3. Flash a .bin file
4. Reset the device into application mode (may be done automatically)
## AT32 DFU
All AT32 MCUs come preloaded with a factory bootloader that cannot be modified nor deleted.
To ensure compatibility with the AT32-DFU bootloader, make sure this block is present in your `rules.mk`:
```make
# Bootloader selection
BOOTLOADER = at32-dfu
```
Compatible flashers:
* [dfu-util](https://dfu-util.sourceforge.net/) / `:dfu-util` target in QMK (recommended command line)
```
dfu-util -a 0 -d 2E3C:DF11 -s 0x8000000:leave -D <filename>
```
Flashing sequence:
1. Enter the bootloader using any of the following methods:
* Tap the `QK_BOOT` keycode
* If a reset circuit is present, tap the `RESET` button on the PCB; some boards may also have a toggle switch that must be flipped
* Otherwise, you need to bridge `BOOT0` to VCC (via `BOOT0` button or jumper), short `RESET` to GND (via `RESET` button or jumper), and then let go of the `BOOT0` bridge
2. Wait for the OS to detect the device
3. Flash a .bin file
4. Reset the device into application mode (may be done automatically)
### `make` Targets
* `:dfu-util`: Waits until an AT32 bootloader device is available, and then flashes the firmware.
* `:dfu-util-split-left` and `:dfu-util-split-right`: Flashes the firmware as with `:dfu-util`, but also sets the handedness setting in EEPROM.
## tinyuf2
Keyboards may opt into supporting the tinyuf2 bootloader. This is currently only supported on F303/F401/F411.
