C6747 FLASH烧写程序后，仿真器连接不上

检查一下boot管脚, boot [7,2,1,0,3]是否设成了11110, emulation debug mode, 具体见下面的文档第27页上的Table 6.

您好，我们使用spi0 flash boot mode，相应的boot管脚为0101X，烧写的程序以前也用过在其他的板子上~

补充一下，仿真器连接错误提示：

Error connecting to the target:

是不是DSP烧坏了？

你将boot [7,2,1,0,3]设成11110,  接仿真器,  boot管脚要设成emulation debug mode

印制电路板上的boot[3]没有引出，只将boot [7,2,1,0]设成1111，可以不？ps：以前调另外一块板子也烧写过flash，之后也可以正常连接仿真器在线调试的呀，能给解释下吗？

另外一块板子的电路和这块一样吗? boot管脚设置一样么? OBSCLK管脚clock正确么?

现在还能连另外一块板子吗? 试试重新安装一下仿真器驱动程序.
