"particle flash -- serial" usually fails on Electron

Troubleshooting

What is the code used for doing the Serial() stuff?

22

Iā€™m not sure I understand the question. Do you mean what am I using Serial for, or what code am I using?

At the moment Iā€™m just outputting some Serial data for debugging as I go. I do a ā€œSerial.begin(9600);ā€ in setup() and then I print the time in loop()ā€¦

hr = Time.hour();
min = Time.minute();

Serial.print("Time: ");
Serial.print(hr);
Serial.print(":");
Serial.println(min);

After fixing the serial assignments in my laptop device manager it looks like that problem is fixed as well.

Make sure your user firmware version matches the system firmware version thatā€™s on the device. It shouldnā€™t ever hurt to particle update to get the latter up to date.

Help me out here. Youā€™re saying the firmware on my Electron should be updated - right? But this must not be the firmware that I write and load. I assume this is the lower level stuff like the bootloader?

And what is my ā€œuser firmware versionā€?

Sorry for the dumb questions.

I think Iā€™ve got the firmware version sorted out. I just did a ā€œparticle updateā€ and updated the firmware target - both to 0.6.1.

Thanks.
