FWAuto QuickStart Guide

Get started quickly with FWAuto firmware development automation.

Installation

Prerequisites

Item	Requirement	Description
FWAuto account	Registered	Register through the FWAuto Dashboard before continuing.
uv	Latest	Python package manager
Node.js	>= 20	Includes npm, which is used to install AI CLI tools.

The installer automatically checks uv and Node.js. It skips tools that are already installed at a supported version and provides installation guidance for missing tools. Windows users should see Appendix A for the Node.js installation procedure.

Linux / macOS

curl -LsSf https://fwauto.ai/install.sh | bash

Windows

powershell -ExecutionPolicy ByPass -c "irm https://fwauto.ai/install.ps1 | iex"

FWAuto installer reporting missing uv and Node.js prerequisites

After the environment check succeeds, the script automatically installs fwauto and the required AI CLI tools.

Verify the installation

fwauto --help

Authentication

FWAuto uses Google OAuth for authentication:

fwauto auth login

Your browser opens the Google sign-in page. Select an account.
Authorize FWAuto access.
After sign-in succeeds, close the browser window and return to the terminal.

Check your authentication status:

fwauto auth status

Project Initialization

Enter your firmware project directory and run any fwauto command, such as fwauto build. FWAuto automatically starts a three-step setup wizard covering SDK, build, and deployment configuration.

SDK path [/opt/ti-sdk]:
[2/3] Build Configuration

  1. makefile
  2. command
Select [1]:
[3/3] Deploy Configuration
Deploy type:
  1. network
  2. serial
  3. command
Select [1]:

		

When setup is complete, FWAuto creates:

			
.fwauto/
├── config.toml      # Project configuration
├── build/
│   └── Makefile     # Build script (edit for your project)
└── logs/            # Log directory

		

Basic Usage

Build

fwauto build

If a build fails, the AI automatically attempts to repair it up to three times.

Deploy

			
fwauto deploy
fwauto deploy --binary-args "on"

Analyze logs

			
fwauto log "Are there any errors?"
fwauto log "Analyze this log" --log-path /path/to/uart.log

Help and Chat Mode

			
fwauto --help
fwauto
fwauto "Make the LED blink quickly"

Chat mode supports explicit Slash Commands such as /build and /deploy, as well as natural-language requests such as “build my firmware” or “deploy to the development board.”

Command	Function
/build	Build the firmware
/deploy	Deploy the firmware
/log	Analyze logs
/config	Manage configuration
/help	Show help
/exit	Exit chat mode

Troubleshooting

Authentication fails

			
fwauto auth logout
fwauto auth login

FWAuto cannot find .fwauto/

Run FWAuto from the project directory or one of its subdirectories. FWAuto searches parent directories for .fwauto/.

Update FWAuto

uv tool upgrade fwauto

After updating, run fwauto --help and verify the version shown below the banner.

Change the AI conversation language

/config set project.language zh-TW

Supported languages are en (English) and zh-TW (Traditional Chinese). Configuration errors, such as a missing Makefile, do not trigger AI repair. Confirm that the failure is a compilation error rather than a configuration error.

Appendix A: Windows Prerequisites

Install uv

			
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Install Node.js

Download the Windows Installer (.msi), version 20 or later, from Node.js Downloads. Use the default installation options and ensure “Add to PATH” is selected. Close and reopen PowerShell after installation. When required, run Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process again.

Appendix B: Makefile Requirements

When you select the makefile build type, FWAuto copies a template to .fwauto/build/Makefile. Modify it for your project.

Requirement	Description
Defined target	The default target is build and can be changed in config.toml.
Return code	Success = 0; failure = non-zero.
Output	stdout and stderr are captured for AI error analysis.

Variable	Purpose
ARAGO_ENV	SDK environment configuration path
SYSROOT	Cross-compilation sysroot
CC	Compiler
SRC_DIR	Source directory
BUILD_DIR	Output directory

Appendix C: Configuration Management

Use /config in chat mode to view the project configuration. Modify values with:

			
/config set <key> <value>
/config set project.language zh-TW

Appendix D: Arduino

			
[project]
name = "Blink"
[sdk]
path = "~/.arduino15"
[build]
type = "command"
command = "arduino-cli compile --fqbn arduino:avr:nano ."
[deploy]
type = "command"
command = "arduino-cli upload -p /dev/ttyUSB0 --fqbn arduino:avr:nano ."
[log]
type = "serial"
serial_port = "/dev/ttyUSB0"
baudrate = 9600

		

Appendix E: AM62X Development Board

			
[project]
name = "my-am62x-project"
[sdk]
path = "/home/alientek/ATK-AM62x-SDK"
[build]
type = "makefile"
makefile = ".fwauto/build/Makefile"
target = "build"
[deploy]
type = "network"
[deployment]
board_ip = "192.168.50.169"
board_user = "root"
deploy_path = "/home/root"
