Boot.ini file for Odroid C1+ with 800 X 480 touch screen

Post by rooster3_2000 »

I was requested to print my boot.ini file here from the touch screen site. Copied below is the boot.ini file:

Try changing vout_mode to "dvi" from "hdmi" if your 800x480 display doesn't work.
setenv vout_mode "dvi"

I changed the the "setenv vout_mode" to "dvi" and all I get is a white screen. When "setenv vout_mode" was set to "hdmi" I got a black screen. The screen is using the HDMI output from the Odroid. Is it possible that this screen will not work with the Odroid C1+?

It is hard to know what is wrong since we don't have the same display.

Can you take a picture of your display rear side?

Can you read the part number of the HDMI receiver IC?
It seems to be a TI's DVI converter IC.

I do not see any marking on the IC located next to the HMDI receiver.

There must be a marking on the Quad flat package (the largest IC on the board).

The big IC is a Texas Instruments TFP401APZP. I was able to get number of the chip by the HDMI receiver with a magnifying glass and it is ATMLH722.

Since TFP401 can accept DVI signal only, the vout_mode parameter must be 'dvi'.

Try this Ubuntu OS image to narrow down root causes. You need to edit boot.ini file too.
