| Abstract: | ROM boot load is widely applied to TMS320C64X DSP system.Start-up sequence using ROM boot is analyzed,and some methods to realize the secondary bootloader is introduced.Program with BIOS or No-BIOS is used generally in C64X system.Copy table which is needed for the secondary bootloader is produced based on BIOS system and No-BIOS system.Then the Flash programming process in system is shown,with the formats of hex file produced by hex6x explained.Through lots of experiments,it is verified that the reliability and practicability of this method are better. |
