Thread: Teensy 4.1 Auto Recovery

    Teensy 4.1 Auto Recovery

    I've had Teensy 4.0 since it was introduced, recently got a 4.1. I never got around to trying the Automatic Recovery feature.

    I've tried it a few times, and haven't gotten it to start running Blink.

    I hold the button for 17 seconds, then release. How long should it take to reinitialize and start Blink'ing?

    Hold the button until you see the one led just blink and then release it, It should then show that LED lit up for awhile as it reprograms it, and then you should get the blink (the other LED) program on it running.

    Thanks for your reply.

    Approximately how long should it take after releasing the button?

    Edit: I've got it now. It wasn't working with the 10000mah USB battery is was using.

    Solid red light remains for about 45 seconds which reiitializing the flash, the the orange LED starts Blinking.

    My guess is somewhere between 30-45 seconds. I did not time it
