ECP5 Mini Projects

August 29, 2021 ยท View on GitHub

A collection of projects for the ECP5 Mini FPGA development board.

These projects are my own, and probably have more mistakes and bad practices in them than you can poke a stick at. Use them at your own risk.

Verilog

Verilog projects are in verilog, and after changing into the project directory have the below options.

  • make to build the project
  • make flash to program flash over JTAG using ecpprog and a FTDI cable.
  • make sram to program SRAM as above.
  • make dfu to flash the board over USB. Requires the bootloader to be flashed to the board first.
  • make DEVICE=25k to build for a non 12F ECP5.
  • make simulate to simulate the design with iverilog using the $(PROJ)_tb.v simulation file.
  • make new NAME="name" to copy current project to new folder called name along with changing all in text references.

Litex

Litex projects are in litex , and after changing into the project directory run python3 ecp5_mini.py --build --load

Append --device=25F to build for a non 12F ECP5.

nMigen

nMigen projects are in nmigen, and after changing into the project directory run python3 project.py.

Thanks

Thanks to Konrad Beckmann for his Pergola Projects which this was based off.

Thanks to Greg Davill for the soc-hr example.
