| 摘 要： | 利用JTAG烧写Flash的方法是通过并口把PC与主控芯片的JTAG连接,PC向Flash的特定地址发出控制命令,把烧写的目的数据、地址和控制信号经JTAG TDI串行输入到对应的边界扫描单元.调用putp函数转换TAP状态,更新引脚状态后从系统总线输出到JTAG,即完成烧写操作.

| Abstract: | The way of burning flash on board by JTAG was that PC is connected JTAG of the host controller on board with parallel port, and then PC sent control command to the address of flash, and burned data and address and control signal was inputted to corresponding boundary scan cell by JATG TDI. The state of TAP was switched with function putp, and after flash was updated by JTAG to output into JTAG from the bus of system. At the same time, the JTAG of host controller receive the data to complete the operation of burning flash. |
