------
Tools 
------
You need to build vhdl ROM image files from the binary file :
 - Unzip the roms file in the tools/berzerk_unzip directory
 - Double click (execute) the script tools/berzerk_unzip/make_berzerk_proms.bat to get the following files

berzerk_program1.vhd
berzerk_program2.vhd

*DO NOT REDISTRIBUTE THESE FILES*

The script make_berzerk_proms uses make_vhdl_prom and and duplicate_byte executables delivered both in linux and windows version. The script itself is delivered only in windows version (.bat) but should be easily ported to linux.

Source code of make_vhdl_prom.c and and duplicate_byte.c is also delivered.

---------------------------------
Compiling for de10_lite
---------------------------------
You can rebuild the project with ROM image embeded in the sof file. DO NOT REDISTRIBUTE THESE FILES.
4 steps

 - put the VHDL rom files into the project directory
 - rebuild berzerk_de10_lite
 - program berzerk_de10_lite.sof into the fpga 

------------------------
End of file

You can’t perform that action at this time.
