# Flashing Guide

## Blue-pill Based:

This includes the Practice60, Ortho60, and Ortho48

Note

At the moment, QMK Toolbox does not support Blue-pill based boards. Work is being done to make the flashing process easier. In the meantime, this is the easiest way to flash.

1. Before flashing, you must have a .bin file with your firmware. For more information on how to get the proper firmware, visit the firmware guide. You will also need a second keyboard for the time being.
2. To flash a blue pill based board, you will need dfu-util. Download it following the directions on the dfu-util site.
3. If you're on Windows you'll also have to download this zip and run install_drivers.bat. Windows actually comes with the proper drivers, they're just not properly associated with the Blue Pill's USB ID, so this will do that.
4. dfu-util is a command line tool, so we will have to open a command line to run it. On Windows, open Command Prompt. On Mac OS X, open Terminal. If you're using linux, you probably already know how to open a terminal!
5. Navigate to the directory you have dfu-util installed using cd to change directories and dir (Windows) or ls (Linux) to list files.

Example

If your dfu-util was installed in Downloads, open command prompt and run cd Downloads to get to the correct folder. Verify you're in the right place by using dir. Make sure dfu-util.exe shows up in the dir output!

6. Put your keyboard into flashing mode. You can do this by hitting the reset button on the keyboard, or by using the RESET key, if it's been mapped. At this point, the keyboard you are flashing will no longer work as a keyboard, so you'll have to use a 2nd keyboard for the next steps.

7. Figure out the path to your firmware. In Windows Explorer, you can do this by navigating to your firmware, and following the instructions on this page to copy the file path.
8. Run dfu-util.exe -d 1eaf:0003 -a 2 -D "\path\to\firmware.bin", replacing \path\to\firmware.bin with the path you found on the last step.
9. Congrats! You should see File downloaded successfully and you have flashed new firmware onto your keyboard! Either unplug and re-plug your board, or hit the hardware reset button to exit flashing mode.

Note

On some systems after the flashing finishes, you'll see Error sending completion packet, as well as 97% completion. This can be safely ignored!

## Reflashing the bootloader on a Blue-pill

### Mac OS

#### Requirements

To reflash your bootloader on Mac OS, you first need st-flash and possibly openocd to unlock your blue pill, in addition to your ST-Link. st-flash (via stlink) and openocd can be installed from Homebrew.

brew install openocd stlink


The first thing you'll need to do is hook your ST Link into your Blue-pill. For some reason, on Mac OS, you may need to swap the SWDIO and SWCLK pins. Additionally, you may need to update your ST-Link's firmware with STSW-LINK007. You'll also need the bootloader binary

1. Ensure that your Blue-pill is recognized by running st-info --probe
• if the chipid is 0x0000, swap the SWDIO and SWCLK pins
• if the chipid is 0x0410, you're connected correctly
2. Attempt to flash the bootloader using st-flash --reset --format binary write path/to/generic_boot20_pc13.bin 0x8000000
• if you get a Unknown memory region error message, you'll need to unlock the chip with the following command then unplug your ST Link to reboot the Blue-pill:
openocd -f interface/stlink-v2.cfg \
-f target/stm32f1x.cfg \
-c "init; reset halt; stm32f1x unlock 0; reset halt; exit"


If you see the following (or something similar), your Blue-pill was successfully flashed

st-flash 1.5.1
