# Makefile for MicroPython on ESP32.

# This is a simple, convenience wrapper around idf.py (which uses cmake).
# Select the board to build for:
ifdef BOARD_DIR
# Custom board path - remove trailing slash and get the final component of
# the path as the board name.
BOARD ?= $(notdir $(BOARD_DIR:/=))
else
# If not given on the command line, then default to GENERIC.
BOARD ?= GENERIC
BOARD_DIR ?= boards/$(BOARD)
endif
ifeq ($(wildcard $(BOARD_DIR)/.),)
$(error Invalid BOARD specified: $(BOARD_DIR))
endif
# If the build directory is not given, make it reflect the board name.
BUILD ?= build-$(BOARD)
# Device serial settings.
PORT ?= /dev/ttyUSB0
BAUD ?= 460800
PYTHON ?= python3
# Would be good to use cmake to discover submodules (see how rp2/Makefile does
# it), but on ESP32 the same trick doesn't work because "idf.py build" fails
# on berkeley-db dependency before printing out the submodule list.
# For now just force the submodule dependencies here.
