To dt-fy your .config, looks like you need to add these to your build system seed config file: CONFIG_BACKLIGHT_CLASS_DEVICE=y CONFIG_BACKLIGHT_GPIO=y CONFIG_BACKLIGHT_LCD_SUPPORT=y CONFIG_CMA=y CONFIG_DISPLAY_PANEL_SHARP_LS037V7DW01=y CONFIG_DMA_CMA=y CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y CONFIG_FRAMEBUFFER_CONSOLE=y CONFIG_PINCTRL_SINGLE=y That should actually improve your setup from the current booting with the framebuffer enabled ;) I also posted the defconfig and demsg for you to diff against to: http://muru.com/for-rmk/ I wonder if the battery charger hardware is broken on your LDP? I don't think that is even being enabled in the legacy boot for LDP as it as there's no struct twl4030_bci being passed except from board-omap3pandora.c. Regards, Tony
