 ### I just flashed my keyboard and it does nothing/keypresses don't register - it's also ARM (rev6 planck, clueboard 60, hs60v2, etc...) (Feb 2019)
 Due to how EEPROM works on ARM based chips, saved settings may no longer be valid.  This affects the default layers, and *may*, under certain circumstances we are still figuring out, make the keyboard unusable.  Resetting the EEPROM will correct this.
