BBB, how to install chipsee 7inch screen and gfx driver with lastet debian image?

hi!
i have a BBB and chipsee screen, i need a debian so with opengl es support, can anybody help me with this?
thaks for share!


i have some problem to install gfx driver in prebuild image (3.18.13 kernel)

Grab the latest image:

http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Debian_Image_Testing_Snapshots

and set /boot/uEnv.txt

dtb=am335x-boneblack-bbb-exp-c.dtb

dtb=am335x-boneblack-bbb-exp-r.dtb

Depending if you have the resistive or capacitive screen:

and update xorg for 24bit:

sudo sed -i -e 's:16:24:g' /etc/X11/xorg.conf

Regards,

thanks you robert!

We've never had x11 support for the am335x, and we NEVER will..

Rebuild qt5 with eglfs, there's a lots of guilds in this forum, that
works for opengl es...

How does one know if qt was build with eglfs. I thought that mine was but I cannot seem to get xcb working at all. It is just not available as an option when running code.
I dont have x11 support installed. Headless only.

sorry, iam a newbie.
but, why the demo does not work?

I need a working demo to try to change my code and make it work with FBdev

I'm trying to use openframeworks in a BBB

Thanks for your answers!!

Taking advantage of the thread, I would like to make a question in reference to both, Chipsee TFT & BBB.

@Damian, does your system work fine just installed?
I have followed the instructions wrote here (except the SGX ones, by the moment I’m not going further), but the touch panel does not work well even after calibration. It only works in a half-part of the screen.
What kernel are you working with? How did you calibrate the screen? Could you share the calibration file (/etc/pointercal.xinput.EP0790M09), please?

  • Also, does the speaker works for you? This is another issue I have, audio works well through headphones, but the speaker.

Hi,

I am trying to get Chipsee “Beaglebone Black Expansion (Capacitive) 1024*600 Pixel 7 Inch LCD, 5-Point Capacitive Touch” working with the latest image:
bone-debian-9.5-lxqt-armhf-2018-08-20-4gb.img

(1) uboot loads the special dtb fine:

loading /boot/dtbs/4.14.62-ti-r71/am335x-boneblack-bbb-exp-c.dtb …
57497 bytes read in 138 ms (406.3 KiB/s)

(2) xorg.conf default depth is set to 24.

However, /dev/fb0 is not created. Any idea why?

The hardware is working well with the old CD supplied software.

Please help!

Thanks, Enoch.
