    Hi,

    I looked at chapter 2.1 in the NIOS II Software Developer Handbook and I had already done all 3 steps. However after step 3 there was a note shown below.

    Note: • For the Nios II Command Shell, use all command line tools, as before, but you
    need to add .exe to launch a Windows executable, like eclipse-nios2.exe or
    jtagconfig.exe.

    Therefore I typed the command "nios2-terminal.exe" instead of "nios2-terminal" and the command worked.

Hi,


Looks like you may need to debug your NIOS connection before you can play around with HDMI example design.


I found below link.


If you confirmed you have installed everything correctly then the next thing that you want to check is your on board JTAG connection

  • Pls try to reduce JTAG frequency to either 16MHz or 6MHz
  • Pls close other application if any that may consume JTAG connection bandwidth like system console, signal_tap, in system source and probe and etc
  • Also ensure you are doing direct JTAG connection to your board via USB blaster cable and not via remote JTAG connection through network


Thanks.


Regards,

dlim

    In the link above it stated that "some commands require the .exe to be granted and some do not." What does granted mean and how do you do that?

    Also how do I tell if I have installed the additional distro packages required for Nios II EDS? What are distro packages?
