Yes, there is an IO unit which normally reacts on that message
Likely, you have a problem with your clock setting, TX/RX routing or
cabeling (termination etc.).
I would suspect it is the clock setting, as we have also problems with
clock_nanosleep() running 4 times too fast. I assume then that the IPB
clock frequency is wrong ?
On a Rev. B you normally set the CAN system clock to 33MHz via kernel
configuration parameter. Is CAN TX/RX on PSC2?
How do you setup your CAN network for a test ? Which commands do you use
?
Your setup with rtcanconfig was OK, or what do you mean.
Do you have terminators on both ends of the cable?
Wolfgang.
