# How to compile NIOS code and produce Altera flash files

# Start a nios command line shell:
cd $HOME/altera/13.1/nios2eds/nios2_command_shell.sh

# Prepare and make the board support package:
cd $PROJECT/software/dtb_bsp/
nios2-bsp-generate-files --settings=settings.bsp --bsp-dir=.
make

# Build the software package:
cd ../dtb_expert/
make

# Create the flash file:
cd ../../FLASH/
./makeimg.sh

# This script contains the following calls:
#!/bin/sh
export QUARTUS_BINDIR=${QUARTUS_ROOTDIR}/bin
