Part Number: TDA4VM
Other Parts Discussed in Thread: DRA829,

I have just started DCC Tuning the TDA4 pipeline, there are various plugins where it is possible to upload LUT files. May i know where to get/make these LUT files from? Eg: If i Have to upload a LUT for RAWFE is there a format or example files available to edit?

    Hi Dinesh,

    Most of these luts are included in the DCC profile, provided for the selected sensor. Most of the luts contain 16bit 513 values..

    You could find more details about them in the TRM/datasheet.

    Regards,

    Brijesh

    Hi Brijesh,

    Can you please be precise about this DCC profile, where it is and how i can access it? Any folder routes? or anything in that sense?

    I have looked into the 'J721E DRA829/TDA4VM Processors Silicon Revision 1.0' document for detailed understanding about these LUT's but is it the same document you are referring here? or can you point me to that document. 

    In general terms, will the LUTs be available as files along with DCC or must it be created separately? I have understood the theory and size of each LUT details through the document, I just don't know how to create/access/edit them.

    Regards,
    Dinesh.

    They are included in the sensor driver code in PSDK s/w, e.g., "imaging/sensor_drv/src/imx390/dcc_xmls/wdr/".

    You will need to run "./generate_dcc.sh" there and recompile if you modify the files.
