# Board description
The SAMA5D3 Xplained is a fast prototyping and evaluation platform for **SAMA5D36 Cortex-A5 Microprocessor**. The board comes with a rich set of ready to use connectivity with1x SD/eMMC and 1x MicroSD slots and expansions headers (Arduino DUE, 3.3v Uno R2 & R3, and Mega R3 shield) compatible for easy customization. A Linux distribution and software package gets you evaluating fast. A USB device connector can be used to power the board as well as programming and debugging it.

# Test results
The Yocto Project releases in the table below have been tested by the Mender community. Please update it if you have tested this integration on other [Yocto Project releases](https://wiki.yoctoproject.org/wiki/Releases?target=_blank):
| Yocto Project | Build | Runtime |
| --- | --- | --- |
| thud (2.6) | :test_works: | :test_works: |
**Build** Means that the Yocto Project build using this Mender integration completes without errors and outputs images.
**Runtime** Means that Mender has been verified to work on the board. For U-Boot-based boards, the [integration checklist](https://docs.mender.io/devices/integrating-with-u-boot/integration-checklist?target=_blank) has been verified.
# Getting started
## Prerequisites
- A supported Linux distribution and dependencies installed on your workstation/laptop as described in the [Yocto Mega Manual](https://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#detailed-supported-distros)
- NOTE. Instructions depend on which Yocto version you intend to use.
- Google repo tool [installed](https://hub.mender.io/t/google-repo/58/2) and in your `PATH` .
### Setup Yocto environment
Set the Yocto Project branch you are building for:
```auto
# set to your branch, make sure it is supported (see table above)
export BRANCH="thud"
```
Create a directory for your `mender-atmel` setup to live in and clone the
meta information.
```auto
mkdir mender-atmel && cd mender-atmel
```
Initialize repo manifest:
```auto
repo init -u https://github.com/mendersoftware/meta-mender-community \
-m meta-mender-atmel/scripts/manifest-atmel.xml \
-b ${BRANCH}
```
Fetch layers in manifest:
```auto
repo sync
```
Next, initialize the build environment:
```bash
source setup-environment atmel
```
### Building the image
You can now proceed with building an image:
```auto
MACHINE=sama5d3-xplained-sd bitbake core-image-base
```
Replace `core-image-base` with your desired image target.
### Using the build output
- `tmp/deploy/images/sama5d3-xplained-sd/core-image-base-sama5d3-xplained-sd.sdimg`
- `tmp/deploy/images/sama5d3-xplained/core-image-base-sama5d3-xplained-sd.mender`
The disk image (with `.sdimg` suffix) is used to provision the device storage for devices without Mender running already. Please proceed to [the official documentation on provisioning a new device](https://docs.mender.io/artifacts/provisioning-a-new-device?target=_blank) for steps to do this.
On the other hand, if you already have Mender running on your device and want to deploy a rootfs update using this build, you should use the [Mender Artifact](https://docs.mender.io/architecture/mender-artifacts?target=_blank) files, which have `.mender` suffix. You can either deploy this Artifact in managed mode with the Mender server (upload it under Releases in the server UI) or by using the Mender client only in [Standalone deployments](https://docs.mender.io/architecture/standalone-deployments?target=_blank).
