我自己做了块板子,但是FPGA无法烧写程序,烧写时候显示JTAG口出问题,具体问题如下图Device:EP3C16Q240C8N
Error: The TCK and TMS connections to the device before the first detected device UNKNOWN_NO_JTAG_ID might have a problem
Info: Detected 1 device(s)
Info: Device 1: UNKNOWN_NO_JTAG_ID
请问下各位大牛,到底是什么问题呢
附JTAG原理图
TMS,TDI,TDO,TCK板上检测连接都没问题 |
