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?
