Nios II 13.0/17.1烧写SOf及ELF文件不成功问题
在D盘（随意），新建一个文件夹。此处以HEX文件夹为例；将Quartus II工程和Nios ii 工程编译生成的sof和elf都拷贝到此文件夹内(D:\ HEX)；
按如下格式，新建一个txt文件，此处命名为CIS_Sensor.txt；里面内容如下：
sof="xxxxxx.sof"
elf="xxxxxx.elf"
echo "sof>flash ..."; sof2flash --epcs --input=$sof --output=hw.flash --quiet
echo "elf>flash ..."; elf2flash --epcs --after=hw.flash --input=$elf --output=sw.flash
echo "cat flash ..."; cp hw.flash hw_sw.flash; cat sw.flash >> hw_sw.flash
echo "flash>hex ..."; nios2-elf-objcopy --input-target srec --output-target ihex hw_sw.flash hw_sw.hex
echo "del flash ..."; rm -f *.flash
注意sof="xxxxxx.sof" ，elf="xxxxxx.elf"的名称用你生成的文件名替换
保存CIS_Censor.txt,然后更改后缀命名为CIS_Censor.sh(sh文件，bash的批处理文件；类似于DOC的bat文件)
打开开始>程序>Altera>Nios II EDS xx.x>Nios II xx.x Command Shell，此处以Nios II 13.0 Command Shell做示范
输入命令：cd D:/HEX (此命令是切换到你.sh文件夹下，懂一点点LINUX命令的都知道的)
输入命令：./CIS_Sensor.sh(此命令是执行.sh文件)
命令运行完后会生成hw_sw_.hex文件
打开QII>File>Convert Programming Files（图2），添加刚才生成的hw_sw_.hex ，把SOF Data给Remove掉，然后点Generatehw_sw_.hex生成jic。
最后通过Quartus ii 的Programmer直接下载jic，重新上电，一切OK。 附上Nios ii 13.0C:\Users\winter\Pictures\Screenshots\屏幕截图(8).png烧写不成功的图片 Error: 0 bash 6256 find_fast_cwd: WARNING: Couldn't compute FAST_CWD pointer.Please report this problem to
