I have tested this on the 4.11.y branch, but I'm trying to get the penguins to appear. The LCD is using the 16-bit parallel interface and the backlight is driven by timer10. I have enabled the following: CONFIG_FB_OMAP2_PANEL_DPI=y CONFIG_OMAP2_VRFB=y CONFIG_FB_OMAP2=y CONFIG_FB_OMAP2_DEBUG_SUPPORT=y CONFIG_FB_OMAP2_NUM_FBS=3 CONFIG_FB_OMAP2_DSS_INIT=y CONFIG_FB_OMAP2_DSS=y # CONFIG_FB_OMAP2_DSS_DEBUG is not set # CONFIG_FB_OMAP2_DSS_DEBUGFS is not set CONFIG_FB_OMAP2_DSS_DPI=y CONFIG_FB_OMAP2_DSS_VENC=y CONFIG_FB_OMAP2_DSS_HDMI_COMMON=y CONFIG_FB_OMAP4_DSS_HDMI=y CONFIG_FB_OMAP5_DSS_HDMI=y CONFIG_FB_OMAP2_DSS_SDI=y CONFIG_FB_OMAP2_DSS_DSI=y CONFIG_FB_OMAP2_DSS_MIN_FCK_PER_PCK=4 CONFIG_FB_OMAP2_DSS_SLEEP_AFTER_VENC_RESET=y CONFIG_BACKLIGHT_PWM=y CONFIG_PWM=y CONFIG_PWM_SYSFS=y # CONFIG_PWM_FSL_FTM is not set CONFIG_PWM_OMAP_DMTIMER=y # CONFIG_PWM_PCA9685 is not set CONFIG_PWM_TIECAP=m CONFIG_PWM_TIEHRPWM=m CONFIG_PWM_TIPWMSS=y The video works fine once Linux has booted, but I'd like to see the penguins appear during the boot sequence. Otherwise, the LCD is just showing an empty screen. I am guessing some stuff is loading out of order, but I am not sure. At first I get a master bind failed: -517, but it later appears functional about 4 seconds into the boot. [ 0.992004] omapdss_dss 48050000.dss: master bind failed: -517 [ 3.854705] omapdss_dss 48050000.dss: bound 48050400.dispc (ops dispc_component_ops) [ 3.931396] omapdss DPI: Could not find exact pixel clock. Requested 5705000 Hz, got 5684210 Hz # dmesg |grep pwm [ 0.980163] pwm-backlight backlight: GPIO lookup for consumer enable [ 0.980224] pwm-backlight backlight: using device tree for GPIO lookup # dmesg |grep omapfb [ 3.943511] omapfb omapfb: using display 'lcd' mode 240x317 Based on what I am seeing, it appears as of the framebuffer and omapdss don't load until 3.9 seconds but the backlight is available almost immediately. Is there a way to reorder stuff or troubleshoot why the intial bind failed and then later worked? I am guessing that might help get the pengins working. Ultimately, I'm going to replace the penguin with a splash screen. adam -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
