel 3.12 on BeagleBone Black | Thing-Printer.comThing-Printer.com) about this problem and changed the "ocp" string to "baseboard_beaglebone" in the BB-View dts file. Recompile and now I got kernel panic instead, of course it wasn't that simple 
. Any help?
