Hello all, I'm hoping someone might have some insight to this problem. We are working with a prototype HW design based on the OMAP35xx, very similar to the BeagleBoard design. We are using an LCD panel and normal framebuffer graphics are working great. We would like to use vector graphics acceleration, so we are trying to get the demos in the OMAP35x_Graphics_SDK_3_0_0_6 running but we're getting stuck on an error from the PowerVR library. Unfortunately we don't have source for this library so we're in the dark as to the cause. Here's what we've done so far.
1) Installed the OMAP35x_Graphics_SDK_3_0_0_6 on our development system.
2) Patched the graphics SDK for our 2.6.27 kernel using the 2.6.27 patch provided in the graphics SDK
3) Built the training course example under GFX_Linux_SDK/OVG/SDKPackage/TrainingCourse/01_Initialization
4) Built the kernel modules under GFX_Linux_KM
5) Loaded the kernel modules on our target (they load without errors)
6) /etc/init.d/rc.pvr start for the PVR initialization
7) Ran the 01_Initialization example program built in step 3.
When we run this program, we receive the following error from the PowerVR library:
PVR:(Error): *** PVR2D Blt via 3D Core *** [425, devices/sgx/pvr2dinit.c]
At this point in the example program, eglCreateWindowSurface() fails and the program exits. I don't see any errors from the kernel modules in dmesg. I also instrumented the kernel module code from GFX_Linux_KM with debug information about the status of all calls and they are all fine. The problem is somewhere in the PowerVR library but that error message doesn't tell us much. Oh, one other thing, we are using the non-X version (NullWS). Has anyone else encountered this? Thanks for any help or insight.
