TDA2: IVAHD encoder sample application hangs at H264ENC_create

Mayank Agarwal

Part Number: TDA2

I am trying to generate the encoded output file by running the TI ivahd encoder sample application TestAppDM816x/TestAppOmap4

on TDA2PX evm board but the application hangs at

handle[insChanid] = H264ENC_create((H264ENC_Fxns *)&H264ENC_TI_IH264ENC,
&gParams[insChanid]);

I haven't modified any encoder configuration and i am running the default application.

On suspend the running i am seeing the following error message in diassembly window:

Memory map prevented reading 0xFEF4000C [code=0x20000]

Any workarounds so that i should be able to generate the output file.

Hi Mayank,

Can you please single step through the code to localize where inside the H264ENC_create you are crashing?
Typical reasons for a crash would be access to a memory space which is not mapped/understood by the CPU core.

Thanks and Regards,

Hi,

It is hanging in AlgInit function.Currently i am trying to run it on A15 core.

Is there any procedure to run the sample application on multiple core or any other particular core.
I tried running it on m4_0 and m4_1 core but with both it is giving similar results.

Has anybody tried successfully running it.Please write in detail the procedure.

Regards
Mayank

Hi Mayank,

I think you will have modify the Base address in \codecs\h264enc\app\test\inc\h264enc_ti_config.h The existing is for OMAP4 & NETRA.

#define M3_HZ change this;//(250000000)

#define MEM_BASE_IVAHD0 change this;//0xBB000000
#define REG_BASE_IVAHD0 change this;//0xBA000000
#define RST_CNTL_BASE_IVAHD0 change this;//0xAA306F10

Hi Prashant,

Thanks for your mail.You mentioned in your mail that the above macros needs to be changed.

Currently i am working on TDA2PX evm board,what would be the correct values of above macros for the evm that i am using.

Mayank

Hi Mayank,

The base address will be present in the TRM of this target. Do you have the TRM?

Hi Mayank,

The TRM is at http://www.ti.com/lit/ug/spruif0a/spruif0a.pdf

The addresses would be

#define MEM_BASE_IVAHD0 change this;//0x5B000000
#define REG_BASE_IVAHD0 change this;//0x5A000000
#define RST_CNTL_BASE_IVAHD0 change this;//0x4AE06F10

Hi Prashant,

Thanks for your continuous support.

In the TRM that i am having for TDA2PX evm in the iva subssytem following lines are mentioned:

NOTE: The IVA-HD subsystem is a set of video encoder and decoder hardware accelerators. The
list of supported codecs can be found in the software development kit (SDK) documentation.
The IVA-HD subsystem availability is device part number dependent. Refer to device Data
Manual, for more information

I could not find the register settings that you have mentioned in the TRM.
Are you sure that these register settings will fix the crash issue.

Regards
Mayank

Hi Mayank,
Please refer the above post from Piyali on the Address you need to set. I have not tried running the sample testapp on TDA2PX. But to run this code on different targets we will be using respective Base address. So, theoretically it should work.

Hi Prashant,

Thanks for your continuous support.I configured the register settings as suggested by Piyali

but i am getting the same crash at H264Enc_Create.

Hi Mayank,

Can you tell me the detailed procedure you followed to run this on TDA2PX? It would help to debug further.

Hi Mayank,

We have not heard back from you on this one. I assume you were able to move ahead. Please let us know if otherwise. The thread would be closed automatically if there is no reply.
