Pro trinket 3v no red led

by baramuse on Thu Jun 06, 2019 6:36 pm

Hi all,

I've been trying to "reuse" a trinket pro I had played with before, but can't seem to get anything out of it.

When I plug it into my macbook pro, only the green LED lights up (and stay still), no red LED, no blinking, nothing when RESET pressed.
I tried different USB cables(although I'm programming other boards with so I know they work).
I got a working M0, itsybitsy, nRF52,... so the IED and cables (and my brain) should be ok.

I tried connecting to a usb2.0 hub as well.. nothing.

Any Help ?

What happens when you press the reset button? Any LED activity?

nothing happens when RESET pressed. No led activity/changes, still still green light, no red light.

Sounds like the bootloader is not running. You may be able to revive it by re-burning the bootloader:
