My CAN1 bus works without problems, as before only CAN2 and CAN3 are affected. Enclosed is a current excerpt from the status. Both CAN2 and CAN3 do not provide any new data at the moment, although both buses are still active. For me it is noticeable that currently CAN3 has more packets than interrupts. I have observed the same with CAN2, but never with CAN1. Greg D. had indicated that there was a problem with CAN2/CAN3 in the past where the buses went deaf after a while. Has the problem actually been fixed in the past or is this still the problem that remains unresolved? Is there any other information I could provide to help track down the problem?
