TDA3: How to enable RGMII1 (NDK) and MMCSD (FATFS) in VSDK 02.12.00.00?

Part Number: TDA3

Which steps do I need to make to enable RGMII1 and MMCSD in VSDK 2.12.00.00? I see e2e.ti.com/.../2210505 and do understand that MMCSD and RGMII0 does not work on TDA3EVM due to board constraints. However in case I am using the RGMII1 daughter board how can I enable FATFS and NDK?

    Hi Ewald,

    can you in file <VSDK>/vision_sdk/configs/autorules_footer_cfg.mk find the fragment:

    #
    # For TDA3xx, when NDK is enabled, FATFS cannot be used due to MMCSD conflict with RGMII0.
    # To use MMCSD and NDK together, RGMII1 daughter board needs to be used.
    #
    ifeq ($(PLATFORM),$(filter $(PLATFORM), tda3xx-evm tda3xx-rvp))
    ifeq ($(NDK_PROC_TO_USE),ipu1_1)
    FATFS_PROC_TO_USE=none
    endif
    ifeq ($(NDK_PROC_TO_USE),ipu1_0)
    FATFS_PROC_TO_USE=none
    endif
    ifeq ($(NDK_PROC_TO_USE),a15_0)
    FATFS_PROC_TO_USE=none
    endif
    endif

    and comment it out. I suspect that it sets FATFS_PROC_TO_USE to 'none' always when board is TDA3 independent of
    weather RGMII1 daughter board is used.

    Regards,
    Yordan

    The changes Yordon suggested would enable Ethernet port1.
    You would need RGMII1 expansion connector to use port1 on TDA3xx EVM.

    Prasad, Yordan,

    thanks for your suggestions. Let me rephrase my request.

    We will use the RGMII1 expansion. We need both at the same time FAT_FS and NDK? How can we enable this option?
     
     The following setting do not work. Are the any additional changes that I have to apply? Do I need to disable RGMII0 and enable RGMII1 somewhere?

    NDK_PROC_TO_USE=ipu1_0
    FATFS_PROC_TO_USE=ipu1_0

    as result File_open will fail.

    Int32 File_open(char *name, char *mode)

    {

        return SYSTEM_LINK_STATUS_EFAIL;

    }

    Hello Ewald,

    Have you remove config code as Yordan suggested from <VSDK>/vision_sdk/configs/autorules_footer_cfg.mk?

    Also can you please share output of gmake -s -j showconfig?

    Prasad, Yordan,

    thanks for your help. After I commented out it is working now.
    # FATFS_PROC_TO_USE=none
