Linux-CAN / SocketCAN user space applications
I am currently enhacing the open source socketCAN test port for the eclipse titan ttcn compiler with j1939 support. (TTCN is a protocol testing language used in the telecummunication industry...
This is a request for discussion for a j1939player, similar to canplayer, which can replay j1939 message. For now it is assumed that the output of j1939dump is similar to...
Hello, When setting high speed bitrate (such as 500000 or 1Mbps), the actual bitrate between the dut and the generator caps around 208000 bps. I don't understand why the canfdtest...
This is a follow-up of the issue #159 . When testing the priorities, I noticed, that for the priorities 0 and 1, the message occurs, that setting the priority is...
I have socketcan running at 500 baud and I am experiencing delays/lag in receiving the CAN messages. I am testing onboard a vehicle and when I turn the steering wheel...
I'm stuck with J1939 on Beaglebone. uname -a: Linux beaglebone 4.19.79-ti-r30 #1stretch SMP PREEMPT Mon Nov 4 20:48:10 UTC 2019 armv7l GNU/Linux Installed the last status of can-utils from this...
Hi, I was looking for a way of letting a userspace program bring up/down a socketcan interface with a given bitrate (other than `sudo ip link`). Rationale: `ip link` requires...
The function “[exit](http://pubs.opengroup.org/onlinepubs/9699919799/functions/exit.html "Terminate a process.")” does not belong to the list of [async-signal-safe functions](https://www.securecoding.cert.org/confluence/display/c/SIG30-C.+Call+only+asynchronous-safe+functions+within+signal+handlers "Call only asynchronous-safe functions within signal handlers."). I guess that a different program design will...
According to the Linux manpage signal(2) the function `signal` should not be used as its behaviour can vary across platforms. Currently glibc mimics the BSD behaviour which implicitly uses the...
I was utilizing the J1939 sockets recently and I noticed something that didn't align with my expectations. When I call `getsockname` on a bound J1939 socket, the `sockaddr_can` structure that...
