It has long been regarded that the UNIX-like OS NetBSD is portable to every type of machine except perhaps your kitchen toaster. Technologic Systems, however, has conquered this last frontier. Using the rugged, embedded TS-7200 single board computer housed inside the empty space of a standard two slice toaster, Technologic Systems has designed a functional NetBSD controlled toaster.
From the Archives: This article was resurrected from our white paper archives from back in December of 2004. Principles presented should be long-enduring, but there may have been some changes in the NetBSD/Linux/Unix marketplace since.
NetBSD is very similar to Linux (and actually can run Linux binaries), so you may be asking yourself why one would choose to run NetBSD instead of Linux? I will list the most common general reasons cited that apply to specifically to embedded systems designers. Wasabi Systems also has a very well written write-up describing Linux vs. NetBSD and even a guide for OEMs migrating from Linux to NetBSD.
Here’s a quick how-to guide straight from one of our engineers on how to compile the mainline Linux Kernel v4.9-rc1 and install it on the TS-4900. Support for the TS-4900 in the mainline kernel image (v4.9 and up) is a pretty big deal for us, and we’re excited about it. A big shout out to our friends at Savoir-faire Linux for their hard work in making this happen!
Step 1: Install the Toolchain
We need to install the toolchain from Ubuntu or Debian Jessie by running the following command:
apt-get install gcc-arm-linux-gnueabihf build-essential lzop u-boot-tools libncursesw5-dev -y
