Quartus Prime FPGA USB-Blaster Problems On Ubuntu 18.04

Sun, 12 Jan 2020 00:00:00 +0000

I’ve decided to learn how to program FPGA:s. So I got myself two Terasic boards, one Terasic DE10-Nano for testing out the excellent MiSTer FPGA hardware arcade/computer/console emulator and a simpler DE0-Nano for beginning to learn Verilog.

But the software used, called Intel Quartus Prime 19.1, is truly horrible. The Windows version doesn’t work with high-resolution screens when using scaling; the text is cut off on the display. So I installed it on my Linux Ubuntu 18.04 machine instead. Now the display works, but there’s a lot of other problems, like getting the dreaded error message: “USB-Blaster unable to scan device chain”. I’ve written them down here for later reference, and maybe you have the same install problems, so this might help.

Ubuntu Server WordPress with W3 Total Cache install

Initial installation Ubuntu Server

Last time I configured my web server with Ubuntu Server, I had problems finding all the instructions on what and how to install everything needed to get a WordPress blog with W3 Total Cache, CDN, Apache2 MPM Worker and fcgi working. So this is my attempt to write down the steps needed to get the server going. You might find it of interest if your needs are similar to mine. Here’s the requirements for my WordPress blog.

Apache MPM Worker threaded version
APC PHP Opcode optimizer
All the required modules for W3 Total Cache
Graphics libraries for Mint statistics

Web server with SSD disk

SSD

My old web server built on old spare parts had a hard disk crash a month ago. So I had to put it up on my BlueHost account while waiting to get hold of a new disk. I decided to try out a SSD disk, so I got hold of a 60gb IBM SSD disk. Without any optimizations, it can now handle double the traffic! I’ll continue to optimize tomorrow to get the most out of it. I’m doing an article on how to set up a LAMP server on Ubuntu Linux for WordPress with all the stuff needed to get W3 Total Cache, APC and other stuff working, because I can’t find a good article that describes everything. I will start writing on it tomorrow.
