各位大侠,偶这些天刚买了一根USB blaster下载线,原以为可以调NIOS II了,可是还是出出如警告: nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster [USB-0]", 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) nios2-terminal: exiting due to I/O error communicating with target 这和我用并口btyeblaster ii下载线出现的红色警告是一模一样的, 我问了卖主,他说可能是我用的QUarter II版本太高了,我用的是7。1的, 从上面的提示好象是说要用B型的USB blaster II才行!!! 请问各位大侠,是这样的吗,是不是我用的线的质量太差吗,还是怎么的呢? 请用过USB 线调试NIOSII的各位帮我一下。 另外我这根USB下载线下程序是没问题的,可是在调NIOS2中 ‘HELLO_WORLD '例子时,出现上述红色警告,并且没在 调试窗口中出现“hello from nios ii !"的字样 这肯定说明USB线JATG并没把其传到主机上哇!!!! |
