Hello SocketCANers,
I bought 3 ESD CAN-USB/2 units for a project, and I'm unfortunately
having problems getting them to work with linux. I'm using the latest
ubuntu, 11.04 I believe on x86 laptop.
Here are the details to get the conversation going. I have the
CAN-USB/2 plugged into the laptop, but no CAN network attached to it.
I'm using the latest ubuntu, linux kernel 2.6.38
the 'dmesg' log shows the CAN-USB/2 is seen:
"esd_usb2 2-1:1.0: device can0 registered"
now I do the following:
"modprobe can"
"modprobe can_raw"
"modprobe can_bcm"
and in the dmesg log all this appears to work fine.
then finally:
"ip link set can0 up type can bitrate 250000"
but this fails, I get back: "RTNETLINK answers: Invalid argument"
and in the dmesg log, I get this entry:
"esd_usb2 2-1:1.0: bit-timing calculation not available"
Can anyone help?
According to the man page for "ip", the "bitrate" parameter is invalid
(does not exist).
What am I missing?
Thanks all!
J
