##### COMMENTS ABOUT LINKLABS HACKS still yet to be done
##
## Resin folks (Andrei, on 4/22) are working on some changes
## that will ultimately enable TWO ways of dealing with RPI3:
##
## Option #1: Leave RPi serial on /dev/ttyS0 and bluetooth on /dev/ttyAMA0
## This would require adding this Fleet Configuration variable, which
## fixes RPi3 serial port speed issues:
## RESIN_HOST_CONFIG_core_freq = 250
## This option also requires us to change the run.sh
## so that when GW_TYPE==linklabs-dev we default the
## serial port to /dev/ttyS0 rather than /dev/ttyAMA0
##
## Option #2: Disable bluetooth and put RPi serial back onto /dev/ttyAMA0
## This would require adding this Fleet Configuration variable:
## RESIN_HOST_CONFIG_dtoverlay=pi3-miniuart-bt
##

##### Raspberry Pi 3 hacks necessary for LinkLabs boards
##
## Because of backward incompatibility between RPi2 and RPi3,
## a hack is necessary to get serial working so that we can
## access the GPS on the LinkLabs board.
##
## Option #1: Leave RPi serial on /dev/ttyS0 and bluetooth on /dev/ttyAMA0
## This requires adding this Fleet Configuration variable, which
## fixes RPi3 serial port speed issues:
## RESIN_HOST_CONFIG_core_freq = 250
##
## Option #2: Disable bluetooth and put RPi serial back onto /dev/ttyAMA0
## This requires adding this Fleet Configuration variable, which
## swaps the bluetooth and serial uarts:
## RESIN_HOST_CONFIG_dtoverlay=pi3-miniuart-bt
