Quartus programmer start failed - Quartus programmer start failed Hi, I'm new to FPGA and I'm using a MAX10 starter kit and Quartus Prime Lite V23.1 to learn. The kit is identical to this one , with a MAX10 10M08DAF256C8GES FPGA, a digital display and a JTAG-USB connector. Following this project I downloaded the source code, compiled it without errors, then clicked on "Programmer". The window already opened with a hardware detected, which I assume was auto-detected from my USB port that is connected to the FPGA board. I then click on "Start" and nothing happens. The progress bar is stuck on "Failed". pringles chip for scale. I have no idea how to debug this. Is there any error log message somewhere? Am I forgetting to do something in the process? Thanks for any help. Replies: Re: Quartus programmer start failed Hi, thanks for the help! I managed to make it work... I had already tried the /etc/udev/rules.d suggestion before and it didn't work alone, but after stumbling upon this (which is pretty similar to what you suggested) I uninstalled the program as I had done several times before, but this time downloaded a new installer from " Multiple download " instead of from " Installer (new!) " in the download page . I also rebooted my computer after installation (not sure if needed). Now it works. I suspect the usbblaster driver is not installed via the installer but is via the "setup.sh" script that comes with the tar file. I am not sure, though, and I didn't find anything with "sudo lsmod | grep usbblaster". I also dont find anything with "jtag" in "systemctl list-units" but I do find a process spawned by executable jtagd which seems to be from systemd: marco@hivemind:~$ ps aux | grep jtagd marco 4917 0.0 0.0 0 0 ?

Could be a Linux specific problem as discussed here https://furrah.github.io/usb-blaster-linux-quartus2-virtual-machine/ Regarding jtagd question, Quartus instally a jtagd running under systemctrl. If it's stopped, Quartus programmer and other tools using jtagd are starting there own local jtagd instance. Replies: Re: Quartus programmer start failed I found more information on the quartus main window system log: " 209053 Unexpected error in JTAG server -- error code 89 209012 Operation failed " Looking on the web, it seems Quartus should have started a jtag server in my system, maybe "jtagd". I could not find anything like that on systemctl list-units results. Shouldn't that have been installed with quartus?
