# cycloader
tool for programming FPGA. 

Current support:
* Trenz cyc1000 Cyclone 10 LP 10CL025 (memory and spi flash)
* Digilent arty 35T (memory)

## compile and install

This application uses libftdi1, so this library must be installed (and,
depending of the distribution, headers too)
```bash
apt-get install libftdi1-2 libftdi1-dev libftdipp1-3 libftdipp1-dev
```

To build the app:
```bash
$ make
```
To install
```bash
$ sudo make install
```
Currently, the install path is hardcoded to /usr/local

## Usage

```bash
cycloader --help
Usage: cycloader [OPTION...] BIT_FILE
