The patch [1], which is required for DRM to work properly, has been merged into Linux version 5.14-rc3. There's a 5.14.12 now in stable, so I took that one. After Linux boots, /dev/fb0 will be accessible. You can control the brightness of the display after enabling the framebuffer by running the following commands: ~ # echo 0 0 > /sys/class/graphics/fb0/pan ~ # echo 255 >/sys/class/backlight/40016c00.dsi.0/brightness The brightness ranges from 0 to 255, as you can see running the command: ~ # cat /sys/class/backlight/40016c00.dsi.0/max_brightness [1] 24b5b1978cd5 ("clk: stm32f4: fix post divisor setup for I2S/SAI PLLs") Signed-off-by: Dario Binacchi <dariobin@libero.it> --- board/stmicroelectronics/stm32f469-disco/linux.fragment | 8 +++++++- configs/stm32f469_disco_defconfig | 4 ++-- 2 files changed, 9 insertions(+), 3 deletions(-)
