Issues with programming an Altera max 10 DE10-Lite - Issues with programming an Altera max 10 DE10-Lite I am currently trying to program my DE10-Lite for the first time, I am using the usb cable they provided with the FPGA development board. Quartus seems to recognise the USB programmer when I plug it in, since if I unplug the FPGA and programming USB cable and open up the programmer and go into hardware setup, there is nothing in the available hardware items, however if I plug the USB programming cable in with the FPGA and open up the hardware setup in the programmer it shows an option for "USB-Blaster" with server: "Local" and port: "3-1". If I select the option in the menu, I then get "USB_Blaster [3-1]" in the box next to hardware setup. After selecting the ".sof" that I would like to upload to the FPGA and pressing start I get the following output into the Quartus terminal: Info (209060): Started Programmer operation at Mon Jan 25 10:09:50 2021 Error (209040): Can't access JTAG chain Error (209012): Operation failed Info (209061): Ended Programmer operation at Mon Jan 25 10:10:20 2021 I have verified that the board is receiving power, since it is running the default program of the seven segment displays counting when it is plugged in through the USB programming cable. My question is then, do you know how I can fix these issues and program the FPGA? If there is any detail that I am missing for you to be able to answer this question, then I will be happy to provide more.

Everything seems to install fine, the usb blaster is recognized but programming fails with the same message. Note that I ONLY use USB. So it both provides power to the DE10-lite board and is also used for programming. I don't know if this is a problem. But I have found no information on how to debug this. Any help would be appreciated.
