#-------------------------------------------------------------------------------

# This makefile does not contain any targets, only definitions used by the

# makefiles of all the code samples.

# It is meant to be included and not used standalone.

#-------------------------------------------------------------------------------

# SYSTEM PARAMETERS

#

# You can define here the default size and address of the memory blocks of the

# system as seen by the linker, though you can't change the number and type of

# blocks here (see /vhdl/mips_cache_*.vhdl and /vhdl/mips_pkg.vhdl).

#

# The samples' makefiles will probably redefine the values, anyway.

#

#-------------------------------------------------------------------------------

# NOTE:

# A link script '/src/ion_noxram.lds' was used in previous versions of the

# project. It is no longer used. It is known to be buggy and will be removed.

#

# See info on flag -G0 in ion_noxram.lds

### Default system parameters -- to be replaced in application makefile ########

# 'CODE_BRAM' is meant to be a small BRAM (2 to 4KB) used for bootstrapping.

# 'DATA_BRAM' is a small BRAM connected to the data ports, used for debugging.

# 'XRAM' is meant to be the main external RAM, either SRAM or SDRAM.

# Default location of code BRAM is on the reset vector address

CODE_BRAM_ADDRESS = 0

# Default size of code BRAM in 32-bit words

CODE_BRAM_SIZE = 1024

# Default size of data BRAM in 32-bit words (meant for simulation only)

DATA_BRAM_SIZE = 256

# Default address of BRAM -- used in some simulation-only tests, see makefiles

# Default size of data external RAM (XRAM) in 32-bit words (for simulation)

### Project directories -- to be replaced in application makefile ##############

# Root test code source directory, where python script and vhdl templates are

SRC_DIR = ..

# VHDL test bench directory, where VHDL output files will be created

TB_DIR = ../../vhdl/tb

# VHDL DE-1 board demo root directory, for vhdl output

# Path to local libraries

LIB_PATH = $(SRC_DIR)/common/libsoc

# Link script to be used

LINK_SCRIPT = $(SRC_DIR)/common/flash.lds

### Build options -- to be replaced in application makefile ####################

# Don't use gcc builtin functions, and try to target MIPS-I architecture

# This will prevent usage of unimplemented opcodes but will insert nops after

# load instructions, which Ion does not need.

# (See comment above about -G0 flag)

CFLAGS = -O2 -Wall -c -s -fno-builtin -mips1 -G0 -nodefaultlibs -nostdlib

# LFLAGS: linker options are in the respective makefiles
