Firmware Update Guide (Linux CLI)-EN

Preparation

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

For example in Ubuntu, run:

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

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

You can use the same environment for future firmware updates.

Download and unpack the firmware archive.
Open a terminal and activate the update workspace you created earlier (e.g. gyrfalcon_update):
. gyrfalcon_update/bin/activate
Adjust the path as necessary.
Plug in the power supply to the charger, then connect the charger via USB to your computer.
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

Set up the serial connection:

stty -F /dev/ttyUSB0 115200 cs8 -cstopb -parenb

Reboot the charger into the bootloader by executing:
echo '*fwupdrst' > /dev/ttyUSB0
Now you are ready to upload the firmware. Adjust the path as required:
ymodem send -p /dev/ttyUSB0 /path/to/GYRFALCON_S8000_Firmware.bin
After a successful update, the charger will reboot automatically.
