New ContributorIntel FPGA monitor_host connection issue
Hi,
You shouldn't have to manually specify javaw.exe every time. I assume that you are using Windows. Are you running the monitor program from the Windows shortcut that was created by the installer. If yes, what is the "Target" of that shortcut (ie. what is the shortcut trying to run). It should be something like: 'C:\intelFPGA\16.1\quartus\bin64\jre64\bin\javaw.exe -Dsun.java2d.noddraw=true -jar C:\intelFPGA\16.1\University_Program\Monitor_Program\bin\Altera_Monitor_Program.jar'
Kind regards,
Blair

New ContributorHi!
Thank you so much! Thanks to this, the problem of running the monitor program was solved. But still, the "host connection" problem is not resolved. I don't know why it doesn't recognize Cable.
Can you help me more about this?

Hi,
Thank you for the screenshot, it is very helpful. It seems that the monitor program is not getting the correct path for Quartus. It's getting c:/altera/quartus/ isn't quartus installed at c:/intelFPGA_lite/16.1/. Do you have two versions of quartus installed? What path is set in the environment variable 'QUARTUS_ROOTDIR'? I think you might need to fix it.
Kind regards,
Blair

Quartus was 16.1 and only one was installed. The monitor program was originally installed to 16.1, but due to the same problem, I upgraded to 18.1. When installing the monitor program, it was installed as it was because the program automatically set it to "c:\altera" in the item asking for the installation path. Today, while installing 16.1 again, I changed it to "C:\intelFPGA_lite" and installed it, but the phenomenon is the same. How do I change the QUARTUS_ROOTDIR setting? Please gave me the detail guide.
Regards.

Hi,
A guide to editing environment variables is here: https://www.architectryan.com/2018/08/31/how-to-change-environment-variables-on-windows-10/
However, running Quartus should update the environment variable automatically. You can use the steps in the link above to view your environment varaibles to make sure that it is set properly.
Kind regards,
