antrax Datentechnik GmbH info@antrax.de - www.antrax.de Webcam Installationsguide für das YADE-Board Dieser Installationsguide zeigt anhand des Beispiels der "Logitech® Webcam C250" wie eine Webcam auf der YADE-Baugruppe zum funktionieren gebracht werden kann. Benötigte Komponenten • • "Logitech® Webcam C250" oder eine andere UVC-USB-Kamera das Paket uvcvideo.tar.gz Es wird davon ausgegangen, dass eine unveränderte YADE-Baugruppe vorliegt und Grundkentnisse über die Inbetriebnahme und den Umgang mit Linux vorhanden sind. Vorbereitung Die YADE-Baugruppe ist in Betrieb zu nehmen und das Paket uvcvideo.tar.gz in das Dateisystem zu kopieren. Es wird empfohlen hierfür das Verzeichnis /var/tmp zu nutzen, und wie in "YADE_Kurzanleitung" beschrieben herunterzuladen. starting pid 357, tty '/dev/console': '/bin/sh' #cd /var/tmp #rz --ymodem rz waiting to receive.CCC Nach dem Herunterladen muss das Paket entpackt werden. # tar -xvzf uvcvideo.tar.gz uvcvideo/ uvcvideo/install.sh uvcvideo/modules.dep uvcvideo/videodev.ko uvcvideo/v4l2-int-device.ko uvcvideo/v4l2-common.ko uvcvideo/v4l1-compat.ko uvcvideo/uvcvideo.ko uvcvideo/checksums uvcvideo/uvccapture # Von den aufgelisteten Dateien werden zunächst nur diejenigen benötigt, welche die Endung .ko haben. -1Hasenbrink 4, 32052 Herford, Germany Tel. +49 (0) 5221 929660 Fax +49 (0) 5221 9296628 antrax Datentechnik GmbH info@antrax.de - www.antrax.de "ko" steht hier für "kernel Object" und ist ein "Binärschnipsel" der als, so genanntes Modul, in den Kernel eingehängt wird. Dieses Einhängen muss in einer bestimmten Reihenfolge geschehen, sonst funktioniert es nicht! Zunächst müssen die USB-Schnittstellen aktiviert werden, dann sollten die auf dem YADEBoard schon vorhandenen Module für USB und I²C1 geladen werden. Danach können mit dem Befehl insmod die Module eins nach dem anderen geladen werden. # cd uvcvideo/ # echo O1 >> /dev/at91sam9260_gpio.32 # modprobe usbcore usbcore: registered new interface driver usbfs usbcore: registered new interface driver hub usbcore: registered new device driver usb # modprobe ohci-hcd at91_ohci at91_ohci: AT91 OHCI at91_ohci at91_ohci: new USB bus registered, assigned bus number 1 at91_ohci at91_ohci: irq 20, io mem 0x00500000 usb usb1: configuration #1 chosen from 1 choice hub 1-0:1.0: USB hub found hub 1-0:1.0: 2 ports detected # usb 1-2: new full speed USB device using at91_ohci and address 2 usb 1-2: configuration #1 chosen from 1 choice # insmod v4l1-compat.ko # modprobe i2c-core # insmod videodev insmod: can't open 'videodev': No such file or directory # insmod videodev.ko Linux video capture interface: v2.00 # insmod v4l2-common.ko # insmod v4l2-int-device.ko # insmod uvcvusb 1-2: USB disconnect, address 2 # insmod uvcvideo.ko usbcore: registered new interface driver uvcvideo USB Video Class driver (v0.1.0) # 1 das I²C-Modul wird vom v4l2-common Modul genutzt.

ACHTUNG: das Script greift an einer empfindlichen Stelle des Systems ein. Vorhandene Treiber werden überschrieben. Es wird empfohlen ein Backup dieser Treiber durchzuführen. Kopieren Sie hierzu alle Dateien aus "/lib/modules/2.6.24-rc5rt1/kernel/drivers/media/video/" beispielsweise auf einen USB-Stick! # ./install.sh /lib/modules/2.6.24-rc5-rt1/modules.dep: OK cp modules.dep /lib/modules/2.6.24-rc5-rt1/modules.dep mkdir /lib/modules/2.6.24-rc5-rt1/kernel/drivers/usb/media cp uvcvideo.ko /lib/modules/2.6.24-rc5-rt1/kernel/drivers/usb/media/uvcvideo.ko cp v4l1-compat.ko /lib/modules/2.6.24-rc5-rt1/kernel/drivers/media/video/ cp v4l2-common.ko /lib/modules/2.6.24-rc5-rt1/kernel/drivers/media/video/ cp v4l2-int-device.ko /lib/modules/2.6.24-rc5-rt1/kernel/drivers/media/video/ cp videodev.ko /lib/modules/2.6.24-rc5-rt1/kernel/drivers/media/video/ cp uvccapture /usr/bin # Jetzt ist es möglich mit "modprobe" den Treiber für die Webcam mit einem einzigen Befehl zu laden. # modprobe uvcvideo usbcore: registered new interface driver usbfs usbcore: registered new interface driver hub usbcore: registered new device driver usb Linux video capture interface: v2.00 usbcore: registered new interface driver uvcvideo USB Video Class driver (v0.1.0) # Wenn das überschreiben der vorhandenen Treiber nicht gewünscht ist, ist es möglich die neuen Treiber in ein eigenes Verzeichnis zu kopieren, und sie dann immer auf die oben beschriebene Weise zu laden bzw. ein Skript dafür zu schreiben. -4Hasenbrink 4, 32052 Herford, Germany Tel. +49 (0) 5221 929660 Fax +49 (0) 5221 9296628 antrax Datentechnik GmbH info@antrax.de - www.antrax.de Unterstützte Kameras Die folgenden Kameras werden vom "uvcvideo" Treiber Unterstützt.
