transmitest und receivetest not working

[KatharinaB]

I am using the PCAN-PCI Single Channel (IPEH-002064) with the library v8.5.1

./lspcan -T -t -i shows:

and my kernel is 4.13.0-32-generic and it is also up-to-date

I connected a device (with 120Ohm) to the can interface thats sends messages with a bitrate of 1Mbit/s
Unfortunately the receive and send tests do not seem to work:

Hello,

Code: Select all

[ 3816.932785] pcan: __pcan_ioctl(cmd=21505): unsupported cmd (dir=0 type=84 nr=1 size=0)

cmd=21505 is absolutely unknown. If this cmd comes from receivetest, so it looks like there's a problem between user and kernel spaces.

Could you please give us the result of:

Code: Select all

$ uname -a

and, also, the output of the command that built everything in the driver, that is:

Code: Select all

$ cd peak-linux-driver-8.5.1
$ make clean
$ make
$ sudo make install

Thanks.

[KatharinaB]

Ok. So everything seems ok (except you're running an old gcc).

Now, load the new driver:

Code: Select all

$ sudo rmmod pcan
$ sudo modprobe pcan

Then, give us the output of:

Code: Select all

$ dmesg | grep pcan

Next, launch the receive application

Code: Select all

$ receivetest -f=/dev/pcan0 -b=0x0014 -e

Finally, open another shell window and while receivetest is running, give us (again) the output of:

Code: Select all

$ dmesg | grep pcan

Regards,

[KatharinaB]

The first output after loading the driver is:

Code: Select all

thanks for your help

Ok. Up to now, everything is ok.

What does say the running receivetest? If your /dev/pcan0 is connected to your CAN bus, you should see something...

FYI, instead of receivetest, you could use the (new) pcanfdtst tool which gives more info from the CAN bus. Try:

Code: Select all

$ pcanfdtst rx -b 1M /dev/pcan0

Regards,

[KatharinaB]

if I try pcanfdtst rx -b 1M /dev/pcan0
it returns

Code: Select all

1517229872~691085 /dev/pcan0  > BUS STATE=ACTIVE   [Rx:0 Tx:0]

and after I terminate it:

Code: Select all

/dev/pcan0 > [packets=0 calls=1 bytes=0 seq_err=0]
received frames: 0

the reveivetest retuns:

Code: Select all

./receivetest -f=/dev/pcan0 -b=0x0014 -e

[S.Grosjean]

Hi,

Well everything is ok for us. Status=0x0020 says nothing has been received by the driver from the CAN bus.
Can you check whether some frames are present on the CAN bus?

Regards,

Stéphane

[KatharinaB]

Hello,

I have checked both devices with a can-to-usb adapter and a can-monitoring-program on a different computer and they were both sending messages. Are there maybe some basic settings I need to change on the computer

thanks for the help.

Hi,

When there's traffic on the CAN bus, type:

Code: Select all

$ pcanfdtst rx -b 1M /dev/pcan0

Then, from another shell window:

Code: Select all

$ cat /proc/pcan > /tmp/pcan_1

Then:

Code: Select all

$ pcanfdtst tx -b 1M -i 0x123 -n 100 -l 8 /dev/pcan0 > /tmp/pcanfdtst_tx_100

Then redo:

Code: Select all

$ cat /proc/pcan > /tmp/pcan_2

Finally, send us /tmp/pcan_1, /tmp/pcanfdtst_tx_100 and /tmp/pcan_2" (or copy-paste then) please.

Thanks and regards,

Stéphane
