Sonix Flasher

Usage

Entering bootloader

You must boot into bootloader to flash the firmware，you have some choices to do it

• for stock firmware，click “Reboot to Bootloader” if your keyboard listed in the device list
• Pulled down the BOOT pin
• If you have a jumploader ，It’s strongly recommended to flash the jumploader on SN32F260 since the 260 series can become brick if the bootloader is overrided. See

Flash Firmware

• Set qmk_offset to 0x200 only if you have a jumploader flashed in the keyboard

Compile

python3 -m venv venv
. venv/bin/activate
pip install wheel
pip install -r requirements.txt
fbs run
# or "fbs freeze" to create the package

Alternatively, if you're running NixOS or have Nix installed, you can run

nix shell
fbs run

To run it for immediate use, just run run.sh and it'll set itself up and run.

UDEV

Run with sudo to flash unless you have the correct udev rules set up.

To setup the udev rule, run this command (tested for Berseker).

sudo bash -c 'cat << EOF > /etc/udev/rules.d/52-flash-keyboard.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0c45", ATTRS{idProduct}=="7040", GROUP="users", MODE="0666"
EOF'
sudo systemctl restart udev

In order to check your bootloader's vendor & product IDs, run the following command, then immediately put your keyboard in bootloader mode, and wait for the diff.

lsusb > /tmp/pre; sleep 30; lsusb > /tmp/post; diff -u /tmp/pre /tmp/post

You should get something like this, look at the line starting with +.
