Flash Prerequisites

This section provides step-by-step instructions for preparing your development host for flashing the image to the device.

Note

The following instructions assume you are using Ubuntu 22.04 LTS.

Install Git

Git is required to download the usb-tool. Follow these steps to ensure it is installed:

  1. Check if Git is installed: Open a terminal and run the following command:

    git --version

    If Git is installed, this command will output its version (e.g., git version 2.34.1). If you see a version number, you can skip to the next section.

  2. Install Git (if not installed): If Git is not installed (e.g., the command in step 1 returns an error like “command not found”), install it using the following commands on Ubuntu:

    sudo apt update
sudo apt install git

    You will be prompted for your password and asked to confirm the installation.

Set up usb-tool

The usb-tool is essential for flashing the device. With Git installed, follow these steps to set it up:

  • Clone the repository:

    Open a terminal and clone the usb-tool repository from GitHub:

    git clone https://github.com/synaptics-astra/usb-tool.git
