Linux/TDA2EVM5777: Problem on using SGX

Part Number: TDA2EVM5777

Tool/software: Linux

HI, 

I am using SgxFrmCpy link in custom usecase.

I added usecase in Vision_sdk/apps/src/hlos/adas/ path.

When SgxFrmCpy link create function was called, the bellow error message showed.

[HOST] [HOST ] 52.212499 s: EGL: version 1.4
[HOST] [HOST ] 52.220886 s: EGL: GL Version = (null)
[HOST] [HOST ] 52.220917 s: EGL: GL Vendor = (null)
[HOST] [HOST ] 52.220917 s: EGL: GL Renderer = (null)
[HOST] [HOST ] 52.220917 s: EGL: GL Extensions = (null)
PVR:(Error): [ 845-> 904] < gbm_pvr_bo_create_common():260|ERROR> Failed to allocate DBM buffer: Operation not permitted [0, ]

Could you suggest any solution?

Regards,

Yoo
