Use of presume-ack and/or one-shot flags
Posted: Fri 2. Sep 2022, 17:01
Hello,
For testing a CAN device I am developping, I try to set the presume-ack and one-shot flags using the ip command. This is with a PCAN USB x6.
Starting from a state where the interface is down, here are my results:
Is it possible to use these flags on PCAN-USB x6 or are they really not supported?
The kernel is from Debian, maybe it is too old and we need a newer version?
Anything else I should check?
Thanks!
