Booting DaVinci EVM from NAND Flash (Rev. A)

Currently, the DaVinci™ evaluation module (DVEVM) supports three boot modes: the DVEVM can boot from NOR (default), NAND, or universal asynchronous receiver/transmitter (UART). NOR Flash offers the advantages of one-byte random access and execute-in-place technology. NAND Flash is not as easy to work with since it requires Flash Translation Layer (FTL) software to make it accessible; however, due to its lower price, speed, and longer life span, many costumers want to design with NAND Flash instead or NOR Flash. This application report describes the process to follow for booting the DaVinci DVEVM from NAND Flash.

Flashwriter source code is not available. If you need to customize a Flash utility for your custom board, please see the DVFlasher utility covered in Booting and Flashing via the DaVinci TMS320DM644x Serial Interface (SPRAAI4).
