Locally compiled and flashed code ends up in safe Mode. Why?

Getting Started
1

I've run the online examples for my electron and now (being old school) want to compile and flash files locally on my Mac via USB.

I'm sure this is a rookie error, but, in short, it's always going into Safe Mode after I flash the code. What am I missing?

Details:

Here my blinko.ino file in its entirety:

#define PIN D7
int state = 0;

void setup() {
    pinMode(PIN, OUTPUT);
}
void loop() {
    digitalWrite(PIN, (state) ? HIGH : LOW);
    state = !state;
    delay(500);
}

Workflow

After installing node, particle and dfu on my Mac, I did the following:

Compile

$ particle compile e ./blinko.ino

Compile succeeded.

Flashing

I put the electron into DFU mode, and then:

$ particle flash --usb e_firmware_1500951434587.bin

... and then...

The Electron goes through the following sequence:

  1. Flash Green (fast)
  2. Flash Cyan (really fast)
  3. Breathe Magenta (Safe Mode)

Not sure, but maybe your device wasn’t already updated to 0.6.2 system.
For Electrons this would just cause Safe Mode to tell you to upgrade first - Photons would perform an auto-upgrade.

BTW, particle compile also builds in the cloud
