Preparation Before System Burning

1. Prepare the required equipment

If using a TF card to boot the system, the following equipment is needed

• Card reader
• A TF card, capacity 16GB-128GB, with a transfer speed of class10 or higher.
• It is recommended to use TF cards from well-known brands such as SanDisk, Samsung, and Kioxia. Do not use counterfeit TF cards!
• Windows system computer (Windows 7, Windows 10, Windows 11 are all acceptable)

If using M2WE to boot the system, the following equipment is needed

• M2WE (FLY proprietary device)
• M2SD (FLY burning device)
• Windows system computer (Windows 7, Windows 10, Windows 11 are all acceptable)
• Installation diagram
  

2. Download the FLY-H5 system image:

   • The current FAST version is FlyOS-FAST-
   • Please note that you need to download the FLY-H5 image in the FlyOS-FAST- folder
   • Click the download link below
   • Loading...
     tip

     • System file naming rule: FlyOS-Fast-[chip series]-[version number].img, for example: FlyOS-Fast-H5-v1.0.0.img
     • For Windows system, download the .exe file, which is a 7z self-extracting compressed package. After downloading, double-click to open and extract, then you can get the .img file (only Windows system can extract)
     • For other systems such as macOS and Linux, download the .7z file, which is a 7z compressed package. After downloading, use a tool that supports 7z format to extract and get the .img file
     • Due to the large size of the system file, other compression formats and source image downloads are temporarily not provided
     • This tutorial uses the .exe and GOOGLE drive as examples
   • Access the cloud disk, click FlyOS-FAST-
   
   • Click the image you need to download
   • This tutorial needs to download Fly_FAST-H5.exe
   
   • Click still download
   

3. Extract the system image file to get the .img file.

   • Double-click or right-click to open FlyOS-Fast-H5.exe, wait a few seconds, and a window will pop up (if the system prompts it is not safe, select "More information" -> "Run")
   • You can choose the extraction directory, then click the Extract button, and wait for the extraction to complete.
   
   • After extraction, a FlyOS-Fast-H5-vx.x.x.img file will be generated in the extraction directory. x.x.x is the system version number.

• The FLY host machine requires either the M2WE or 2.4G WIFI module to use WiFi
• Please note that the host machine does not support WiFis with Chinese names and does not support dual-band (2.4G and 5G) unification

• The red arrow points to the Wi-Fi antenna interface
• The Wi-Fi antenna port is ipex1
• Please install the antenna on the M2WE, otherwise poor signal may cause connection failure to the router

tip

• After completing the system card installation, you can proceed to the next step by connecting to the host machine via SSH

2. Power on the host machine.
   Your host machine is now ready to start up!!!
