    Hi there,

    thats the same problem as in your other post, your path variable is not correct.

    Again for me its:

    PATH=$PATH:/opt/altera9.1sp2/quartus/bin/

    you obviously have a big problem with your environment variables. Chech all your Quartus installation, find out where all the Quartus and Nios executables are, and check that your environment variables are correct.

    hello,

    my variable PATH is

    usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/root/bin:/opt/altera9.1sp1/quartus/bin:/opt/altera9.1sp1/quartus/linux:/opt/altera9.1sp1/nios2eds/bin

    so do you think in this PATH there is any problem ?

    or i should add any things ?

    What are the contents of LD_LIBRARY_PATH, QUARTUS_ROOTDIR and SOPC_KIT_NIOS2 ?

    You also seem to be missing the path to the GNU tools (something like /opt/altera9.1sp1/nios2eds/bin/nios2-gnutools/H-i686-pc-linux-gnu/bin)

    I am getting this same error while trying to download a Linux image, except it seems a little bit intermittent.

    The download was working, then it wasn't. Then it failed the first time but succeeded on the retry. After that, it worked for a while, but then failed again. For what its worth, the time it failed and succeeded on the retry was using Windows. Most of the time, I have been using Linux.

    The quartus tools and USB drivers seem to work this time, but they can't find the CPU in the FPGA.

    Did you configure the FPGA with the proper .sof image first?

    The .sof file is in the flash. However, even when I try to download it using 'nios2-configure-sof', I still have trouble running with the 'nios2-download'.

    I was able to briefly regain good performance after running this same sequence on the Windows partition. Eventually, it started failing on the Linux side with this same error.

    Are you sure it is the exact same .sof file in both cases? I fail to see why the CPU wouldn't respond when you try to access it from the linux machine.

    When you run nios2-configure-sof on the silux machine, are you sure everything goes well? No error?
