Heart beat missing after firmware upgrade.

G p y. + Expansion Board 2 , Upgraded firmware as per - https://docs.pycom.io/gettingstarted/installation/firmwaretool
Went without a hitch, runs ok, runs programs ok but no heartbeat. Did I miss something?

Hi @ckellow,

What code are you running on it? It is possible that you've turned it off with pycom.heartbeat(False). Can you test the LED to see if it works?
