I am working with AIO-3399J and DM-M10R800
I compiled with rk3399-firefly-aio-linux-lvds.dts
and I checked lcd_pwr_en is high , VDD-CORE is 1.2V , lcd_rst is high, 1.8V
and I checked LCD Board VGH =>5.59V , VGL=>-5.6V
AVDD=>11.2V ,VCC_LCD=>3.2V, LED+ => 4.97V, LED- =>0.0V
But LCD backlight is not working. tured off.
what position should I check?
I want to turn on LCD
