Differences between TDA2XX and TDA3XX

Other Parts Discussed in Thread: TDA2

Hi

I am trying to port source code that works on TDA2xx on TDA3xx.I have following doubts:

1.Master core in TDA2XX is a15 and in TDA3XX it is m4,so we have to shift all modules that are being used by a15 in TDA2XX to m4 in TDA3xx.

2.Modules on which the functionality like ethernet,camera capture depends in TDA2xx.At the bare minimum i want ethernet and camera capture functionality to be working on TDA3xx.

3.vip module uses tda2xx video driver which has 12 capture,but tda3xx supports 4 camera,this needs to be identified where all changes are required.

Regards

Mayank

    Mayank,

    You could start with Vision SDK. It already supports Ethernet, camera capture and other drivers on TDA2 and TDA3. In both cases the SW runs on the M4. On TDA2 the physical master is the A15, which will launch the secondary boot loader (SBL). The SBL will load and start the code from the M4.

    Hi Ejs,

    Thanks for your mail.I am proceeding the following steps:

    1. Take all the TI packages namely bios,starterware,edma,ipc,xdc,bsp from Vision SDK and compile them for TDA3XX.(I could do this for starterware and bsp only.For other packages are they compatible with TDA3xx as they are for TDA2XX or they also need separate compilation)

    2.Compile my application code with tda3xx toolchain.

    I still have following doubts;

    1. Will i have to shift modules running on a15 core to dsp/m4 core or simply disabling a15 compilation while compiling the application for tda3xx will work.

    2.Will tda3xx compilation require altogether different toolchain from what i was using when compiling for tda2xx.

    3.Bootloader packages will be generated from starterware module using sbl user guide and using that will boot the board.

    4.If i compile the code for dsp and m4 cores and then generate the combined disc image and flash it in tda3xx,will it work or i have to make other changes.

    Regards

    Hi Mayank,

    All TI packages are compatible with TDA3xx.
    In case you have designed your application to run some particular operations on A15, you will need to shift it to dsp/m4.
    You can refer to Vision SDK as an example.

    TDA3xx compilation uses same tool chains as TDA2xx. M4 uses TMS470, DSP uses C6000 and EVE uses TI ARP32 compiler.
    You can create multi-core application image including both dsp and m4 cores (you can follow steps given in SBL user guide) and it will work.
