Hi,
I have the beaglebone Black. I run Debian with custom build kernel. Is the latest kernel .
debian@beaglebone:~$ uname -a
Linux beaglebone 4.14.108-ti-r108 #2 SMP PREEMPT Fri Jun 28 15:28:17 EDT 2019 armv7l GNU/Linux
I use this display: LCD Display Module,2.8" 240x320 SPI TFT LCD ILI9431.
The display is working fine. I can run qt apps on the fb0 on linuxfb
QT_QPA_PLATFORM=linuxfb /lib/qt5/examples/examples/qtwidget/calculator/calculator Just perfect
Nothing seemed to works on GFX,
Here are the system details:
debian@beaglebone:~$ sudo apt-get install ti-sgx-ti335x-modules-`uname -r` Reading package lists... Done Building dependency tree Reading state information... Done ti-sgx-ti335x-modules-4.14.108-ti-r108 is already the newest version (1stretch). 0 upgraded, 0 newly installed, 0 to remove and 99 not upgraded. debian@beaglebone:~$ sudo apt-get install ti-sgx-ti335x-modules-`uname -r` Reading package lists...

Then
wget https://remi.avignon.me/bbb/libgbm_2.0.0-1_armhf.deb 743 dpkg -i libgbm_2.0.0-1_armhf.deb 744 sudo dpkg -i libgbm_2.0.0-1_armhf.deb 745 wget https://remi.avignon.me/bbb/omap5-ti335x-sgx-ddk-um_1.0.0_armhf.deb 746 dpkg -i --force-all omap5-ti335x-sgx-ddk-um_1.0.0_armhf.deb 747 sudo dpkg -i --force-all omap5-ti335x-sgx-ddk-um_1.0.0_armhf.deb 749 sudo /etc/init.d/rc.pvr start 750 ps ax | 751 ps ax | grep pvr 752 wget https://remi.avignon.me/bbb/kmsxx_1.0.0_armhf.deb 753 sudo dpkg -i kmsxx_1.0.0_armhf.deb
Results
fbtest OK (ignore the rotation)
