- Press the programming button (marked red). The small LED on the Teensy lights up red — it is now in programming mode.
- Select the firmware you want to flash (v3.0 or Beta).
- Press Select Teensy Device, choose Teensy in the list (it may show as “Unknown device”), then press Connect.
- Press Upload Firmware. The Teensy LED flashes brighter a few times.
- After a successful flash, TŒRN reboots automatically.
