Hi,
i wrote a "Bootloader" which reads a HEX-File from a SD-Card and writes it's contents to the flash-memory of the Teensy 3.1 / 3.2.
The maximum binary size is 128KB (this is NOT the size of the "*.hex"-file)
It is not very well tested, so be careful.
Don't press the button while flashing, and don't disconnect the power - a bricked Teensy will be the result.
Again, be careful.
There is no chance to rescue a bricked Teensy - don't ask the forum - really, there is no chance. Buy a new one. I can not help you, Paul can not help you.
Be careful
The usage is easy, please try the included example, with "blink.hex"

Have fun,
Frank.
