Getting Started with a Gateworks SBC

Welcome! Thank you for purchasing a Gateworks single board computer (SBC). We hope to get you started with a little bit of info from our Gateworks wiki site.

Gateworks single board computers (SBC) are powerful, low power network processor boards that are unlimited in their capabilities.

Thihs getting started wiki page will document how to power on the Gateworks SBC and connect to a serial console command prompt. The great news is, all Gateworks SBCs ship with Linux pre-installed!

We highly encourage you to utilize this wiki (How to Use Gateworks Wiki) after getting your single board computer turned on with the step by step instructions below.

Required Items

To get started and get connected to your board you will need:

1. A development host machine, such as a laptop or desktop, preferably a Linux machine such as Ubuntu. Windows will also work.
2. Gateworks Single Board Computer
3. Power supply (there are many options here, please use the supply sent with the development kit to get started)
4. JTAG USB Programmer - not required but VERY helpful. Used for programming board and serial console access. (Included in development kit) More info on JTAG here
5. Operating Manuals are also available online at ​https://www.gateworks.com/products/ on each specific product webpage under the documentation tab
6. Latest firmware, is available to download from ​http://dev.gateworks.com/. After verifying your newly purchased board will boot, be sure to update its bootloader and GSC firmware to the latest version.

dev.gateworks.com and the Gateworks GIT repo

The prebuilt images on dev.gateworks.com are based on our latest source code. If you would like to see the change logs these can be found on ​our Github page. Click the repositories tab, search for the board family name, select the repo you're interested in, then click "commits". Each commit has a note about what changes were made, also a diff in the source code can be viewed.

Physical Connections

There are two main connections to the single board computer ( SBC ).

1. Power
2. Communication

Power

• Most Gateworks' boards support voltages between 10VDC - 48VDC. Please consult the operating manual.
• If a development kit was purchased, a 12V or 24V DC Wall supply is included that will connect to the power connector barrel jack on the GateworksSBC. * Note on the GW5910, please only use the power supply with the PoE Injector *
• Some boards require a 2 pin specialty connector with an adapter. Silkscreen labels are often labeled VIN for voltage input.
• POE is possible on certain models. 802.3af is available on certain models. Passive POE between 10-48VDC is often supported. Please consult the user manual. POE Information

Communication

• USB JTAG Dongle (included with development kits, or sold separately ​JTAG Purchase Link
  • This JTAG Dongle device is necessary for serial console access.

Example Configuration: (Note in picture below, JTAG Adapter (14 to 10 pin) likely is not required. Connect directly straight to the SBC)

First Steps

Steps to get to a command prompt on the board:

1. Setup Serial Console on Host PC
   • Please go through the setup instructions for connecting the USB JTAG Programmer to a Host PC.
     • Linux Serial Console instructions
     • Windows Serial Console instructions
2. Connect: the communication cables from the Host PC to the Gateworks SBC, such as the JTAG cable or an ethernet cable or serial cable.
3. Start console program (configured in step 1, such as baud rate, etc)
4. Connect power to SBC
5. The board will start outputting text out of the serial console.
   • Yocto OS Login: root
   • Ubuntu Username: root
     • Ubuntu Password: root
   • See example picture below:

6. Now that functionality has been verified, follow our jtag instructions to update to the latest boot and GSC firmware. Without the latest firmware some features of the board may not function properly.

Next Steps

Now that you can login to the board, the options are unlimited! Start using the Gateworks board for your intended use!

There is lots of great information on the Gateworks Software Wiki homepage pointing to many examples, hints, tips, and tricks!

Please use the search box in the top right hand corner as well!

Product Manuals are also available online at ​http://www.gateworks.com/usermanuals which contain very helpful information.

Ubuntu Linux is typically installed by default, but often OpenWrt is another option.

• JTAG: Flash your board with binary image from a binary listed in step above or the one you compiled using a USB JTAG Programmer and these JTAG Instructions
• TFTP Ethernet: as detailed here (bootloader specific):
  • Newport Family
  • Ventana OpenWrt Specific
  • Laguna OpenWrt Specific
