Can't start ESD CAN-USB/2

Can't start ESD CAN-USB/2

[Francesco Giovannini]

Hi guys!

I am running OpenSuse 12.2, kernel 3.4.63-2.44-desktop. I downloaded and 
installed libsocketcan v0.0.9 and canutils v4.0.6. I then compiled the 
esd_can2 module and modprobed it correctly. When i plug in my CAN-USB/2 
device i get the following from dmesg:

    [186823.262021] usb 1-10: new high-speed USB device number 22 using
    ehci_hcd
    [186823.826031] usb 1-10: device not accepting address 22, error -71
    [186823.877025] hub 1-0:1.0: unable to enumerate USB device on port 10
    [186827.879018] usb 1-10: new high-speed USB device number 24 using
    ehci_hcd
    [186827.995429] usb 1-10: New USB device found, idVendor=0ab4,
    idProduct=0010
    [186827.995432] usb 1-10: New USB device strings: Mfr=1, Product=2,
    SerialNumber=3
    [186827.995435] usb 1-10: Product: USB2292
    [186827.995438] usb 1-10: Manufacturer: esd electronic system design
    gmbh (www.esd-electronics.com)
    [186827.995440] usb 1-10: SerialNumber: GM001950
    [186827.997824] esd_usb2 1-10:1.0: can0: device can0 registered

The device appears to be correctly recognised and the can0 interface is 
ready to be used. I then set the bitrate and several other paramters with:

    # canconfig can0 bittiming  prop-seg 2 phase-seg1 12 phase-seg2 5
    sjw 1 brp 3 tq 50

    can0 bittiming:
         tq: 50, prop-seq: 2 phase-seq1: 12 phase-seq2: 5 sjw: 1, brp: 3
    can0 bitrate: 1000000, sample-point: 0.750

However when i try to start the interface with # ifconfig can0 up, I get 
the following error:

    SIOCSIFFLAGS: Invalid argument

If I look at the details for the can0 interface it seems that all the 
configuration parameters I sent earlier are not taken into account:

    # ip -d link show can0
    16: can0: <NOARP,ECHO> mtu 16 qdisc noop state DOWN mode DEFAULT qlen 10
         link/can
         can state STOPPED (berr-counter tx 0 rx 0) restart-ms 0
         bitrate 0 sample-point 0.000
         tq 0 prop-seg 0 phase-seg1 0 phase-seg2 0 sjw 0
         esd_usb2: tseg1 1..16 tseg2 1..8 sjw 1..4 brp 1..1024 brp-inc 1
         clock 60000000

Also, for reference sake, my kernel is compiled with 
CONFIG_CAN_CALC_BITTIMING=y. I am of course running all of these 
commands as root.

I must say this is a very weird behaviour. I have been struggling 
without being able to see the light and I really hope one of you guys 
might have a clue about what is going on.


Thanks a lot!

Try to set the bittiming with this command:

    canconfig can0 bitrate 1000000

Does this work?

[Francesco Giovannini]

Hi Mark,

I tried #canconfig can0 bitrate 1000000

    can0 bitrate: 1000000, sample-point: 0.750

I am however still unable to successfully start the can0 interface with 
# ifconfig can0 up. Same error shows up.

What's the outout of "canconfig can0" after "canconfig can0 bitrate 1000000"

Please try as root and send me the output:

Weird. Looks like canconfig bitrate acts like it is unplugging and plugging the device. Is this normal?

Why do you have compiled the esc_can2 by yourself? It is part of the
kernel. Is it not activated on suse?

Please don't top post.

Have you used the kernel sources provided by suse? If not, try these.
Try a different USB port on the machine, if the CAN adapter has a USB
cable that is removable, swap it too. If it's still failing try a
different machine.

If you have a different linux machine I suggest to test, just to make
sure the USB adapter works under linux. Although the kernel is quite new
can you try a newer one?

Can you make a firmware update of the USB adapter? Does the adapter work
under windows?

Okay, the device is working. Even under Linux :)

But the Suse is a different machine, so different USB
controller/hardware and different USB driver.

It's not the canutils, they just send the parameters into the kernel.
The kernel driver hasn't changed much. Feel free to contact the driver
developer Matthias Fuchs <matthias.fuchs@esd.eu>, keep the mailinglist
on Cc, if possible.

Marc

Hi Matthias,

I was told to keep the linux-can mailing list in the loop.

I did not solve the problem. I believe it might be due to a USB 
controller problem as Marc suggested. For information sake here are the 
output of dmesg, lsusb and lspci as I plug in the device:

Re: Can't start ESD CAN-USB/2

[Matthias Fuchs]

Hi Francesco,

I forwarded this issue to our support. We will try to reproduce
the issue here with your setup (Suse 12.2) and will come back to you
later.

We will keep the list on cc as far this has to do with linux-can.

Can you answer this question by Marc, please. Are you using a SuSE
provided kernel module or did you built it yourself? If so, how?

Are you using a 32 or 64 bit SuSE maschine?

Can you answer Marc's question about the origin of the kernel module?
Did you built it yourself or are you using SuSE provided modules?
How did you built the module and from what sources?

Are you running on a 32 or 64 bit system?

RE: Can't start ESD CAN-USB/2

[Francesco Giovannini]

Hi Matthias,

I am running a 64bit system, using the "desktop" kernel package from 
OpenSuSe.
I used the linux-source package provided in OpenSuSe 12.2, copied the 
.config, added the module via menuconfig and then ran
     make M=./drivers/net/can/usb in the kernel source tree

to build the module.

Used packages:

     kernel-desktop
     kernel-desktop-devel
     kernel-default-devel
     kernel-devel
     kernel-source
     kernel-syms


Below are the output of uname and lsb_release:
