Hello, TI experts !
I tried running theod andseg demos in thedl_demos directory , but they failed during execution. The error message is as follows：

I feel confused,because I have successfully run these two demos before.Does this have anything to do with the fact that I have changed the display parameters? My display initialization parameters are as follows:
if(VX_SUCCESS == status){memset(&displayObj->disp_params, 0, sizeof(tivx_display_params_t));displayObj->disp_params.opMode = TIVX_KERNEL_DISPLAY_ZERO_BUFFER_COPY_MODE;//TIVX_KERNEL_DISPLAY_BUFFER_COPY_MODE;displayObj->disp_params.pipeId = 2; /* pipe ID = 2 */displayObj->disp_params.outWidth = DISPLAY_WIDTH;displayObj->disp_params.outHeight = DISPLAY_HEIGHT;displayObj->disp_params.posX = (1920-DISPLAY_WIDTH)/2;displayObj->disp_params.posY = (1080-DISPLAY_HEIGHT)/2;displayObj->disp_params_obj = vxCreateUserDataObject(context, "tivx_display_params_t", sizeof(tivx_display_params_t), &displayObj->disp_params);status = vxGetStatus((vx_reference)displayObj->disp_params_obj);if(VX_SUCCESS == status){vxSetReferenceName((vx_reference)displayObj->disp_params_obj, "display_node_disp_params_obj");}}
My modification was changing thepipeid from 0 to 2, but now even if I change it back to the original value, the demo still fails to run.
My sdk version is 09_01_00
I hope to get your help.
Best regards,
