摘要
针对嵌入式系统的Flash操作方式,深入分析了基于JTAG和UART的两种Flash操作方式。基于JTAG方式的Flash操作调试程序方便;基于UART的方式程序下载、系统升级方便。以AT49BV1604A存储器和三星公司的S3C4510B芯片为例探讨了这两种方式的操作,在基于嵌入式系统的E1-以太网网络桥接器的设计中得到了较好的使用效果。
According to the Flash operation ,a in-depth analysis of JTAG and UART modes is developed. JTAG operation is used in program debug and UART operation is used in program download and system upgrade. The two modes are introduced in this paper. which have got a good effect in the design of E1-Ethernet bridge based on embedded system, and Flash. chip AT49BV1604A and ARM chip S3C4510B were used.
