DM8168 EVM with RDK - open /dev/fb0 fiailed

BTW, do you have any plan to port PowerVR driver to RDK?

We need 3D graphic acceleration.

Hi,

Thanks for your reply.

I wrote an initializing program.

Now I can get access to fbdev.

#1

However, it makes me confused.

Is there any more simple way to initialize fbdev?

#2

I still can't get SGX530 work.

I downloaded graphics-sdk_4.04.00.03 from TI site, and recompiled kernel modules, and manually inserted them:

insmod pvrsrvkm.ko
insmod omaplfb.ko

However, the kernel reports error at the last step:

omaplfb: no symbol version for vps_grpx_register_isr
omaplfb: Unknown symbol vps_grpx_register_isr (err -22)
omaplfb: no symbol version for vps_grpx_unregister_isr
omaplfb: Unknown symbol vps_grpx_unregister_isr (err -22)

I'm sure that vpss.ko is running, but the symbols still can't be found by omaplfb.ko.

I executed service_test provided in the graphics SDK, it just returned error:

----------------------- Start -----------------------
Try calling PVRSRVConnect with an invalid argument:
 OK
Call PVRSRVConnect with a valid argument:
 FAIL - PVRSRV_ERROR_BRIDGE_CALL_FAILED

Do you have any comment about these issues?

Hi,

I cleaned the kernel & drivers, and then rebuilt them.

Now they seem to work, thanks!
