Foboot: The Bootloader for Fomu

Foboot is a failsafe bootloader for Fomu. It exposes a DFU interface to the host. Foboot comes in two halves: A Software half and a Hardware half.

Building the Hardware

The hardware half is written in LiteX, and uses lxbuildenv to handle Python dependencies. Hardware is contained within the hw/ directory. You must install software dependencies yourself:

Python 3.5+
Nextpnr
Icestorm
Yosys
Git

Subproject dependencies will be taken care of with lxbuildenv.

Usage

To build, run foboot-bitstream.py:

python3 .\foboot-bitstream.py

There are multiple build options available. Use --help to list them.

Build files will be generated in the build/ directory. You will probably be most interested in build/gateware/top.bin and build/software/include/generated/.

Tests

You can run tests by using the unittest command:

python .\lxbuildenv.py -r -m unittest -v valentyusb.usbcore.cpu.epfifo_test.TestPerEndpointFifoInterface

Building the Software

Software is contained in the sw/ directory.
