Part Number: TDA2


Hi,

In Vision SDK, the linkercmd files are autogenerated. If I need to add a new section or edit the existing sections how to do it?

Regards,

    Hi Navin,

    You require to change bld file to add a new section and then inform about the new section to the BIOS. Then you could redirect the data structure to these memory section.

    You could refer to HDVPSS_DESC_MEM data section. It creates a new memory section of 2MB size, which is used for storing HDVPSS descriptors.

    hi
    for example,
    <1>
    to add/modify a section refer file - \vision_sdk\apps\build\tda2xx\mem_segment_definition_bios.xs
    <2>
    to redirect the data structure to these memory section (for core IPU1-0) - refer file \vision_sdk\links_fw\src\rtos\bios_app_common\tda2xx\ipu1_0\Ipu1_0.cfg
    for DSP1 - refer \vision_sdk\links_fw\src\rtos\bios_app_common\tda2xx\dsp1\Dsp1.cfg

    regards, Shiju
