ZMK-Flasher

A small go cli application to simplify flashing ZMK firmware to ZMK powered split keyboards. It helps by letting you specify the firmware files of the right and left half by their single files or as a zip and mounting the keyboard bootloaders interactively. Afterwards it will copy the firmware to the keyboard halves. Currently Linux and MacOS are supported.

Installation

To install zmk-flasher run

go install github.com/new-er/zmk-flasher@latest

Usage

To flash a firmware run the following command:

zmk-flasher flash -l left_firmware.u2f -r right_firmware.u2f

This lets you mount the left and right keyboard halves interactively. Afterwards the application will flash the firmware to the left and right halves.

You can also flash a single firmware file to both halves (Glove 80):

zmk-flasher flash -a firmware.u2f

Or you can directly use a zip file as long as there are two files in it, one containing left and the other right in the file name.

zmk-flasher flash -z firmware.zip

To find more about the usage of the application, run the following command:
