Firmware Update Guide (Linux CLI)-EN

Preparation

Install dependencies

Following packages are required and must be installed before performing the update.

• • Python 3
  • python-pip
  • python-venv

For example in Ubuntu, run:

sudo apt update
sudo apt install python3 python3-pip python3-venv

Create workspace for update

This creates a virtual Python environment and downloads required modules.
Open a terminal and run:

mkdir gyrfalcon_update
cd gyrfalcon_update
python3 -m venv .
. bin/activate
python3 -m pip install ymodem

Perform the update

1. Download and unpack the firmware archive.
2. Open a terminal and activate the update workspace you created earlier (e.g. gyrfalcon_update):
   
   . gyrfalcon_update/bin/activate

   Adjust the path as necessary.

3. Plug in the power supply to the charger, then connect the charger via USB to your computer.
4. A new serial device should appear, most likely /dev/ttyUSB0.
   Use this device in all further commands.
   It might be necessary to give your user additional permissions:
   sudo chmod 666 /dev/ttyUSB0
5. Set up the serial connection:
   
   stty -F /dev/ttyUSB0 115200 cs8 -cstopb -parenb
6. Reboot the charger into the bootloader by executing:
   
   echo '*fwupdrst' > /dev/ttyUSB0
7. Now you are ready to upload the firmware. Adjust the path as required:
   
   ymodem send -p /dev/ttyUSB0 /path/to/GYRFALCON_S8000_Firmware.bin
8. After a successful update, the charger will reboot automatically.
