R5U87x Userspace Tools Version 0.2.1, 2009/11/22 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 ========== Ubuntu $ sudo apt-get install libglib2.0-dev libusb-dev build-essential gcc automake mercurial $ hg clone http://bitbucket.org/ahixon/r5u87x/ $ cd r5u87x $ make $ sudo make install $ sudo r5u87x-loader --reload The loader will automatically be run on boot when it detects your webcam. Installation from source ======================== Simply install the dependencies required above on your system, then run 'make'. Now you can proceed to installing the tool system-wide: # make install If you have udev installed, your system will automatically load the firmware to the camera, and then reload the uvcvideo module at boot time. Please note that the loader is installed system-wide as 'r5u87x-loader', but compiles as just 'loader'. You can either reboot or follow the instructions below. Usage ===== To upload the firmware to your camera, simply run (as root): # loader --reload 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: # loader --force-clear There are also useful arguments for testing, see docs/extracting_ucode.txt Bugs ==== The following issues are known already, so please *do not* report them (you can, however, subscribe to any of these tickets): * Broken pipe (code 32) - http://www.bitbucket.org/ahixon/r5u87x/issue/6/ * Distorted/stripy video - http://www.bitbucket.org/ahixon/r5u87x/issue/17/ * HP Pavillion dv9000 or similar aren't detected (make sure you uncomment only *ONE* device, not both) - http://bitbucket.org/ahixon/r5u87x/issue/26/ * Upside down video - http://www.bitbucket.org/ahixon/r5u87x/issue/7/ Please note WDM devices WILL NOT WORK. You can check what type of model you have by looking at the model chart found in docs/model_matrix.txt. If you're running a WDM based device, you can try to look on the internet for a patched version of r5u870, however it will probably not work with more recent kernels. You should also register, otherwise you may not get notifications of any replies to your bug. Report any bugs by creating a new ticket at http://www.bitbucket.org/ahixon/r5u87x/issues/new/. If possible, make sure that the bug you have hasn't already been reported by searching the issue list.

See the included file 'COPYING' for license. The files located under the 'ucode' directory were derived from usbsnoop/sniffusb tracing of various Windows drivers, including some named Mvc25u870.sys, 5U870CAP.sys, and R5U870FLx86.sys. 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.
