avrdude -c micronucleus -p t85 -x wait -V -U flash:w:main.hex:i
```
### Support Teensy HalfKay bootloader
This build adds support for the [Teensy HalfKay bootloader](https://www.pjrc.com/teensy/halfkay_protocol.html), so you do no longer need a the Teensy Loader tool when working with Teensy devices.
Since this bootloader is optimized for size, it implements writing to flash memory only.
As it does not support reading, use the -V option to prevent AVRDUDE from verifing the flash memory. To have AVRDUDE wait for the device to be connected, use the extended option '-x wait'.
Supported devices are:
- Teensy 1.0 (AT90USB162)
- Teensy 2.0 (ATmega32U4)
- Teensy++ 1.0 (AT90USB646)
- Teensy++ 2.0 (AT90USB1286)
#### Example: Flashing a Teensy 2.0 device
```bash
avrdude -c teensy -p m32u4 -x wait -V -U flash:w:main.hex:i
```

// Notes:
// This file adds support for the HalfKay bootloader,
// so you do no longer need the Teensy loader utility.
//
// This HalfKay bootloader is used on various PJRC Teensy boards,
// such as Teensy 2.0 (ATmega32U4), Teensy++ 2.0 (AT90USB1286),
// and the respective clones.
// By default, it bootloader uses the VID/PID 16C0:0478 (VOTI).
//
// As the Teensy bootloader is optimized for size, it implements
// writing to flash memory only. Since it does not support reading,
// use the -V option to prevent avrdude from verifing the flash memory.
// To have avrdude wait for the device to be connected, use the
// extended option '-x wait'.
//
// Example:
// avrdude -c teensy -p m32u4 -x wait -V -U flash:w:main.hex:i
