    Upload program using serial port (Teensy 3.2)

    Hello everyone!

    I have Teensy 3.2 and need to upload the program directly from the PC via the serial port (TX, RX). I do not want to use the USB port of Teensy. Now I try TTL for it, but it is not working. Can you please give me any suggestions?

    Thanks in advance and have a nice day.

    Yours sincerely,
    Sandip

    Sorry, programming by TTL level serial is not supported. USB is the only supported way.

    Thank you for your answer. Suppose my teensy is already programmed via USB and then I change some parameters in the program and I want to upload program in the same teensy without USB, then any other options are available or not?

    Thank you in advance.
