##### 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
|
|
##
