Description
The Firehat is part of the ‘equip-1’, a portable MRU, or Memory Recording Unit. You can use this HAT’s FireWire (IEEE 1394) interface to ingest footage either played back via tape (e.g. MiniDV) or directly through a camera as an input.
It records using dvgrab (sudo apt install -y dvgrab), and requires the CONFIG_FIREWIRE_OHCI option in the Linux kernel.
Pi Setup
Recompile the Linux Kernel with Firewire support
Recompile the Linux kernel, enabling the following features:
CONFIG_FIREWIRE(Device Drivers -> IEEE 1394 (FireWire) support -> FireWire driver stack)CONFIG_FIREWIRE_OHCI(Device Drivers -> IEEE 1394 (FireWire) support -> FireWire driver stack -> OHCI-1394 controllers)
Configure Pi Boot options
At the end of /boot/firmware/config.txt, under [all], add:
dtparam=pciex1
dtoverlay=pcie-32bit-dma
At the end of the line in /boot/firmware/cmdline.txt, add:
pcie_aspm=off
Equip-1 Setup
The OLED display and buttons use the Pi’s GPIO to display status information and start/stop recordings directly. You need to install additional software to get them to work.
See the equip-1 GitHub project or this HAT’s linked GitHub issue for more info.
