❤♡与JTAG连接问题
❤♡在用一块板子,上面有一块EPM7128STC100-10,在上电后可以工作,现在想改里面的程序,但用USB-BLASTER怎么也连接不上,在编程串口弹出“Unable to scan the JTAG chain.Can't scan JTAG chain. Do you want to open the JTAG chain debugger to troubleshoot the JTAG chain? ”
下载时,在主窗口中有“Error (209001): JTAG ID code specified in JEDEC STAPL Format File does not match any valid JTAG ID codes for device
Error (209012): Operation failed”
查找网上,一般说是JTAG焊接问题,但经过测量各引脚都是接好的啊求问一下这是怎么回事啊???
