# Corne v4.1

My keyboard settings. Mostly inspired by [Miryoku](https://github.com/manna-harbour/miryoku) and [this](https://habr.com/ru/articles/717912/) Russian keyboard layout.

# Flashing

https://www.ergokeeb.com/blogs/news/guide-to-flash-vial-firmware-on-the-corne-v4-1-wired-keyboard

- `git clone https://github.com/vial-kb/vial-qmk`
- Move your files to the `~/vial-qmk/keyboards/crkbd/keymaps/vial/` directory. Or you can create your own directory in `keymaps` instead of `vial` and put your files there.
- `qmk compile -kb crkbd/rev4_1/standard -km vial`

## **Step 1: Enter Bootloader Mode**

For the Corne V4.1, entering bootloader mode is straightforward due to its RP2040-based design (or similar), which mounts as a USB drive when in bootloader mode.

**Method 1:** You can either press the reset button or hold down the "Q" or "P" keys while plugging in the keyboard to enter the bootloader and flash the new firmware.

**Method 2:** Connect to the PC while holding down the **BOOT** button, or while connected to the PC, hold down the **BOOT** button and press the **RESET** button. After that, an RPI-PR2 device will be mounted.

## **Step 2: Flash the Firmware**

1. **Flash the Left Half:**
    - Open the RPI-RP2 drive.
    - Drag (or copy and paste) the firmware file into the drive.
    - Wait a few seconds—the drive will disappear once flashing is complete.
2. **Flash the Right Half:**
    - Disconnect the left half.
    - Repeat **Step 2** for the right half, then drag the firmware file into the RPI-RP2 drive.
    - Wait for the drive to vanish, confirming the flash.

## **Step 3: Test the Keyboard**

1. **Connect the Halves:**
    - Use a TRS cable to connect the left and right halves.
    - Plug the left half into your computer via USB (for wired setups, the left half is typically the “master”).
2. **Verify Functionality:**
    - Open the Vial application (or a text editor like Notepad).
    - Press keys on both halves to ensure they register correctly.
    - If the keyboard isn’t detected or keys don’t work, double-check the firmware files match your hardware and that the TRS connection is secure.
3. **Use Vial:**
    - In the Vial app, your Corne V4.1 should appear if the firmware was flashed correctly. You can now customize keymaps, layers, and settings without reflashing.
