BeagleBoard Support

I'm using a BeaglebBone Black Wireless. I install Debian linux on it and successfully installed NanoDLP on it. I'm facing an issue now with having the display overridden by NanoDLP display.
Currently, I get a terminal instead of NanoDLP images display.

Any idea how can I manage to fix this issue?

Correct framebuffer address on the setup page.

Re: BeagleBoard Support

I've been doing some research concerning this task and I have already read a thread in the forum concerning framebuffer value
I have run the command

"fbset -v"

And received the following output

Linux Frame Buffer Device Configuration Version 2.1 (23/06/1999)
(C) Copyright 1995-1999 by Geert Uytterhoeven

Opening frame buffer device `/dev/fb0'
Using current video mode from `/dev/fb0'

mode "1280x1024"
    geometry 1280 1024 1280 1024 16
    timings 0 0 0 0 0 0 0
    accel true
    rgba 5/11,6/5,5/0,0/0
endmode

So as the message shows, I used "/dev/fb0" as the value for framebuffer but this also didn't work.
From NanoDLP side, the logs shows the following

Error    0    2018-07-16 09:52:33.569219    Framebuffer    Custom channel implementation. 16 {0 5 0} 5 6 5

I'm not sure what this means, but I've also tried to do it on different displays/projectors which also failed

The command

ls -l /dev/fb*

only returns

crw-rw---- 1 root video 29, 0 Jul 16 09:48 /dev/fb0

As far as I'm understanding, the expected behavior after running NanoDLP (run.sh file), the terminal screen should turn black and only display images executed by NanoDLP, Am I right?
And If yes, any idea what the error returned means and how to fix it?

Re: BeagleBoard Support

Are you sure display you are using is 1280*1024? If yes, change resolution on the setup page too.
