Hi,
My dongle has arrived and seems to be OK under windows.
I am now trying to install it under linux but things not looking good so
far.
from
/lib/modules/2.6.16-xen-3/kernel/drivers/xenomai/can/sja1000
I ran
$>depmod xeno_can_peak_dng.ko
$>modprobe xeno_can_peak_dng type=epp io=0x378 irq=7
but the result is:
FATAL: Error inserting xeno_can_peak_dng (xeno_can_peak_dng.ko): No such
device
The little led is glowing. And the dongle is even plugged in to the
only parallel port my machine has :)
Nothing is connected to the output of the dongle at this stage.
Am I missing something fundamental here?
Maybe a conflict with parport_pc.
Yes, because it already grabs/registers the interrupt:
$ grep par /proc/interrupts
7: 3 XT-PIC parport0
Wolfgang, do we always have to remove that module, or is there a chance
to cooperate with it without loosing real-time? When removing the Linux
parport layer, there is the risk that the port is powered off (see
irqbench), and xeno_can_peak_dng does not account for this yet.
That's the tricky part, indeed. On my Laptop I need to disabled the
parport support completely for proper operation. On my PC that does not
work for some strange reasons. I need parport loaded and parport_pc
removed. We still need the PNP fix to avoid the problem you described
with power off.
Wolfgang.
