I want to use the samsung panel in portrait orientation, so after much reading of this forum and some code review of the omapfb driver, I though it would be enough to add "omapfb.rotate=1" to the kernel arguments. However, the framebuffer device seems to work as expected but the GPE environment (I'm using the palmtop image) fails to initialize. This is the debug output of the omapfb driver: OMAPFB: check_var(0) OMAPFB: check_fb_var 0 OMAPFB: max frame size 262144, line size 544 OMAPFB: xres = 272, yres = 480, vxres = 272, vyres = 480 OMAPFB: set_par(0) OMAPFB: set_fb_fix OMAPFB: changing rotation to 1 OMAPFB: apply_changes, fb 0, ovl 0 OMAPFB: setup_overlay 0, posx 0, posy 0, outw 480, outh 272 OMAPFB: pan_display(0) OMAPFB: setcmap OMAPFB: pan_display(0) OMAPFB: setcmap OMAPFB: setcmap OMAPFB: ioctl QUERY_MEM OMAPFB: user mmap region start 80808000, len 262144, off 80808000 OMAPFB: ioctl QUERY_PLANE OMAPFB: ioctl SETUP_PLANE OMAPFB: omapfb_setup_plane omapdss MANAGER error: dispc_setup_plane failed for ovl 0 omapdss MANAGER error: configure_overlay 0 failed OMAPFB: ioctl QUERY_PLANE OMAPFB: ioctl SETUP_PLANE OMAPFB: omapfb_setup_plane OMAPFB: ioctl QUERY_MEM OMAPFB: ioctl QUERY_PLANE OMAPFB: ioctl GET_CAPS Any clues on how to get this working?

Carl, Thanks for you quick reply. I don't have the hardware here so I can't test right now, but the only difference I see is your dvimode environment variable. From the debugging I've been doing I doubt it's the problem. Just to have a known-good reference, could you please upload your uImage and rootfs to some file sharing service, so I can try it?

Did you guys get this working? I am dealing with the same thing now. If I run ts_calibrate or ts_test things seem to work fine after that with X & matchbox-session, etc... What is ts_test & ts_calibrate doing to make things work? John Buckley iggarpe wrote: > > Carl, > > Thanks for you quick reply.
