No worries, I should have been more precise.

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 ?
