Will EZSDK xem3 files work for DM8165?

We have a board with DM8165 processor. Linux and Frame Buffer Video are working fine.

When we try to run the H264 decode examples from EZSDK

/usr/bin/runDecodeDisplayHDMI

in /mnt/p2/tiroot/usr/share/ti/ti-omtb/

omtb_dm81xxbm_a8host.xv5T fread_vdec_fwrite.oms

omtb_dm81xxbm_a8host.xv5T decode_scale_display.oms

It seems that the call back from H264 display code is not being received.

The memory map is the same as that on DM816x Eval Board.

xem3 files are stripped version of xem3 files used in DM816x.

Would the EZSDK xem3 code that runs on DM8168 run on our DM8165 board or is a modified xem3 firmware necessary?

Hello,

The codec are running on HDVICP module.
DM8165 has 2 HDVICP modules.
The DM8165 has 3 HDVICP modules.

You could check here:

Thanks. The question remains though

Will the EZSDK xem3 firmware that is written to run on DM8168 with 3 HDVICP2 modules run, as it is, on our DM8165 board with 2 HDVICP2 modules?

This depends on the xem3 firmware I think - does the xem3 firmware automatically detect the number of HDVICP2 modules and adjust itself to accordingly, or is the number of HDVICP2 modules hard coded inside the xem3 firmware.

Hello,

Could you try to run omx dispay demo this should work since it is not using hdvicp module.

If you have the overlay package you could check ivaschedulerint.h for IVA_SCHEDULER_N_IVAID and change 3 to 2.

Margarita:
If we have a NDA with TI we should be able to get overlay package from FAE , right?

We need the hardware acceleration for performance reasons. We need to decode many streams of H.264 data,

Thanks

Hello,

The overlay package is under NDA and you should contact your local FAE.

Note: I have not tried the modification for DM8165.
