Booting and Flashing via the DaVinci TMS320DM644x Serial Interface
This application report describes two related pieces of software that are used together to boot the ARM core of the DM644x via the universal asynchronous
receiver/transmitter (UART0) serial interface. Additionally, this software allows the user to write the needed files to a NAND or NOR flash device, connected to the DM644x AEMIF, such that the ARM core can boot from these external memories. The software consists of a host application, which runs on the user’s PC, and a user boot loader (UBL), which runs on the DM644x ARM core. This UBL also can be placed in the NAND flash memory to enable booting from this device.
