Hallo,

danke für den Hinweis.
Wie im Handbuch beschrieben, habe ich diesen Treiber jetzt für SocketCAN bzw. netdev gebaut.

Code: Select all

Jetzt klappt auch das Bauen nicht mehr. :oops:

Danke für Ihre schnelle und kompetente Hilfe!

EDIT:
Es klappt wieder. Ich habe alles deaktiviert, außer die USB Schnittstelle.
Muss der Treiber jetzt dennoch irgendwie ins System eingebunden werden?

sudo insmod pcan.ko -> Klappt nicht
sudo modprobe pcan -> Klappt nicht

Hallo,

ja, der PI hat kein PCI, also bitte ohne PCI und PCC bauen, wie vorher auch, aber eben mit dem Netdev Schalter an....

:D

PS: klappt nicht ist sehr hilfreich......also entweder Fehlermeldung posten oder selbst Fehler suchen... :oops:

Genau das habe ich eben auch gemerkt. :D

Jetzt klappt alles - nur noch das Laden des Treibers nicht.

Immer noch dieser "Exec" Fehler und bei insmod das "module format".

Code: Select all

pi@raspberrypi:~/Prerequisites/peak-linux-driver-8.6.0/driver $ sudo insmod pcan.ko
insmod: ERROR: could not insert module pcan.ko: Invalid module format
pi@raspberrypi:~/Prerequisites/peak-linux-driver-8.6.0/driver $ sudo modprobe pcan
modprobe: ERROR: could not insert 'pcan': Exec format error

Bitte mal den PI mit sudo apt-get update sowie sudo apt-get upgrade aktualisieren, danach ein Neuboot und wieder die rpi-source Prozedur und die Treiberinstallation nochmals von vorne durchfuehren. Wurde da die Kernelversion zwischenzeitlich geaendert?

Ich bin in gewissermaßen an die Kernel-Version gebunden, da ich ein Echtzeit-Linux benötige. Und gerade in dem Setup habe ich alles weitere am laufen - bis auf den Peak Adapter.
Außerdem finde ich es verwunderlich, dass auf einem Debian der Adapter sofort funktioniert und auf einem Raspbian nicht.

Und zu Ihrer Frage:
Nein, die Kernelversion war immer auf der jetzigen. Da ist zwischenzeitlich nichts passiert.

Hi,

Raspian hat den SocketCAN im Config nicht automatisch aktiviert, der Kernel soll wohl schlank bleiben. Ich vermute mal dass rpi-source bei so einem speziellen Kernel versagt. Daher bitte mal pruefen ob Sie den Kernelsource Ihres RT Kernels woanders her bekommen. Dann sollte das auch mit dem SocketCAN Treiber klappen.

Andere Moeglichkeit waere die Kernelconfig anpassen fuer SocketCAN und den Kernel einmal neu erstellen. Dann haetten Sie die SocketCAN Treiber wie unter Debian bereits implementiert, und kein weiterer Treiber waere fuer den PCAN-USB notwendig. Das ganze steht auch hier im Forum in einem weiteren Thread zum RPI:

Guten Morgen,

ich habe es gestern noch einmal mit NETDEV versucht, leider funktioniert es immer noch nicht.
Habe noch etwas vergessen oder falsch gemacht?

Re: Raspberry mit USB PCAN

Raspian hat den SocketCAN im Config nicht automatisch aktiviert, der Kernel soll wohl schlank bleiben. Ich vermute mal dass rpi-source bei so einem speziellen Kernel versagt. Daher bitte mal pruefen ob Sie den Kernelsource Ihres RT Kernels woanders her bekommen. Dann sollte das auch mit dem SocketCAN Treiber klappen.

Andere Moeglichkeit waere die Kernelconfig anpassen fuer SocketCAN und den Kernel einmal neu erstellen. Dann haetten Sie die SocketCAN Treiber wie unter Debian bereits implementiert, und kein weiterer Treiber waere fuer den PCAN-USB notwendig. Das ganze steht auch hier im Forum in einem weiteren Thread zum RPI:

https://www.peak-system.com/forum/viewt ... =140#p8244
Der Kernel ist endlich fertig. Habe alles neu kompiliert und installiert.
Jedoch wurde bei der Installation der Kernel-Module bereits angezeigt, dass pcan.ko Mutexes und Spinlocks benötigt. Das war aber nur eine Warnung, dennoch evtl. interessant.

Möglicherweise habt ihr ja noch eine Idee, das macht mich gerade echt wahnsinnig. :D
