![]() You will need to fit a 2x5 pin 1.27mm male header, as shown in the picture below, on the right. On the Sparkfun SAMD21 breakout board this SWD header is present but unpopulated as shown in the picture below, on the left. To program a SAMD21 board with OpenOCD you will need to connect that programmer to your board with the SWD header. On the Mac, we suggest using homebrew to install the different tools described here. On Debian Linux, you will use your package manager (e.g. You will need to install some software packages to program your SAMD21 board. In terms of hardware, this article also assumes you own an Atmel ICE programmer. It features the popular Atmel SAMD21G18 ARM Cortex M0 and our examples should work with little or no modifications on similar platforms such as the Arduino M0 or the TAU featured in the previous version of this article. To illustrate SAMD21 programming, we will use a Sparkfun SAMD21 dev breakout board as our target. This updates a previous blog entry with more details and minor corrections. When you hit the “Install Now” button, you’ll see a warning that you are about to delete the data.These notes describe how to program a SAMD21 breakout board with the Atmel ICE, using the command line on Mac OS X or Linux Debian, without Atmel Studio or any other IDE, or even any hardware abstraction library. If there are other operating systems installed, you may get the option to install Ubuntu along with them in dual boot.īut since your goal is to only have Ubuntu Linux on your entire system, you should go for Erase disk and install Ubuntu option. The most important screen comes at this time. You can update Ubuntu later as well without any issues. You may uncheck it because it may increase the installation time if you have a slow internet. If you are connected to internet, you’ll get the option to download updates while installing Ubuntu. You should go for the normal installation here because it will install some software like music player, video players and a few games. Choose the most appropriate ones for your system.
