摘要
简要介绍了一种新的TMS320DM642DSP与大容量Flash的接口电路设计,以及基于此设计的烧写程序的改进;详细阐述了二级bootloader的基本原理和加载过程,并针对电路改进了bootloader程序;通过对实际TMS320DM642电路的调试试验,证明了此设计的正确可靠。
Briefly introduced a new approach of extending bulk Flash memory for TMS320DM642 as well as the improvement of flash bum program. The fundamental, bootloading process and amelioration in program of secondary bootloader are discussed in detail. Debugging circuit proved the feasibility of this design.
