感谢caopengly之前的答复，我是准备在SRAM上跑，可是不行，而且又有新情况 我晕阿，到底要我怎么样呢？ 我用ByteBlasterMV在sram上run的时候，它提示我，要用一个USB的，如下： nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "ByteBlasterMV [LPT1]", device 1, instance 0 nios2-terminal: Warning: The JTAG cable you are using is not supported for Nios
nios2-terminal: II systems. You may experience intermittent JTAG communication
nios2-terminal: failures with this cable. Please use a USB Blaster revision B
nios2-terminal: cable or another supported cable. Please refer to the file
nios2-terminal: errata.txt included in the Nios II development kit documents
nios2-terminal: directory for more information. nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)
我换成了USB的，它又提示我，说没有cpu，如下，而且更可恶的是，每次运行完它就找不到JTAG了，但是用ByteBlasterMV就不会出现这样的问题，这到底是为什么啊，请指教！ There are no Nios II CPUs with debug modules available which match the values
specified. Please check that your PLD is correctly configured, downloading a
new SOF file if necessary.
