So, for over a week I have been trying to get Qt 5.3.2 working with OpenGL on a BBB with a 3.8 kernel. So far, I haven't made much progress even though I"ve spent many hours.
I am stuck just trying to get OpenGL/SGX working on the black using the TI graphics SDK. I have tried 4 different 3.8 kernels, including the official ones as well as RobertCNelson's stuff. I have applied about 10 patches to the graphics SDK and the kernel. I can get the Graphics SDK built and installed, but I keep coming back to this: [ 5.263934] PVR: PVRCore_Init [ 5.270060] PVR: PVRSRVDriverProbe(pDevice=df0c2e00) [ 5.270176] PVR: SGX register base: 0x56000000 [ 5.270189] PVR: SGX register size: 16777215 [ 5.270200] PVR: SGX IRQ: 37 [ 5.270233] PVR: EnableSystemClocks: Enabling System Clocks [ 5.270283] PVR_K:(Error): EnableSystemClocks: Couldn't get GPTIMER11 functional clock [512, opt/Graphics_SDK_4_10_00_ 01/GFX_Linux_KM/services4/system/ti335x/sysutils_linux.c] [ 5.270305] PVR_K:(Error): SysInitialise: Failed to Enable system clocks (171) [481, opt/Graphics_SDK_4_10_00_01/GFX_L inux_KM/services4/system/ti335x/sysconfig.c] [ 5.274037] PVR: PVRCore_Init: major device 240 When the pvrsvrkm driver tries to load, a "clk_get()" function fails in the driver and I cannot for the life of me figure out why? It's unclear exactly what timer this is, as the error indicates GPTIMER11, but inside the driver code it's referring to "gpt7_fck". I assume this is timer7 in the Sitara? I have recompiled several versions of 3.8 kernels many, many times. I"ve applied several patches. I have tried cutting out device tree objects and disabling many things to no avail. I have seen 3 or 4 folks who supposedly have gotten this TI "pvrsrvkm" and "omaplfb" driver to load and some of the test graphics apps to actually work....I'd really like to know how they did it? The patches I have I collected from an FSE at TI, as well as some guy named Alexander. These apply to the Graphics SDk and the kernel, but nothing I have tried seems to get rid of this clock issue? I have built the graphics SDK with make BUILD=debug OMAPES=8.x PM_RUNTIME=1 all, and left out PM_RUNTIME, which seems to affect which portion of init code in the driver is executed...but I get another clock error, so no dice! Does anyone have a 3.8 kernel with OpenGL working? I tried installing the packaged drivers with Angstrom..but had no success there either. I know TI is only supporting the 3.12 kernel...but there are cape issues there, plus I have Xenomai running with 3.8 and I hate to jump to 3.12. Anyone have any success running OpenGL on 3.8 with a bone-black??? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
