@Robert Nelson SGX modules not found in latest Robert Nelson image 8.7

[Gurpartap Singh]

I am using latest image bone-debian-8.7-lxqt-4gb-armhf-2017-03-19-4gb.img
Then I followed the link: http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black

./sgx_create_package.sh and installed the tar.gz package from deploy folder to BeagleBone.
But After Rebooting Board when I do :
lsmod | grep omaplfb
there is no such module.

Please suggest me something.I have some questions:
1.Is it necessary to compile kernel with SGX modules or these are built in above said downloaded Image?

[Gurpartap Singh]

I followed Steps like:
./build_kernel.sh
./sgx_build_modules.sh
./sgx_create_package.sh
sh tools/install_kernel.sh

But I found strange thing that When I :
modinfo pvrsrvkm.ko
it is showing vermagic:       3.14.23-00496-g0e6c1bf-dirty SMP mod_unload modversions ARMv6 p2v8
but my kernel version is 4.4.73-bone18

That's not the steps i have listed here:
http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black

Step 1: you need the v4.4.x-bone kernel, so on the Beagle you run:

cd /opt/scripts/tools/
git pull
sudo ./update_kernel.sh --bone-kernel --lts-4_4

Step 2: run the sgx_create_package.sh

git clone https://github.com/RobertCNelson/bb-kernel.git
cd bb-kernel/
git checkout origin/am33x-v4.4 -b tmp-sgx
./sgx_create_package.sh

Step 3: copy the "GFX_5.01.01.02_es8.x.tar.gz" to the Bone and run

sudo tar xfv GFX_5.01.01.02_es8.x.tar.gz -C /
cd /opt/gfxinstall/
sudo ./sgx-install.sh
sudo reboot

Look closer at modinfo's output:

filename:
/opt/github/4.4.x-lts/bb-kernel/deploy/test/opt/gfxlibraries/gfx_rel_es8.x/./pvrsrvkm.ko
license: Dual MIT/GPL
author: Imagination Technologies Ltd. <gpl-s...@imgtec.com>
srcversion: 533BB7E5866E52F63B9ACCB
alias: of:N*T*Cti,sgx*
depends:

vermagic: 3.14.23-00496-g0e6c1bf-dirty SMP mod_unload
modversions ARMv6 p2v8

That module came from imgtec, it's closed source...
