To build this repository, simply run `make`.
## Test Jig Setup
The EVT boards can be attached directly to the Raspberry Pi as a "hat". When building a test jig, attach wires according to the following image:
![Raspberry Pi Pinout](pinout.png)
The only pins that are required are 5V, GND, CRESET, SPI_MOSI, SPI_MISO, SPI_CLK, and SPI_CS.
You can improve performance by attaching SPI_IO2 and SPI_IO3 and running `fomu-flash` in quad/qpi mode by specifying `-t 4` or `-t q`.
You can get serial interaction by connecting the UART pins, but they are not necessary for flashing.
## Loading a Bitstream
The most basic usecase is to load a program into configuration RAM. This is a very quick process, and can be used for rapid prototyping.
