I have just built fresh kernel, dtb, u-boot and sgx as per RCN eewiki 
<https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-LinuxKernel>
 and 
I have also built Qt 5.6.2.
Everything is working correctly except for one problem which I do not 
understand and hope somebody could explain.

After installing sgx drivers and a reboot I have everything as per 
instructions:

lsmod | grep omaplfb

omaplfb                12356  0 
tilcdc                 26717  1 omaplfb
pvrsrvkm              157212  1 omaplfb

but my Qt Quick programs only work when run as root (sudo).

Looking at the sgx-startup script, /dev/pvrsvrkm should be set with 666 
permissions, but after startup this is what I get:
ls -al /dev/pvrsrvkm 
crw------- 1 root root 247, 0 Nov 27 20:54 /dev/pvrsrvkm

When I run:
sudo /etc/init.d/sgx-startup.sh stop
sudo /etc/init.d/sgx-startup.sh start

I get:
sgx: Starting PVR
/usr/local/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=129)
 
ls -al /dev/pvrsrvkm 
crw-rw-rw- 1 root root 247, 0 Nov 27 21:48 /dev/pvrsrvkm
Permissions are now correct for running program as normal user.

my programs run correctly with platform eglfs - which is what I want.

My questions:

1. Why does sgx-startup.sh not set the permissions correctly on boot and is 
there a way to solve this?

Thanks in advance

Rob
