Bug ID: 13316
Summary: beaglebone_qt5_defconfig: PowerVR fails to start
Product: buildroot
Version: 2020.08
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: desmondjgood at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
Hello,
It seems like an image built with beaglebone_qt5_defconfig is broken for my
BeagleBone Black Wireless but I'm pretty new to playing around with Buildroot
so apologies if I'm missing something simple.
During the boot process, I can see a failure in the /etc/init.d/S80ti-sgx
startup script:
Starting PowerVR services: FAIL
The script attempts to load the pvrsrvkm module and then runs
"/usr/bin/pvrsrvctl --start --no-module", which then fails (or returns a
non-zero return code). Attempting to run the command manually yields:
PVR:(Error): OpenServices: PVRDRMOpenRender failed [0, ]
PVR:(Error): PVRSRVInitSrvConnect: PVRSRVConnect failed [0, ]
PVR:(Error): SrvInit: PVRSRVInitSrvConnect failed (4) [0, ]
/usr/bin/pvrsrvctl: SrvInit failed (already initialized?)
(err=PVRSRV_ERROR_INIT_FAILURE)
I've been using the following resource to help determine where my configuration
has gone wrong:
https://elinux.org/BeagleBoneBlack/SGX_%2B_Qt_EGLFS_%2B_Weston#Check_access_of_SGX_drivers
>From that, I'm thinking there's a problem with the SGX drivers since
/sys/devices/platform/ocp/56000000.sgx isn't there. I think the config is using
the TI version of the kernel and the device tree looks okay. So I'm not sure
what's wrong at this point and not quite knowledgable enough to try to debug
where it's failing further.
Any help is appreciated!
