I don't understand the comments here: SAMA5D4 Xplained is an embedded Linux board, you can load whatever embedded Linux you want on it!

Buildroot is supported, Yocto project is supported you can easily find and load Debian images, Android is available and OpenWRT should be piece of cake to use as well... What do you need? a R-Pi? then use a R-Pi then... sama5d4 xplained is different: you are building the community around it, not arriving with a whole world using it yet so please, do not expect the same level of documentation you won't have it.

I recall it's an embedded Linux platform, not a mini-desktop: here again don't expect the same user experience!

I'd recommended you to start with http://linux4sam.org or https://github.com/linux4sam (with a fresh linux-3.18-at91 kernel). The forum on http://www.at91.com is handy as well.

For the most adventurous, you can even test the latest linux-next kernel: the device tree file has just been included there.

Yes, a Yocto project distribution takes hours to compile, but it worth it. If you want to start quickly, go the buildroot path: it's damn so easy to use and you have your own rootfs in an hour, you can add your own application easily and your cross-compilation environment is available...

If you don't want to re-compile anything, well use the Linux4SAM demos and once your whole filesystem is re-flashed, you can use the cross-compilation SDK that are released here: SoftwareTools < Linux4SAM < TWiki

Good hacking sessions.

Same here! I will try this one later this day:

Yocto seems to be a way to long road...

Spent 3 Evenings but got me nowhere.

A quick question to everyone, is the SAMA5D4 xplained not very well explained? I can't find anything that isn't a demo. I have been going crazy to come up with a useable OS for it, I am even trying to create my own, but time is the problem. Is there any non-demo OS available? Hacking the files got nowhere, I do require direction with this. I am not new to development boards, but this is got me baffelled. I have created a Beowulf cluster from RPi's, changed the RPi to run the gpio's from Scratch language for my kids. Any advice on non-demo software?

I'm struggling with that one too. I am as far now as what [mention:6e474abc33b64a82aa78c9813503c962:e9ed411860ed4f2ba0265705b8793d05] is showing in his SAMA5D4 Xplained Ultra - Tips and Tricks #1 - Getting Displays up and Running

I can replicate his actions to load a binary to the board.

I've spent way more time that I can afford in getting an example from th AT19 site compiled.

I have downloaded sama5d4x_xplained_softpack_1.2_for_CodeSourcery_201410 from SAMA5D4 Software Package and installed loads of Tool Chains, no luck:

Atmel Studio 6.2. As yet unable to get a project up and running for this board.

From command line with make:
From ARM DS-5
From a plain Eclipse.

All 3 fail on the first directory creation:

I've been digging in the make files and googled the error till death, no resolution yet.
