ldprog
Programming software for Lone Dynamics FPGA boards
Overview
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)
Installation for use with Müsli or Raspberry Pi Pico (Ubuntu)
apt-get install libusb-1.0-0-dev
make musli
Installation for use with Raspberry Pi GPIO (Raspbian)
apt-get install pigpio
make gpio
Usage
Display help:
./ldprog -h
Supported Target Devices
- Riegel Computer
- Eis Computer
- Bonbon Computer
- Keks Game Console
- Brot FPGA Board
- Kröte FPGA Board
- Winzig Logic Module
- Kolibri FPGA Dongle
Supported Interface Devices
Note: Raspberry Pi Pico and Werkzeug must be loaded with the Müsli firmware. Keks, Eis, Bonbon and Kolibri provide a built-in interface device.
