Pro trinket - broken?

Post by alwayssunny »

Hi,
I made a mistake when uploading a program to pto trinket 5V.
I did an upload when in IDE 3v Pro Trinket was selected.
Now the computer does not recognize the trinket.
Can I fix it?

That should not have damaged anything. Have you tried to move the Trinket to a different USB port and push the reset button on it?

Yes I have, I deleted the driver and installed again, and still the 3v is recognized and the 5v is recognized as Unknown Device.
I rebooted the computer, tried another Arduino IDE, all the same.

You may have a corrupted bootloder.

The source code for the Pro Trinket bootloader is here: https://github.com/adafruit/Adafruit_Pr ... Bootloader and you can try reprogramming the ATmega328 with that.
