In fsimx6-V3 / (Armstone A9) the backlight brightness is set as shown below:
cat /sys/devices/soc0/backlight_ldb//backlight/backlight_ldb/max_brightness /* gives -> 15 */
echo 15 > /sys/devices/soc0/backlight_ldb//backlight/backlight_ldb/brightness /* sets it to maximum */
- What are possible values/strings for /sys/devices/soc0/backlight_ldb/backlight/backlight_ldb/power/control ? The default is "auto"!
- How do I access Pin-24 of the LCD FI-S25S connector in order to manually switch off/on the backlight ?
