nios II 9.1运行提示Pausing target processor: not responding.

yf.x

按照Nios II IDE 9.1的帮助文档做hello from Nios II“的练习，最后一步run as nios ii hardware时报错，提示：Using cable "USB-Blaster [USB-0]", device 1, instance 0x00
Pausing target processor: not responding.
Resetting and trying again: FAILED
Leaving target processor paused

而用run as nios ii instruction set simulator就没问题，何解？？？？

正解：

范例默认的引脚分配针对Altera的板子，非de2.so需要修改。
