Hi,

do you like to use the SocketCAN driver or do you want to use the chardev interface? If you want to use the SocketCAN interface, there is no need to install our peak-linux-driver on that system. The kernel already has the driver for the PCAN-USB available as module.

Hi,

please see the CAN trace specification for more details: https://www.peak-system.com/produktcd/P ... Format.pdf

Hi,

which driver version is used (cat /proc/pcan)? Which PCANBasic API? Please check that you read the queue until you will get a PCAN_ERROR_QRCVEMPTY back.

Hello,

which PEAK hardware are you using? Please post a picture of the device. Please also post the output of uname -a

Hi,

but these are two different settings, one with data bitrate (CAN FD), one without (CAN 2.0). So which settings are you using (CAN FD or CAN 2.0)? Next, the specific settings for the data bitrate are still not visible, only the one from the nominal bitrate.

Hi,

please also post the settings of the data bitrate settings which are used in PCAN-View.

Hi,

I think it is related to the used bitrate settings. Please set nominal and data bitrate exactly to the same settings which are working with PCAN-View. Use OFD_BITRATE, OFD_DBITRATE and OFD_BRPTSEGSJW flags to be able to use the same settings.

Hi,

is your CAN bus cable terminated on both ends? Which exact bitrate settings are used in your CAN FD system on the other side?

Hi, please see info in the PCANBasic help file, to understand how the filter mechanism is working, and why you will also see unwanted messages when opening a hugh 29bit range. The filter is working with a ACCcode and ACCmask register. If you open a range where all bits have to be set to "don't care"...
