revised_makefile.mk

# ** Readme! **
# Don't edit this file! This is the core Makefile for a MaximSDK 
# project. The available configuration options can be overridden 
# in "project.mk", on the command-line, or with system environment 
# variables.

# See https://github.com/Analog-Devices-MSDK/VSCode-Maxim/tree/develop#build-configuration 
# for more detailed instructions on how to use this system.

# The detailed instructions mentioned above are easier to read than 
# this file, but the comments found in this file also outline the 
# available configuration variables. This file is organized into 
# sub-sections, some of which expose config variables.

# Set the target microcontroller and board to compile for.  

# Every TARGET microcontroller has some Board Support Packages (BSPs) that are 
# available for it under the MaximSDK/Libraries/Boards/TARGET folder. The BSP 
# that gets selected is MaximSDK/Libraries/Boards/TARGET/BOARD.

# Configuration Variables:
# - TARGET : Override the default target microcontroller.  Ex: TARGET=MAX78000
# - BOARD : Override the default BSP (case sensitive).     Ex: BOARD=EvKit_V1, BOARD=FTHR_RevA

# should point to the root directory of the MaximSDK installation.  Setting this manually
# is usually only required if you're working on the command-line.

# If MAXIM_PATH is not specified, we assume the project still lives inside of the MaximSDK 
# and move up from this project's original location.

# - MAXIM_PATH : Tell this Makefile where to find the MaximSDK.  Ex:  MAXIM_PATH=C:/MaximSDK

# - VPATH : Tell this Makefile to search additional locations for source (.c) files.
# 			You should use the "+=" operator with this option.  
#			Ex:  VPATH += your/new/path
# - IPATH : Tell this Makefile to search additional locations for header (.h) files.
# 			You should use the "+=" operator with this option.

# 			This is really only useful if you want to add a source file that isn't
#			on any VPATH, in which case you can add the full path to the file here.

# Secure Boot Tools (SBT)
# This section integrates the Secure Boot Tools.  It's intended for use with
# microcontrollers that have a secure bootloader.
# Enabling SBT integration will add some special rules, such as "make sla", "make scpa", etc.
# Configuration variables:
#	SBT : 	Toggle SBT integration.  Set to 1 to enable, or 0
# 			to disable
#	MAXIM_SBT_DIR : Specify the location of the SBT tool binaries.  This defaults to
#					Tools/SBT in the MaximSDK.  The standalone SBT installer will override
#					this via an environment variable.
#	TARGET_SEC : 	Specify the part number to be passed into the SBT.  This should match
#					the secure variant part #.  The default value will depend on TARGET.
#					For example, TARGET=MAX32650 will result in TARGET_SEC=MAX32651, and
#					the default selection happens in Tools/SBT/SBT-config.
#					However, if there are multiple secure part #s for the target
#					microcontroller this variable may need to be changed.
