    Hi,

    I believe TI does not offer schematic reviews for TMS320C6748 designs.

    Instead refer to OMAP-L13x / C674x / AM1x schematic review guidelines
    https://www.ti.com/lit/pdf/sprack9

    Since your schematics are so small I took a quick look, but not a comprehensive review. From the limited look of the partial schematics, it looks okay.

    NOR boot correctly uses CS2 in your schematics... EMA_CSn_2

    x16 NOR flash correctly connects SST39VF6401B A0 pin to C6748 EMA_BA[1].
    This matches the recommendation from SPRUH79C C6748 TRM section 18.2.5.1 Interfacing to Asynchronous Memory:

    An external pull-up resistor on NOR_CS is typically recommended.

    Weak (~51K) pull ups on all MMC/SD lines are recommended.

    Regards,
    Mark
