I've followed the same test procedure: - Check out kernel v4.10-rc2 - Compile the kernel with the CONFIG_CMA_ENABLE.txt you have provided - Disconnect the VGA and HDMI cables - Turn the power on to the Lager board, let it boot - Plug the HDMI cable - Run 'bmap /dev/fb0 hdmi.bmp' with the hdmi.bmp file you have provided The output on the display is fine, identical to your 'VGA_Image.jpg' picture. At this point I believe the key difference between our setups is the HDMI monitor. Could you please send me the output of modetest -M rcar-du with the HDMI cable plugged ? -- Regards, Laurent Pinchart
