Konnected cli-flash-tool

This is the tool we use to flash and pre-flight devices after manufacturing. It's a command-line (text-based) program written in Ruby that downloads firmware, flashes the device, and optionally generates and prints a label.

Prerequisites

This tool was written and tested on a Mac, but should work on Linux just as well. It may need some modification to run on Windows.

Ruby

Requires the ruby version specified. Recommended to use rbenv to manage Ruby versions.

brew install rbenv ruby-build       # Mac
# or
sudo apt install rbenv              # Debian/Ubuntu

rbenv init
rbenv install 3.2.2

esptool

Requires esptool to flash and communicate with the ESP.

brew install esptool                # Mac
pip install esptool                 # any system with Python

~/Downloads directory

The program will download firmware images to ~/Downloads. Make sure this directory exists!

Installation

Steps to install and set up this program.

Clone or download this repo:

Open a terminal window and navigate to your preferred workspace directory, then run:

git clone https://github.com/konnected-io/cli-flash-tool.git

  name: Brother_QL_810W
  ip: 192.168.1.33
serial_port_pattern: /dev/cu.usbserial*

flash

Set to true to flash the firmware, otherwise firmware will not be modified.

network_check

Set to true to run the Alarm Panel Pro network check.

label_printer

  • enabled - true to enable label printing
  • type - zpl if using a Zebra printer, otherwise pdf
  • name - The CUPS name of the printer (use lpstat -a)
  • ip - The IP address of the printer (only needed when using Zebra printers)

serial_port_pattern

A file path pattern to scan for devices connected via USB/UART ports.

Running

Run the program by executing it in Ruby:

bundle exec ruby cli_flash_tool.rb

Follow on-screen prompts to select the product and download the firmware image. Once the flash tool starts, plug in your device to a USB hub and it will start flashing automatically!
