## Bootloader
|
|
|
|
Enter the bootloader in 3 ways:
|
|
|
|
* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
|
|
* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
|
|
* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
|
|
|
|
The rev 2 uses pin `A10` in the key matrix, which apparently is a design flaw that may prevent the bootloader from entering the proper mode for DFU flashing - <https://docs.qmk.fm/#/platformdev_blackpill_f4x1?id=pins-to-be-avoided>. There is a simple workaround that works most of the time - press the pin key (generally the letter R) during the boot.
