My particle Electron board was sealed up inside the box that came with the solar kit and it WAS working. Today I decided to try to write some code for it and I was not able to upload the code. I could see inside the box that the RGB led was not lit up, but the blue D7 led was on solid. I took it out…

So if an Electron has no lights except the Dim Blue D7 there is no way to get it out of this state? Anything I can do with it ?

Hi @GavinS It sounds like your Electron is in the “no firmware” state. It can be recovered with a JTAG programmer for sure, but you will need help. I would contact Particle support and ask for help with this.

A possible shot, if you have no JTAG programmer or Particle Programmer Shield, might be this already mentioned methode [image] m-mcgowan/embedded-swd embedded-swd - Serial Wire Debug (SWD) implementation for Particle devices As long you have one good Particle de…

Yeah, I tried that Norwegian Blue (SWD) thing. The lights come on, but it just sits there. I left it “fixing” it for days. I’d love to know how to use the JTAG debugger on this. I may need to make a new cable. I have a Tin Can Tools Flyswatter 2, but it doesn’t have open pins, just a JTAG cable…

I haven’t tested this yet … but I was measuring the voltage of the external battery with an external voltage sensor on B4. If I detect the external voltage has gone below … say … 11.0V … and I call PMIC.disableCharging() … I’m hoping that’s enough to keep me from replicating the “DIM Blue D7” situa…

Hello, any updates on this? I have experienced the same issue with my electron, dim blue D7 light. I am trying to go through the SWD Norwegian Blue but can’t seem to get the programmer app to work in the serial terminal after flashing to photon. I am using a working photon to remedy my electron. Aft…

My apologies, it works when I open the terminal with Coolterm. However, I get the same fault as @jasonp . I’m open to suggestions. Thanks

Hi all. Sadly we have now experienced this as well :frowning: Even worse, it happened while we were demoing our product overseas :frowning: However, the reason I really wanted to post is that we may be able to add an important bit of information: Our battery was charged. It was probably around …

I have also killed an Electron by allowing the battery to go completely flat and having no RGB LED activity. I connected up the programmer device (Photon) to the Target device (Electron). However, when I tried the Norwegian Blue program, I got no activity in my serial monitor. I only got the steady…

Electron stopped working?
