# Setup for the selected toolchain
#
# Since all of the supported toolchains are variants of the Atmel-patched
# GCC, the only interesting question to answer here is whether or not
# the build is hosted on Windows, and how to override the configuration.
#
# NOTE: There is a logic error in the following: CONFIG_HOST_WINDOWS means
# that we are operating on a Windows platform. But in the case where we
# have an AVR32 toolchain built under Cygwin, the correct setting would be
# GNU, not AVRTOOLSW.
#
CROSSDEV = avr32-
ARCHCPUFLAGS = -mpart=uc3b0256
ifeq ($(filter y, \
$(CONFIG_AVR32_AVRTOOLSW) \
$(CONFIG_HOST_WINDOWS) \
),y)
# AVR Tools under Windows
CONFIG_AVR32_TOOLCHAIN ?= AVRTOOLSW
else
CONFIG_AVR32_TOOLCHAIN ?= GNU
endif
ifeq ($(CONFIG_AVR32_TOOLCHAIN),AVRTOOLSW)
ifneq ($(CONFIG_WINDOWS_NATIVE),y)
WINTOOL = y
endif
else
# AVR Tools or avr32-toolchain from https://github.com/jsnyder/avr32-toolchain
