Can I use old HDVPSS firmware in new ezsdk (dm8168 platform)?

Other Parts Discussed in Thread: TVP5158

Hi,

I'd like to use the new kernel/rootfs/development kit and so on( DM8168 platform ), so I download the the latest EZSDK 5.2.2.60,

It works normally currently, But unfortunately the TVP5158 devices cann't be used, then I'd like to use other firmware of HDVPSS,

So I have two questions about it:

1. Can I use the old firmware bin of HDVPSS in newer EZSDK(that is to say, old firmware bin runs on the new software platform(kernel/rootfs/development kit and so on))?

2. How can I do next if it is doable to do that?

    Jason,

               EZSDK has not yet reached matured state to mix & match component from different releases. We also do not perform any testing in that aspect. Even it passes simple test in your setup, It is not guaranteed to will run through all test cases.

               You must always stick to component present/documented in the given release.

               Post the issues you face in the given EZSDK & get it resolved is the right approach.

    Best Regards

    Velan,

           Thank you very much.

           I had read the document of HDVPSS driver and the Memory map document, I know the reason of my problem:

           some configured info. based on variable hardware platform is built staticly in Video_M3/VPSS_M3 firmware and DSP C6accl Exectable file,

           So these info. cann't be modified by users, then they just used them and cann't do any very small modification.

     

          I think the best way is that put the configured info into a configure file, such as the I2C address/device type( TVP5158 or 7002 ) of external

          capture device, the address and size of IPC share region, the address and size  of share region among host. vpss and DSP encoder/decoder,  etc.

         all information about platform are configured  dynamicly by users,  so they can use the EZSDK tools to develop many application on variable platforms of DM8168 core,

        not only the DM8168 EVM platform,  do you think so?

     

       Regards,

      Jason Lee

    Jason,

       We understand the problem of platform varying information's hard-coded in the M3 Firmwares, which is something we are working to address in subsequent releases. Till then it is possible for customers to retrieve to source code drop for these releases and modify as per there platforms. But this needs a NDA signed.

      You could work with your local TI contact or TI FAE to get this done.

    Best Regards
