Makefile Tricks

Automatic Download

This automatically downloads your program to the Spartan board after building. It assumes $(NAME).elf is the file you'd like to download. Note that you will probably miss warning messages regarding your code so you might want to first run make normally.

dl: $(NAME).elf
	echo 'dow $(NAME).elf' > xmd.ini
	echo 'run' >> xmd.ini
	xmd
	rm xmd.ini

When you're done, type exit to quit xmd.

Automatic Debug

debug: $(NAME).elf
	mb-gdb &
	xmd

When you're done, type exit on the command line to quit xmd.

Programming the Board

If you're given a self-extracting archive, create a directory and move the file to it to avoid getting "tar bombed" and unzip it. Replace "update-s09-2" with the name of your file.

NAME=update-s09-2
mkdir ${NAME}
mv ${NAME}.exe ${NAME}
cd ${NAME}
unzip ${NAME}.exe

Now you should see a file called "update.bat". You can take a look at its contents to get a clue about the commands we'll need to run.

less update.bat

Use the arrow keys or page up/down keys to navigate and press q to quit. Essentially, we just need to run Xilinx's impact programmer with the given file. The script given to us will have a Windows-style path to where the self-extracting archive would have unpacked itself. Run the following command to fix this:

sed -i s/'c:\\.*\\'/'.\/'/ ProgramBoot.cmd

Now all we need to do is run the programmer. Make sure the Xilinx tools are in your path and that the Spartan board is connected via USB and powered on.

impact -batch ProgramBoot.cmd

Cable Lock Workaround

Sometimes you'll get an error with cable locking. Typing the following into xmd should fix this.

xclean_cablelock
