Which Teensy model or method supporting to upload program except USB?

[Sandip]

Hello!

I have programmed a Teensy 3.2 and I change some parameters in the program and I want to upload again via serial port (TX, RX) without USB. If this is not possible, please suggest me the other Teensy model that allows uploading program via the serial port or any other method except USB.

Thanks in advance.

I'm pretty sure that the answer PaulStoffregen gave you on your previous question applies to all Teensy's.

No Teensy model supports this. USB is the only supported upload method on all Teensy boards.

Please do not create duplicate threads to re-ask the same question.

I change some parameters in the program

In case you only need to change some parameters you do not need to upload a new program. You can do this via Serial and have your sketch store the parameters in the EEPROM. Your sketch can then use those values.
