Install Rasbian OS with the Raspberry Pi Imager, setup SSH, setup WiFi, setup the user e.g.

• User: pi

with

• Password: raspberry

• Connect with putty or Windows Powershell

  ssh PiUser@IP-Address
  

  e.g.:

  ssh mancloud@192.168.0.15
  

  send the following commands to the pi:

  sudo apt update
  sudo apt -y dist-upgrade
  sudo apt install build-essential libusb-dev libftdi-dev libgpiod-dev git cmake
  git clone https://github.com/matrix-io/xc3sprog
  mkdir xc3sprog/build
  cd xc3sprog/build
  cmake .. -DUSE_WIRINGPI=OFF
  make
  sudo make install
  

  now you need to copy the .jed file onto the Raspberry over ssh. With the Windows Powershell it would be:

  scp ./gc_ipl.jed mancloud@192.168.0.15:xc3sprog/build
  

  now the file is in the same directory as the xc3sprog. The file could be anywhere on the pi's filesystem but it makes it easier and then you have to edit the path for the file in the following command.

The KunaiGC uses the SOICbite-Interface to program the CPLD and Flash. You need an SOIC-8 Test Clip and modify it a little bit. Actually Mi213 has an awesome tutorial how to prepare the SOIC-8 Test Clip for this usecase. Thanks to Mi213 to let use refer to it :)

Now connect the SOICbite between the RaspberryPi and the KunaiGC

and send the following command with the Powershell:

```
sudo xc3sprog -c sysfsgpio_creator -j
```

if everything is soldered and connected correctly the output should be like this:

```
JTAG loc.:   0  IDCODE: 0x59604093  Desc:                       XC9536XL Rev: E  IR length:  8
```

now you know, that the CPLD is recognized correctly - we keep an eye on the  _**JTAG loc.:**_ which is  _**0**_ in this case and then we send the flash command to flash the .jed-file onto the CPLD

```
sudo xc3sprog -c sysfsgpio_creator -v -p 0 ~/xc3sprog/build/gc_ipl.jed
```

the CPLD will now be programmed and and verified at the end. If this is successful:

```
Success! Verify time xxxx.x ms
```

Now you need to solder and test it :)
