Most Xilinx FPGA devices contain an embedded, unique device identifier
called the "Device DNA". The identifier is nonvolatile, permanently
programmed into the FPGA, and is unchangeable providing a great serial
/ tracking number.
Debugging was done in https://github.com/timvideos/HDMI2USB/issues/36

The Pipistrello is a low cost FPGA board with a Xilinx
Spartan6 LX45, a SPI flash and onboard FTDI JTAG.
This board is a good example use case for the jtagspi
flash driver talking through a proxy bitstream.

Many FPGA board speak JTAG and have a SPI flash for their bitstream
attached to them. The SPI flash is programmed by first uploading a
proxy bitstream to the FPGA that connects the JTAG interface to the
SPI interface if the IR contains a certain USER instruction. Then the
SPI flash can be erase, written, read directly through the JTAG DR.
The JTAG and SPI signaling is compatible. Such a proxy bitstream only
needs to connect TDO-MISO, TDI-MOSI, TCK-CLK, and the activate the
chip select when the IR contains the special instruction and the JTAG
state machine is in the DR-SHIFT state.
