    Hi Yong,

    You can start with the DRA71x Technical Reference Manual (TRM) chapter 33. Initialization. Then search for section 33.3.7.4 NAND. You can find useful data there regarding the NAND boot.

    For schematic design you can refer to the EVM CPU board schematic. Keep in mind that ROM boots always from chip-select CS0. Note that there are few hardware muxes you may not need in the field design.

    I think there exist a practical appnote with the tools required to generate and load NAND image. I hope other E2E guys will help with the appnote and toosl location.

    Regards,

    Stan
