How to get Quartus II to see the DE2 board in VirtualBox.
- Connect the DE2 USB Blaster.
- Close VirtualBox.
- Settings -> USB, Enable USB Controller
- Choose USB 2.0
- Click the plus icon to add the USB Blaster.
- Save changes.
- Start VirtualBox.
Programming the board:
- Tools -> Programmer.
- Hardware Setup -> Currently Selected Hardware -> USB-Blaster Variant 2-2
Here I ran into an error: Error (209053): Unexpected error in JTAG server — error code 89.
This site here helped me get everything working: http://www.fpga-dev.com/altera-usb-blaster-with-ubuntu/. This version of Quartus is old and relies on usbfs which has been deprecated. This site has a workaround that worked beautifully. At this point I can program my board like usual. Now to find a cool project to implement.
