Hi All,
I'm using this CAN hat (see link below pls.) with RPI, and I have strange issues - starting with overruns (solved via lowering the CAN speed) and ending with codesys instability, the communication freeze in some time (usually hours, sometimes minutes). Checked via candump, the line is without any communication after this error, rpi is not sending anything.

the codesyscontrol log looks like xml in the attachment, cut from /tmp/codesyscontrol.log looks like:
Any ideas?
Thanks,

Do you also use the I2C_master at the same time?
Hello,
this topic is quite old, no help needed anymore. If this was meant as help.
Have a nice day,
