I know nothing about this but here's what I did tonight to get this going (its failed many times in the past for me!)
- Downloaded https://rcn-ee.com/rootfs/bb.org/testing/2016-10-09/lxqt-4gb/bone-debian-8.6-lxqt-4gb-armhf-2016-10-09-4gb.img.xz - Burned a card, booted and grew the partition. Rebooted. - Ran sudo ./update_kernel.sh --bone-rt-kernel --lts. Rebooted. - Installed the correct Linux headers Now, for the SGX I followed the instructions at http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black but they didn't work. I ended up with a '.bin' rather than a tar file, in a dl folder but there was no deploy folder. Anyway, I had done this a few months ago and saved the tar file from then. I installed that tar per the instructions. Then I followed the instructions at https://groups.google.com/forum/?hl=en&fromgroups#!msg/beagleboard/sOhHuq_T6KQ/xDeaoWyeBgAJ;context-place=msg/beagleboard/D-lhg28O5m4/yqRTbZPFDQAJ, namely:- sudo apt-get install ti-sgx-es8-modules-`uname -r` sudo depmod -a `uname -r` sudo update-initramfs -uk `uname -rcode here... Rebooted. The result: Last login: Fri Oct 14 19:27:03 2016 from 192.168.1.66 debian@beaglebone:~$ lsmod | grep omaplfb omaplfb 12048 0 tilcdc 28057 1 omaplfb pvrsrvkm 147997 1 omaplfb debian@beaglebone:~$ glxgears 26 frames in 5.0 seconds = 5.161 FPS 54 frames in 5.1 seconds = 10.644 FPS 54 frames in 5.0 seconds = 10.700 FPS 54 frames in 5.1 seconds = 10.670 FPS 54 frames in 5.0 seconds = 10.709 FPS 54 frames in 5.1 seconds = 10.670 FPS 54 frames in 5.0 seconds = 10.707 FPS 54 frames in 5.1 seconds = 10.670 FPS 54 frames in 5.0 seconds = 10.704 FPS ^C debian@beaglebone:~$ uname -a Linux beaglebone 4.1.34-bone-rt-r24 #1 PREEMPT RT Thu Oct 13 03:42:46 UTC 2016 armv7l GNU/Linux debian@beaglebone:~$ I think this is a complete account, I hope it helps.
