Program loading of TMS320C6000 series DSP after power on is somewhat complex. In order to make it easier, the technique of bootloader design for this series DSP is introduced in this paper. That is, the DSP program is stored in an external ROM or FLASH. After power on reset, it is booting up from FLASH, and running in internal RAM and external RAM (SDRAM). Firstly, as an example, the booting method of TMS320C671X series DSP and the process of FLASH booting are illuminated. Secondly, some approaches of second booting program are detailed discussed, and an easiest way of design and maintenance is given, that is "the booting copy table". Thus an automatic boot loading is accomplished. This technique has been used in some microwave measurement instrument.
