So OMAPFB has not found any registered displays. Try passing omapdss.debug=1, omapfb.debug=1 in your bootargs and the log would be self explanatory. > >> [ 2.180999] omapfb omapfb: failed to setup omapfb > >> > >> My bootargs are as follows: > >> > >> mmcargs=setenv bootargs console=ttyO2,115200n8 vram=12M > omapfb.vram=0:2M omapfb.mode=480x272MR-16@60 root=/dev/mmcblk0p2 rw > rootfstype=ext3 rootwait > > > > Do you have a proper CONFIG_OMAP2_VRAM_SIZE in your config? > > > I've set the VRAM to 12, but the number of framebuffers to 1. Should it be > > 1 ? > [Mayuresh]: No that should not matter. 12MB of vram for 1 FB is fine. And your bootargs state that you need 480*272*2 Bytes of memory. So 12 MB of total VRAM size is more than enough. But your bootargs state that you are providing only 2MB to FB0. Please try using omapfb.vram=0:5M. But if the problem is with the memory then OMAPFB would throw an error: Failed to allocate memory. (Yet your kernel execution has not reached there). > CONFIG_OMAP2_VRAM_SIZE=12 > CONFIG_FB_OMAP2=y > CONFIG_FB_OMAP2_NUM_FBS=1 > > > I've pasted a section of my .config file below.
