Hello,

Ok, thank you for your answer. v1.3.0 is the official release.

Now let's start from the beginning please:
What kind of "PEAK USB" device are you talking about? Can you give us its part number (IPEH-00xxxx)?
Can you give us the "ip link set" command you use to set the canX channel UP ...

Hi,

Can you give us the firmware version that runs into the PCAN-minPCIe please? You should be able to get it with: or according to the driver you run.

Hi,

As you said, by using PCAN-Basic, or as written in https://www.peak-system.com/produktcd/P ... on_eng.pdf in page 19 as well as in page 23.

Best regards,

Hello,

Yes, echoing a *written* frame on CAN is possible but only with the PCAN-Ethernet Gateway FD.

The PCAN-Ethernet Gateway CAN 2.0 version you have can only do something like an internal loopback (the frame is copied into the controller Rx fifo only, but is not written on the wire).

Hi,

If you're asking to get the so-called "hardware timestamp" from socket-CAN API, then the socket application has to set the corresponding socket option, something like:

int flags = SOF_TIMESTAMPING_SOFTWARE |
SOF_TIMESTAMPING_RX_SOFTWARE |
SOF_TIMESTAMPING_RAW_HARDWARE;
setsockopt(s, SOL ...

Hello,

The site's web page obviously contains an error: it lacks the name of the destination file for storing the public key on the local system:

it should read :

$ wget -q http://www.peak-system.com/debian/peak-system-public-key.asc -O- | sudo tee /etc/apt/trusted.gpg.d/peak-system-public-key ...

Hi,

Nope, nothing as changed in socket-CAN meanwhile. But, as already said, the PCAN driver in netdev mode now gives the same hw timestamps that the mainline drivers do. It's just a question of consistency between PEAK-System drivers.

Hi Thomas,

The hardware timestamps provided by the netdev interface of the PCAN driver are actually the raw one which are read from the device, without any further processing next. This has been done in order to return back the same timestamps than those returned by the mainline socket CAN drivers ...

Hi,

As said, this old behavior is no more supported. On the other hand, if you'd like to get it back, and since the driver is open source, then you are able to change this by yourself. Please download (for ex) https://www.peak-system.com/fileadmin/media/linux/files/peak-linux-driver-8.10.2.tar.gz ...
