Fomu build using the Amaranth toolchain.

To set up a Linux machine for easy passthrough:

# Allow 'plugdev' to access Fomu USB IDs
cat extras/99-fomu.rules | sudo tee /etc/udev/rules.d/99-fomu.rules
# Disable power-saving autosuspend on Fomu IDs
cat extras/fomu-serial.conf | sudo tee /etc/tlp.d/fomu-serial.conf

Then try:

. ./enter.sh
python usb_serial.py
