Can do do an "Erase All" operation? https://forum.pycom.io/topic/5318/flashing-v1-20-r1-bricks-my-lopy4

@crumble Not a bad work around! Thanks for your help.

@Innocenzo The latter is easy, I have that in all of my espxxx's main.py: wlan = network.WLAN(network.STA) for _ in range(10): if wlan.isconnected(): print('\nnetwork config:', wlan.ifconfig()) break print('.', end='') time.sleep(1) else: print("\nCould not connect")
