R5U87x Userspace Tools Version 0.2.2, 2020/09/21
Introduction
This project is an attempt to produce a group of useful usespace tools for managing cameras based on Ricoh R5U87x chipsets.
You will still need to depend on such kernel drivers like uvcvideo to get the video stream out of the device.
Supported devices
See docs/model_matrix.txt
Compilation
To compile the tools, it is required you have the following prerequisites installed:
- GCC
- Automake
- libusb development packages (libusb-dev or similar)
- GLib 2.0 development packages (libglib2.0-dev or similar)
Quickstart
Usage
To upload the firmware to your camera, simply run (as root):
# ricoh-webcam-loader
Do note that this only lasts while the camera still has power to it. Shutting down and starting up again will cause the camera to lose its state. Rebooting, however, won't.
If your camera appears to be playing up, you can try forcefully resetting it:
# r5u87x-loader --force-clear
There are also useful arguments for testing, see docs/extracting_ucode.txt

Acknowledgements
Huge kudos to Sam Revitch for writing the original r5u870 driver. Additional thanks to those who helped Sam develop the driver.
Many thanks to Willem van Engen for working on getting this included into Ubuntu, as well as helping me with my Makefile writing, writing the udev template and awk/sed scripts, and creating a Debian package.
Thanks to Gonzalo Alvarez for testing the 1812 driver and providing usbsnoop traces of the device.
Thanks to Utz-Uwe Haus for getting the Sony VGP-VCC7 firmware extracted, and providing a patch against the original r5u870 driver, and providing the recode-fw.scm script.
Some friendly folk on the Ubuntu Forums for providing extracted version of firmwares and their associated version numbers.
Thanks to 'franz' for providing an updated version of 183b driver, and testing.
