Marc, Thanks for your quick response. I reverted to my old kernel/file system and did a simple test just to make sure there are no hardware problems, everything seems ok, and the single packet is received. But with the new configuration, no packet is received. I did the following command to set up the can:
/sbin/ip link set can0 type can bitrate 500000 And then I run my application, which listens for a message, and on my pc I send a single packet. Actually in ifconfig now it shows no packets received or transmitted and no errors, not sure what caused the errors before, but I can be certain that it is a software problem now.
