TDA2PXEVM: eglError shown on terminal

Praveen Thomas

Part Number: TDA2PXEVM

i had used the following usecase,

NullSource (A15) -> Decode -> VPE -> Alg_FrameCopy (A15) -> SgxFrmcpy (A15)

// display on m4
SgxFrmcpy -> Display_M4 (IPU1_0)

when i connected the Alg_FrameCopy to SgxFrmcpy and to Display_M4 i got the following error

PVR:(Error): OpenServices: PVRDRMOpenRender failed [0, ]
PVR:(Error): PVRSRVConnect: Unable to open connection. [0, ]
PVR:(Error): Couldn't connect to services [0, ]
EGL: eglInitialize() returned 0
EGL: after eglInitialize() eglError (0x3003)
ASSERT (sgxFrmcpyLink_drv.c|SgxFrmcpyLink_drvDoProcessEglInfo|225)
[HOST] [HOST ] 48.777770 s: EGL: version -1225733452.11
[HOST] [HOST ] 48.777801 s: EGL: eglInitialize() failed !!!

Can anybody tell the reason for this error ?

Hi Praveen,

SGX kernel module seems not inserted.

Can you check this command?

lsmod | grep pvr

Thanks

Hi Praveen,

Are you building kernel from vision-sdk? If you are using make linux and make linux_install , the sgx kernel modules will also get built and installed.

make sure the filesystem has these two kernel modules pvrsrvkm.ko and bc_example.ko in

lib/modules/4.4.84-xxxxxxxx/extra/

Thanks

Hi Praveen,

Which version of vision-SDK is used here? The target filesystem has a file etc/init.d/rc.pvr which is the script in usermode to load the required sgx modules.

Can you try to load the modules manually from the root prompt ?

Thanks
