Download the bootable image

Obtain the bootable image or operating system files for your desired platform.

Note

For Axon, you can download the bootable image from the Downloads page.
The bootable image is available in the SD-card section.

Write the image to the SD-card

Warning

Make sure you have selected the correct SD-card before writing the image.
Writing the image to the wrong SD-card will erase all the data on the SD-card.

You can use any disk imaging tool such as Etcher or Win32 Disk Imager to write the image to the SD-card.

For demonstration purposes, we will use the Balena Etcher tool to write the image to the SD-card.

  1. Open the Balena Etcher tool.

../../../_images/balena-start.webp

  1. Click on Select Image and select the image file.

../../../_images/balena-select-image.webp

  1. Click on Select Target and select the SD-card.

../../../_images/balena-select-storage.webp

  1. Click on Flash to start writing the image to the SD-card.

../../../_images/balena-start-flash.webp

  1. Once the writing process is complete, click on Done.

../../../_images/balena-flash-complete.webp

  1. Open the terminal and run the following command to write the image to the SD-card:

sudo dd if=/path/to/image of=/dev/sdX bs=4M status=progress; sync

Note

Replace /path/to/image with the path to the image file.
You can use the lsblk command to list the available disks.
In the above command, sd**X** is the name of the Storage drive.
`X` is the number of the Storage drive, it starts from a.

  1. Wait for the writing process to complete.

  2. Once the writing process is complete, Safely eject the SD-card from your computer.

Boot from the SD-card

After writing the image to the SD-card, follow these steps to boot from the SD-card:

  1. Safely eject the SD-card from your computer.

  2. Insert the SD-card into your Axon SBC.

../../../_images/axon-sdcard-boot.webp

  1. Power-on the device to initiate the boot process from the SD-card.

Connect the PD cable to the Axon SBC and the PD adapter to the power socket. Once the power is connected, the board will automatically turn on.
