Nios II Flash Programmer cannot detect USB-Blaster(Linux/Ubuntu 11.04)

Hi. 

 

I'm using Quartus II Web Edition(11.0) under ubuntu 11.04. I've met a problem that my USB-Blaster has never been recognized by nios2-flash-programmer-gui tool. 

 

Everything works fine under Windows, and nios2-flash-programmer-gui.exe can recognize my USB-Blaster cable and program the SOF and ELF file. 

 

When I do the totally same thing under ubuntu 11.04, jtagd and jtagconfig can recognize the USB-Blaster, and Programmer tool (Quartus II->Tools->Programmer) can download SOF file to the FPGA or Serial Flash through the USB-Blaster (JTAG Mode as well as Serial Programming Mode) successfully. 

 

However, under my ubuntu, When I run Nios II software build tools for eclipse, It always tells me the following error message. 

 

1. When I I click Run As->Nios II Hardware to debug my Nios II application, there's a configuration window popped-up, says: 

[Target Connection]: No Nios II target connection paths were located. Check connections and that a Nios II .sof is downloaded. 

 

2. When I click Nios II->flash programmer (to run nios2-flash-programmer-gui), I notice that the "Hardware connection" box is empty, and I cannot proceed. "Problem" box says: 

No Nios II target connection paths were located. Check connections and that a Nios II .sof is downloaded. 

 

Of course I can ensure that Nios II's SOF file has been downloaded into the FPGA before I run nios2-flash-programmer-gui. 

 

Any solutions? 

Thank you in advance. 

 

-- 

The problem has been solved after I installed the Service Pack 1(11.0sp1_quartus_free_linux.sh）, and when I ran the older one(without SP1), this problem also disappeared.  

 

Finally I don't know the reason that cause the error, as well as the reason that solve the problem.
