Dear Expert and Support,
I'am a newbie in FPGA programming. I've tried to make an example with nios2. As you can see in the picture follows, I can do with create-this-bsp, but with create-this-app, I can not. So how can I fix this error?
Thank you for your help!
The following solution helped me:
Created a new environment variable in Windows:
After restarting Eclipse and Quartus it worked.
If it does not help, try to independently execute this command in the created directory (DirectoryName, not DirectoryName_bsp) and send a screen here.
I was having the same issue. First I couldn't create the bsp. After some googling, I found I also needed to enable the VirtualMachinePlatform and Microsoft-Windows-Subsystem-Linux features as well as install Ubuntu 18.04 LTS onto my machine. Once I finally won that fight, I ran into the issue described above where I couldn't create the app. Following Latriny's advice I added that environment variable to the system and it FINALLY worked correctly for me.
