Linux/PROCESSOR-SDK-AM335X: HDMI LCD says "Please wait..."

Hello,

Could you try to restart the matrix GUI and weston:
#/etc/init.d/matrix-gui-2.0 stop
#/etc/init.d/weston stop
#/etc/init.d/weston start
#/etc/init.d/matrix-gui-2.0 start

BR
Margarita

Good morning,

I have tried your instructions.  The screen state did not change.  It still says "Please wait..."

I ran ...

#tail /var/log/weston.log

...and  I got...

[timestamp] set mode failed: Invalid argument

... a ton of times.

Is it trying to set the display to a mode the display doesn't support?

Thanks,

Nathan

I did some more poking around the forum and found a similar issue here...

e2e.ti.com/.../1927840

So I gave that stuff a try, here is the output...

(I'm not sure if triple quotes works to make this a code block or not...)

Once I ran this, I did get an Arago project banner on the display.
