# This is an example makefile for SparkFun Apollo3 boards as used in the
|
||||
# AmbiqSuite SDK.
|

#
|
||||
# Recommended usage
|
||||
# make
|
||||
# make bootload_svl (uses the SparkFun Variable Loader to upload code)
|
||||
# make bootload_asb (uses the Ambiq Secure Bootlaoder to upload code)
|

# make clean

||||
#
|

# Filepaths
|
||||
# You can relocate this makefile easily by providing the path to the root of
|
||||
# the AmbiqSuite SDK. If that path is not specified then this file will
|
||||
# assume that it is located in
|
||||
# <AmbiqSDKRoot>/boards/<your_board>/examples/<your_example>/gcc
|
||||
# and use relative paths
|
||||
#
|
||||
# User Configuration
|
||||
# You must also specify which COM_PORT to use if you want to use the
|
||||
# 'bootlaoder' targets.
|
||||
# Windows example: COM_PORT=COM4
|
||||
# *nix example: COM_PORT=/dev/usbserialxxxx
|
||||
#
|
||||
# Python vs. Executable
|
||||
# For simplicity the upload tools are called as Python scripts by default.
|
||||
# Make sure PYTHON is set to the appropriate command to run Python3 from the
|
||||
# command line.
