Hi,
Fire3 boots normally (althrough both LEDs constantly lights ON) with image
s5p6818-friendly-core-xenial-4.4-arm64-YYYYMMDD.img.zip.
I can connect via serial console and over ssh.
Now the problem is that on LCD-S430 (from Fire3 Starter Combo with 4.3" Cap-Touch LCD)
there is no any image (only backlight is on).
How I need to configure settings in Linux to use LCD-S430 for Qt5?
Now after following commands
no any changes on LCD and command seems hangs.
Below you can find some settings and output from dmesg during boot.
Some output from dmesg:
In dmesg:
So, what is wrong with my (default) settings now?
How I can fix that?
PS. May be I need to change lcd=HDMI720P60 to value appropriate for my LCD model?
Regards,
Michael

So, what is wrong with my (default) settings now?

PS. May be I need to change lcd=HDMI720P60 to value appropriate for my LCD model?
