When I try to write the following micropython code to flash to run at start-up, I get the error below. Then what appears to be a reset.
Applying the same code via paste mode gets the expected results: the LED flashes.

>>>
flash compile mode; Ctrl-C to cancel, Ctrl-D to finish
1^^^ from machine import Pin
2^^^ import time
3^^^ dio5 = Pin(“D5”, Pin.OUT, value=0)
4^^^ while True:
5^^^ time.sleep(1)
6^^^ dio5.toggle() # Flash the LED on DIO5 (D5)

OSError: [Errno 7019] ENODEV

MicroPython v1.10-1179-g94f4f29 on 2019-04-03; XBee3 DigiMesh 2.4 with EFR32MG
Type “help()” for more information.

It looks to me like the compilation is failing, but I can’t find much info on this error aside from it meaning “No such device”.
Any help would appreciated, thanks.

You need to format your file system. In command mode issue a: atfs format confirm.

You are welcome

Or from MicroPython, “os.format()” (after “import os”).
