The Cypress CY7C68013A FX2 High Speed USB Microcontroller on a Digilent X-Board is easily programmable without any board modifications. Wolfgang Wieser's excellent Open Source FX2 Development Website has very detailed instructions. The following are some useful notes for development under Ubuntu Linux.

You can always return to the default Digilent X-Board firmware by unplugging your X-Board from USB and any power supply and then re-plugging it in.

You will need to install sdcc to compile CY7C68013A firmware and gcc to compile the programming software.

A@B:~$  sudo apt-get install build-essential gcc binutils sdcc libusb-dev libtool
...

Extract and compile cycfx2prog:

A@B:~$  cd cycfx2prog-0.47/
A@B:~/cycfx2prog-0.47$  make
gcc -pipe -c -O2 -fno-rtti -fno-exceptions -DCYCFX2PROG_VERSION=\"0.47\" -W -Wall -Wformat cycfx2prog.cc
gcc -pipe -c -O2 -fno-rtti -fno-exceptions -DCYCFX2PROG_VERSION=\"0.47\" -W -Wall -Wformat cycfx2dev.cc
cycfx2dev.cc: In member function ‘int CypressFX2Device::_ProgramIHexLine(const char*, const char*, int)’:
cycfx2dev.cc:393:3: warning: comparison of unsigned expression >= 0 is always true
gcc -pipe -lusb cycfx2prog.o cycfx2dev.o -o cycfx2prog

Connect your X-Board to your PC. It will show up under lsusb:

A@B:~/cycfx2prog-0.47$  lsusb
Bus 001 Device 024: ID 1443:0005 Digilent 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

A@B:~/cycfx2prog-0.47$  ./cycfx2prog -id=1443.0005
Using ID 1443:0005 on 001.024.

Extract the examples and edit the Makefile so that CYCFX2PROG points to the location of cycfx2prog and includes the id of the X-Board:

A@B:~/cycfx2prog-0.47$ cd hello_world_ram/
A@B:~/cycfx2prog-0.47/hello_world_ram$ gedit Makefile 

  CYCFX2PROG = ../cycfx2prog -id=1443.0005

https://raw.githubusercontent.com/ha7ilm/opendous/master/Pictures/X-Board_FX2_Programming.jpg

You can now compile and run the examples.

A@B:~/cycfx2prog-0.47/hello_world_ram$  make
sdcc -mmcs51 -I../include hello.c

A@B:~/cycfx2prog-0.47/hello_world_ram$  sudo make run

To avoid having to run the software using sudo you will need to create a USB access rule.

sudo gedit /etc/udev/rules.d/99-xboard.rules

Insert the following rules:

SUBSYSTEM=="usb", ACTION=="add", SYSFS{idVendor}=="1443", SYSFS{idProduct}=="0005", MODE="666", GROUP="plugdev"
BUS=="usb", ACTION=="add", SYSFS{idVendor}=="1443", SYSFS{idProduct}=="0005", MODE="666", GROUP="plugdev"
