I’m having some trouble with a redbear duo that seemed to work fine, at least until about 2 weeks ago.
Now, it isn’t recognized by either of the computers I have successfully programmed it with in the past, and it’s LED colour patterns don’t seem to match what’s supposed to happen. For example, if I press SETUP and RESET and then let go of RESET, here is the pattern of lights I see:
- about 8 red blinks
- about 16 yellow blinks (if I let go here, it will keep flashing yellow, but is not recognized as a DFU device)
- a bunch of really fast green flashes
- a bunch of really fast yellow flashes
- steady yellow for a second
-off for a second
-really fast yellow flashes
-steady yellow for a second
Does anyone know what that pattern of lights means? It’s not the patterns described in https://docs.particle.io/tutorials/device-os/led/photon/ as far as I can tell. But it is clearly a pattern.
I have installed dfu-util before and used it, but it doesn’t see it as a DFU device when it’s blinking yellow and I can’t burn the bootloader.
My computer can recognise other redbear duos.
I may try to burn the bootloader with a programmer connected to the ICSP pins.
