Need a few feet, two 2x20 headers, and a SMA.
iceprog is the software used to put the fpga on the flash storage on the board, which will be read by the fpga on boot.
The easiest way is to
sudo apt install fpga-icestorm
If this doesn’t work, then this may work:
sudo apt-get install libftdi-dev git gcc git clone https://github.com/cliffordwolf/icestorm.git cd iceprog make sudo make install
This will create and install the iceprog utility, used to flash the fpga program (bitstream).
Prepare the jumper here :
Then, plug an usb cable from the RPi to the board (not connected using the raspberry pi header).
Check that the FTDI device is well created by typing:
and then flash the FPGA by doing:
wget https://github.com/kelu124/un0rick/raw/master/bins/v1.1.bin iceprog v1.1.bin
This should flash the board:
I’ve been using a RPi4 with a ribbon cable to connect to the board, leaving the jumper on, putting one to select the high voltage level, connecting a piezo.. and that’s it.
Then, for example to discover the board using Python, you can use the library:
git clone email@example.com:kelu124/pyUn0-lib.git cd pyUn0-lib python pyUn0.py test python pyUn0.py single
It will download the lib, then you should see with the ‘test’ option a LED blink, then the “single” option will allow you to capture a single line.
I’ve used this exact setup to get the lib examples ( https://github.com/kelu124/pyUn0-lib ).
