grodansparadis / vscpl2drv-socketcan Goto Github PK

Hi,

I'm trying to setup this driver, but I'm unable to make it work.

I'm using a Raspberry Pi3 B+ with Raspbian (Buster) and the armhf VSCP package. (https://github.com/grodansparadis/vscp/releases/tag/v14.0.4)
This system is a clean/new install and updated to the latest version.

As interface, I'm using a usb_8dev USB interface, initialized using the script included.
The can0 interface is up and the "candump"-command displays all VSCP events on the bus.

I've compiled this driver from source. (I needed to manually add "-lexpat" to the "LIBS" environment variable to make it compile.)

The config format as decribed in the README didn't work for me and the driver would not be loaded.
I ended up using the config format as in the provided example of vscpd, which seems to successfully load the driver:

<!-- Level II socketcan --> <driver enable="true" name="USB-CAN|" path-driver="/var/lib/vscp/drivers/level2/vscpl2drv-socketcan.so" path-config="/var/lib/vscp/vscpd/socketcan.conf" guid="00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00" />

The '|'-character in the driver name is as indicated on https://github.com/grodansparadis/vscpworks to get an older version of vscpworks (13.1.0.10 Aluminium) on Windows working with a 14+ version of the daemon.

However, I'm unsure of what should be in the file referenced by "path-config" as there is no example available.
I currently have a file which only contains the name of the can interface "can0". Is this correct?

The "USB-CAN|"-interface is visible in VSCPworks, but it seems no events are visible and scanning for devices doesn't work.

"journalctl -ex" gives me an error which I don't know what is means: "USB-CAN|: Unable to get dl entry for VSCPWrite."
