DE2-70 Control panel 连接FPGA失败
[/img] 有可能是Control panel版本的问题，换个版本试试吧~ 应该是quqrtus ii 用新于7.0的版本，找不到下载路径，以下是解决办法如下：I Found the solution using DE2_70_control_Panel in Quartus 9 !!!
The problem is that all de directory paths of Quartus and NIOS have changed. Consecontly, the soft don't know where are basics softwares.
to use the soft, you must downlad the config (.sof) and the ssram .elf manually. After, just do connect in the control_panel software.
1) load the .sof manually using programmer tool.
2) use nios2 shell command :"H:/altera/90/nios2eds/Nios II Command Shell.bat"
3) in this console window, go to the Control_panel directory (the path hase the form /cygdrive/<niosdrive/.....
4) execute : nios2-download DE2_70_Control_Panel_ssram.elf -c USB-Blaster -r -g
4 remark) I can put this line in file (example toto) and after call "bash toto" in the console.
5) execution tell you that the .elf is loaded
6) execute the control panel soft
7) if you want to use the FLASH MEM, you must Erase it as soon as possible before executing any thing
