This document describes the functionality of the TMS320DM647/DM648 ROM bootloader software. The ROM bootloader resides in the ROM of the device beginning at ROM address 0x00100000. The ROM boot loader (RBL) implements methods for booting in the listed modes. It reads the contents of the BOOTCFG register to determine boot mode and performs appropriate commands to effect boot of device. If an improper boot mode is chosen or if for some reason an error is detected during boot from a slave device, the RBL communicates this through the universal asynchronous receiver/transmitter (UART) as a default boot device. Note that the ROM bootloader requires use of an Application Image Script (AIS) as the primary data format for loading code/data. AIS is a Texas Instruments, Inc. proprietary data format. AIS is explained in detail in Section 2 of this document.
