To start off, Atmel SAMA5D4 Xplained is a powerful little board. Actually, to say it is a little board is not necessarily true, as it is one of biggest Atmel development boards that I own. This is certainly not a bad thing, as the board contains an abundance of headers and external connectors. It sports the Arduino Mega pinout, which makes porting Arduino designs a breeze. The standard pinout is also very useful when evaluating board, because it can be used to prototype a single shield design on multiple platforms. The board also contains headers for the Xplained Pro expansion boards, which was useful for pulling over designs from previous Atmel projects. Even though I didn't use it for my project, the board also contains HDMI output, which would lend itself to a number of cool...

I applied to road test the Atmel SAMA5D4 Xplained Ultra board in order to complete a proof of concept design for a kiosk. I had prior experience with TI Sitara family of processors as well as general knowledge of Linux. However, I did not have any experience with Atmel processors or with the Yocto embedded image build environment. So, there was a fairly steep learning curve to get started developing for this board. Atmel, in my opinion, hasn't done a very good job helping potential customers across this learning curve even for engineers with some prior experience with embedded Linux processors. In the end, I was only able to partially reach my goal working in my free time over the two month evaluation period. Here's the test plan that I outlined when I applied to road test the...
