This layer contains recipes for Hardware Description Languages (HDL) tools, which include tools for simulation, synthesis, place and route, FPGA bitstream packing/analysis as well as example projects.
Only projects released under open source licenses are contained in this layer.
To build this target, set MACHINE = "picosoc" in your local.conf and build the
picosoc-hx8k recipe with bitbake picosoc-hx8k. The built bitstream and
firmware are populated into the deploy/images/picosoc directory on completion.
Linux on LiteX-VexRiscv (Versa ECP5)
This example requires the meta-riscv layer.
To build this target, set MACHINE = "versa-ecp5" in your local.conf and build
core-image-minimal. The built bitstream, firmware, linux kernel, root
filesystem and device tree are populated into the deploy/image/versa-ecp5
directory on completion. Follow the documentation provided by the project itself
to boot the images.
A load task exists to execute the --load command of make.py. To run the
task execute bitbake linux-on-litex-vexriscv -c load. In order to use the
LiteX terminal, build bitbake litex-native -c addto_recipe_sysroot and use
oe-run-native litex-native lxterm ... to run lxterm.
Additionally the Verilator simulation can be run with bitbake linux-on-litex-vexricv -c sim. This will start the simulation in a
terminal (similar to devshell).
The foboot recipe is provided in order to build the Fomu's boot loader. Set
the MACHINE = "fomu" in local.conf and build foboot. The bitstream is
populated into the deploy directory.
The micropython and fomu-workshop-litex-rgb recipes can be used to build the
micropython firmware and bitstream respectively.
Note: dfu-util-native is provided by meta-oe, and can be built and then run
using oe-run-native. bitbake dfu-util-native -c addto_recipe_sysroot and
oe-run-native dfu-util-native dfu-util ...
