## tinyuf2
|
||||
|
||||
Keyboards may opt into supporting the tinyuf2 bootloader. This is currently only supported on the F411 blackpill.
|
||||
|
||||
The `rules.mk` setting for this bootloader is `tinyuf2`, and can be specified at the keymap or user level.
|
||||
|
||||
To ensure compatibility with the tinyuf2 bootloader, make sure this block is present in your `rules.mk`:
|
||||
|
||||
```make
|
||||
# Bootloader selection
|
||||
BOOTLOADER = tinyuf2
|
||||
```
|
||||
|
||||
Compatible flashers:
|
||||
|
||||
* Any application able to copy a file from one place to another, such as _macOS Finder_ or _Windows Explorer_.
|
||||
|
||||
Flashing sequence:
|
||||
|
||||
1. Enter the bootloader using any of the following methods:
|
||||
* Tap the `RESET` keycode
|
||||
* Double-tap the `nRST` button on the PCB.
|
||||
2. Wait for the OS to detect the device
|
||||
3. Copy the .uf2 file to the new USB disk
|
||||
4. Wait for the keyboard to become available

To trigger keypress, short together pins *B0* and *A7*.
|

This variant requires the TinyUF2 bootloader to be installed. This can be downloaded from the [tinyuf2 releases page](https://github.com/adafruit/tinyuf2/releases). The F401 blackpill binary works for both F401- and F411-based blackpill devices.
|
