Hi,
We are trying to run SGX demos on our custom AM335x Board.We successfully build Graphics_SDK_4_08_00_01 for Am335x.
Also, we generate base,console and qte image using OpenEmbedded and Arago Distro.
We can successfully run SGX demos on our base image.
When we try with your tisdk-rootfs-am335x-evm.tar.gz image (for MATRIX GUI) which comes with SDK 05.05.00.00.
It doesnt work and you can see console flow below;

[ 425.248229] Disabling lock debugging due to kernel taint
/usr/local/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=130)
When we run ;
cat /proc/sys/kernel/tainted
It says 4096 and it means An out-of-tree module has been loaded.
Why it gives such error for tisdk-rootfs-am335x-evm.tar.gz?
Why it doesnt give such error for our base-image (which we use OpenEmbedded and Arago Distro to create)?
Finally, when we run rc.pvr restart, it says, it has problems about omaplfb modules.What should we done next?
root@am335x-evm:/# /etc/init.d/rc.pvr restart
ERROR: Module omaplfb does not exist in /proc/modules
Warning: Could not unload omaplfb
