Linux/PROCESSOR-SDK-AM335X: Unable to start GPU driver

Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3354

Tool/software: Linux

Hi,

We are testing the newest SDK "Processor SDK Linux 04.01.00.06" on our customize AM3354 board and found that we could not start GPU driver by "/etc/init.d/rc.pvr". It will show the following error message:

root@am335x-evm:~# /etc/init.d/rc.pvr start
PVR:(Error): OpenServices: PVRDRMOpenRender failed [0, ]
PVR:(Error): PVRSRVInitSrvConnect: PVRSRVConnect failed [0, ]
PVR:(Error): SrvInit: PVRSRVInitSrvConnect failed (4) [0, ]

(The "ti-sgx-sdk-km" is built by Yocto. We had tried to rebuild the "ti-sgx-sdk-km" manually, but it still not work.)

On the other hand, we use the same step to build the SDK "Processor SDK Linux 03.03.00.04" and there is no such problem.

Could you help to check it? THANKS.

Brian
