Design of Secondary Bootloader for Embedded System based on DSP

摘要

This paper desirables the secondary bootloader based on the TMS320C6713B which connected with external 16 bit width FLASH memory. The secondary bootloader design is one of the difficulties in the project development of the embedded system based on DSP. The paper briefly introduces the EMIF and FLASH chip features. Then the hardware interface design is given. The linker command options are used to create boot copy table and the secondary bootloader for large-scale program code is designed. The last, the paper introduces the process of all the design steps. The result shows that the paper offers the method of the secondary bootloader is convenient and useful. This method not only can be used in the TMS320C6713B but also can be used in the otherTMS320C6000s.
