teensy4-selfrebootor

This crate provides a USB device compatible with teensy_loader_cli -r to force the Teensy4 to reboot itself into bootloader.

This allows the board to be reprogrammed without having to press the Reset/Boot button.

A requirement of this crate is that there is no other use for the USB port, as it will fully consume it.

Examples

- examples are intended for the Teensy 4.0, Teensy 4.1 or Teensy MicroMod board -

Prerequisites

The following hardware is required for the examples:

• A Teensy 4.0/Teensy 4.1/Teensy MicroMod development board

The following software tools have to be installed:

• Python3 (as python3, or modify run.py to use the python binary)
• cargo-binutils
• teensy_loader_cli

Run

• Connect the Teensy to PC via USB cable.
• Press the Reset/Boot button on the Teensy.
• Run:

• Run the previous command again. This time the command should not need the Reset/Boot button. The Teensy should switch to boot mode automatically.
