CYC1000 Binaries

Find the .at1, .rbf, .sof and .svf bitstream binaries under their category (arcades, computer, consoles).

Each binary should include in the filename the date when was made.

Older versions go into old folder.

File formats

• at1

  • It is a rbf format renamed to at1. Has the same properties as rbf format
  • It is the only format accepted by the STM32 multicore.
  • Following new Purple ATLAS board design, PS2 clk and data signals are exchanged and joystick pull-up resistors are added in Quartus.
  • In the future it is expected to work with newer and older ATLAS board versions, and with PS2 or USB keyboards. In the interim might only work with the newer purple board.

• rbf

  • Before latest Purple ATLAS board edition was the standard format.
  • It is the preferred format to program Atlas from a Raspberry Pi with programRBF
  • It can also be programmed with openFPGAloader from desktop PC with USB cable

• svf

  • Can be programmed with openFPGAloader from desktop PC with USB cable

• sof

  • sof is the standard Quartus format and is only programmable with Quartus tool usign the USB cable.

Instalación del cargador de cores programRBF en la FPGA

Nota: vamos a trabajar desde el directorio /home/pi que es el que aparece por defecto al arrancar el terminal Linux con el usuario "pi".

• Instala la librería WiringPi:

  wget https://project-downloads.drogon.net/wiringpi-latest.deb
  sudo dpkg -i wiringpi-latest.deb
  

• Compila el ejecutable para cargar los cores:

  wget https://raw.githubusercontent.com/shaeon/programrbf/main/programrbf_v01.cpp
  g++ programrbf_v01.cpp -lwiringPi -o programrbf
  

Arranca los cores desde el terminal Linux de la SBC

• Copia los cores con extensión .rbf a la tarjeta SD, en la partición "rootfs", directorio ""/home/pi".

• Carga el core con el ejecutable programrbf (el ejemplo carga el msx_atlas.rbf de MSX1):

  ./programrbf msx_atlas.rbf 17 22 4 27
  

Script para cargar un core automáticamente al arrancar la SBC

• Ejecuta los siguientes comandos en el terminal de Línux:

  crontab -e
  #selecciona por ejemplo nano y al final del fichero cron añade lo siguiente:
  @reboot ~/programrbf msx_multicore2.rbf 17 22 4 27

Flash bitstream to FGPA with Desktop PC

Quartus (sof files) (Linux/Max/Windows)

• From IDE (Linux / Windows)

Use the programmer tool

• From Command line (Linux / similar for windows)

Update with your own PATHs to Quartus and sof filename:

cd path/to/output_files/
export PATH="/path/to/quartus/bin:$PATH"
quartus_pgm --mode=jtag -o "p;patth/to/core.sof"

Example:

cd cyc1000/output_files/
export PATH="/home/jordi/bin/intelFPGA_lite/17.1/quartus/bin:$PATH"
quartus_pgm --mode=jtag -o "p;gameboy_deca.sof"

OpenFPGAloader (rbf, AT1 & svf) (Linux / Mac)

• For AT1 files rename it first to rbf extension

• Install OpenFPGAloader . For windows find binary here and follow tutorial instructions.

• Execute

  #either
  openFPGALoader -b cyc1000 filename.svf
  #or
  openFPGALoader -b cyc1000 filename.rbf
  

Midnight Commander Launcher

GNU Midnight Commander is a free file manager, and it started as a clone of Norton Commander.

Install Midnight Commander and edit file extension scripts. Menú command > Edit extension File.

Add following extensions to the end of the mc.ext file and adapt the script to your own environtment (mine is Linux).

After that launch mc command from the folder you have all the cores and double click on each extension to program it though USB cable connected to the CYC1000 FPGA.

Content of mc.ext for Multicore extensions for ATLAS:

### MULTICORE ###
