Software Setup

Cable setup and prerequisites

Here is what you will need to power up the board:

  • Linux or Windows PC

  • HummingBoard Gate with SOM

  • 12V Power adapter (HummingBoard Gate has wide range input of 9V-36V, it is recommended to use 12V power adapter)

  • USB to UART cable

  • IP router or IP switch

Booting form an SD card

On the HummingBoard Gate it is possible to boot from different media.

For Booting from an SD card, jumpers need to be setup at J5005 as follows:

Before you set the boot jumpers, please refer to HummingBoard Edge/Gate Boot Jumpers for more information about J5005.

Once you setup the jumpers, you can apply the following for booting from an SD card.

1. Downloading the Debian image

Download the Debian image by running the following command on your Linux/Windows PC:


2. Writing the image to the SD card

Use the following commands for writing the image to an SD card:

xz -dc sr-imx6-debian-bullseye-20210904-cli-sdhc.img.xz | dd of=/dev/sdX bs=4M conv=fsync

Note: Plug a micro SD into your Linux PC, the following assumes that the micro SD is added as /dev/sdX and all it’s partitions are unmounted.

3. SD card insertion

Please Insert the SD card into your device.

4. Power connection

Connect your power adaptor to the DC jack, and then connect the adaptor to mains supply.

5. Serial Connection

Please connect the UART cable to the pins on connector J25 as shown in the below picture, then you can refer to Serial Connection for installing necessary serial connection software in Linux/Windows.

Once you installed the necessary serial connection software, you should be able to see the following:

  • In order to be able to log in , please insert “debian” as a username and password as follows:

Install to eMMC

  • You can follow this document Install to eMMC to install debian to an eMMC device.

More Features


  • Please check you Ethernet connection.

  • Use the following commands in order to keep your system up-to-date:
