NIOS II报错

friend_linfeng

You have more than one JTAG cable available so you must use the --cable option
to choose between them (or open the "Run/Run" or "Run/Debug" dialog and go to
the "Target Connection" tab).
No --cable option was provided (or you selected Automatic)


这个在NIOS II进行RUN AS时报出的错误，请问是什么问题？怎么解决？

根據我過往的經驗，應該是因為您電腦裡頭同時有存在兩個JTAG connection，所以在配置時，程式無法判別您是要透過哪一個JTAG接口來下載程序，因此會有錯誤訊息發生。

建議您可至Nios II裡頭，Run -> Run As -> Nios II Hardware -> Target Connection -> JTAG Cable，手動指定USB-Blaster，應該就可以解決問題了。
