Re: Problem with Eurotech COM1273 Dual Channel CAN PC104 Module.

[Oliver Hartkopp <socketcan@hartkopp.net>]

Hello Khurram,

the speed is only set with the 'ip' tool now.

And regarding the former iomux handling it should be like this:

modprobe sja1000_isa port=0x200,0x204 irq=10,11 indirect=1,1

See the code for further module parameter details:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/net/can/sja1000/sja1000_isa.c

Regards,
Oliver
