Setting up the hardware
=======================

The Astra Machina Foundation Series of evaluation-ready kits
enable easy and rapid prototyping for the Synaptics SL-Series of
embedded Linux and Android processors. A modular
design incorporates swappable core compute modules, a common I/O board,
and daughter cards for connectivity, debug, and flexible I/O options.
This page lists the simple steps to power on and boot up the system
and applies to all SL-Series core modules: SL1680, SL1640, and SL1620.

    Core module connections

Included in the box
-------------------

a. The Astra Machina Foundation Series system with core module, I/O board,
   and daughter card for Wi-Fi/BT connectivity

b. A 15V @ 1.8A AC power adapter (USB Power Delivery)

c. A USB-C cable (USB-C plugs on both ends)

d. An AC plug adapter (IEC Type A receptacle/Type C plug, used only if applicable)


Booting the desktop environment
-------------------------------

By connecting a monitor, keyboard, and mouse, you can run the desktop environment:

1. Connect a display monitor to the board with an HDMI cable.

2. Connect a USB Keyboard and/or Mouse to the board.

3. Optionally, plug an Ethernet cable into the board's RJ45 port for Internet connectivity.

4. Connect the AC adapter to the board using USB-C cable (IMPORTANT - ensure you use the USB-C port marked PWR-IN), and plug the AC adapter to the power outlet


.. note::

   The green LED next to PWR_IN will be lit and solid when the board is powered correctly. A flashing green LED indicates insufficient power - please use the supplied 15V @ 1.8A power adapter.


Once powered on, the Astra Machina board will boot the Yocto Linux distribution preloaded on its eMMC storage, and display the Wayland Desktop. You can now explore sample media and AI applications, open a Linux terminal from Wayland Desktop, and use the built-in Chromium browser (with Internet connectivity):

Running in headless mode
------------------------

To connect to your Astra Machina Board from a development host PC via SSH:

1. Ensure your board is connected to Ethernet and can access the Local Area Network of the host.

2. Open a terminal on the Wayland Desktop and use the following command to obtain the IP address::

      ifconfig eth0 | grep "inet addr"

3. Once you have the IP address of your Astra Machina Board , you can connect via ssh. For example::

      ssh root@10.3.10.19

You can also connect to your board using ADB Shell. Follow the instructions here: :ref:`adb_shell_guide`


Update Firmware 
-------------------------------------

It's recommended that you update your board to the latest firmware using this guide: :ref:`firmware_update_usb`
