Programming software for Lone Dynamics FPGA boards
ldprog can be used to program the configuration SRAM or flash on Lone Dynamics FPGA boards.
There are two ways to use ldprog:
- Run ldprog on a Raspberry Pi and directly connect the target device to the Raspberry Pi GPIO pins
- Run ldprog on a Linux computer and use a USB interface device (see supported devices below)
apt-get install libusb-1.0-0-dev
make musli
apt-get install pigpio
make gpio

Note: Raspberry Pi Pico and Werkzeug must be loaded with the Müsli firmware. Keks, Eis, Bonbon and Kolibri provide a built-in interface device.
