how to build hdvpss from source code

Hi,

HDVPSS source code is not packaged with ezsdk. So you wont be able to re-build db816x_hdvpss.xem3. What is the requirement for rebuilding .xem3.

Hardik Shah

thanks for your reply.

Yes, HDvpss source is not included in ezsdk, but I have gotten an additional package from TI and installed it successfully.

I think the pre-built image *ONLY* can be run on EVM board, it can't fit all requirements for all customs' board. For example, if the video input decoder (TVP*) were changed to other devices (such as ADV7604...), The HDVPSS firmware will be needed to changed and the whole image need to be rebuilt . Another requirement is that we want to use HDVPSS as a hardware accelerator for mem2mem loop-back processor  (*NOT* for input/output, for example, several pictures in memory were send to HDVPSS for down-scaling and blend some GUI, and then the blended picture will be write back to memory ) .

So, I think I need to rebuild the source code firstly, and then I need to coding for my requirements.

thanks

So, as you mentioned, we can NOT use current version hdvpss image for our product at present, since the ADV7604 can't be supported by current HDVPSS.

I have followed HDVPSS_UserGuide.pdf to build hdvpss, the build progress works well. But the built image can NOT be run on the EVM board (system hangs as described in the original question).

thanks

Hi,

If you have source code for HDVPSS, you can add support for ADV7604 in HDVPSS source and you can use it.

Is image hanging after your changes or even if you build without changes it hangs.  It should not hang if you are building without any changes. Can you please send me the steps you are following to load .xem3 and other drivers.

I agree that we can support by adding source code into vpss firmware. So, my first step is to build the vpss source code without any change.

I just build and replaced build/ti816x_hdvpss/bin/ti816x-evm/ti816x_hdvpss.xem3 to target file system /usr/share/ti/ti-media-control-utils/dm816x_hdvpss.xem3.

The init script "etc/rc5.d/S15load-hdvpss-firmware.sh" will load the firmware in next boot.

I have debug the system. it hangs in syslink driver (shaking-hand with M3), so it seems M3 fail to startup with my image, but can startup with prebuild image:

*******************************************************

Int32
Platform_startCallback (UInt16 procId, Ptr arg)
{
    Int32 status = Platform_S_SUCCESS;
    Platform_ModuleConfig slaveModuleConfig;

    GT_2trace (curTrace, GT_ENTER, "Platform_startCallback", procId, arg);

    do {
        status = Ipc_attach (procId);                
    } while (status < 0);

    /* Get shared region max numEntries from Slave */
    do {
        status = Ipc_readConfig (procId,
                                 SLAVE_CONFIG_TAG,
                                 (Ptr) &slaveModuleConfig,
                                 sizeof (Platform_ModuleConfig));
    } while (status == Ipc_E_FAIL);

......................

***************************************************

please note that the file size is much difference between the two image.

I listed what I have as blow:

1) all source code of ti-ezsdk_dm816x-evm_5_02_01_59

2) source code of hdvpss_01_00_01_28

What package do you think I missed? I really want to know the build env when TI build the prebuild image.

thanks

I noticed that there is no OMX included in my Rule.make

  CODEGEN_PATH_M3 := $(workspace)/media-controller-devkit/cgt470_4_9_0
  hdvpss_PATH := $(workspace)/component-sources/$(hdvpss_RELPATH)
  bios_PATH := $(workspace)/component-sources/bios_6_32_01_38
  xdc_PATH := $(workspace)/component-sources/xdctools_3_22_01_21
  ipc_PATH := $(workspace)/component-sources/ipc_1_23_03_31

So, there is NO OMX linked in my image, my build is just a proxy server example. Could you tell me which package include the OMX component for HDVPSS?

it seems that "ti-ezsdk_dm816x-evm_5_02_01_59/component-sources/omx-ti816x-src_05_02_00_15" is the OMX package for hdvpss, does it?

velan

it seems that "ti-ezsdk_dm816x-evm_5_02_01_59/component-sources/omx-ti816x-src_05_02_00_15" is the OMX package for hdvpss, is it?

I have built it successfully!!

thanks Velan !

Now, we use SDK that is 'ti-ezsdk_dm816x-evm_5_02_01_59'.  I think that it is same.

We have source code that is HDVPSS-01.00.01.28

Our environment don't exist  'omx-ti816x-src_05_02_00_15'.  but 'omx_05_02_00_15' exist.

'omx_05_02_00_15' are the same as 'omx-ti816x-src_05_02_00_15'? If different, we want to get  'omx-ti816x-src_05_02_00_15'.

I too have that query - from where can we get  'omx-ti816x-src_xx_xx_xx_xx' ?

and it is not same as omx_xx_xx_xx_xx, because it is not containing the source files for the OMX  plugins for codecs (vdec, venc etc).
