Infineons C166 is delivered in version (step) FA since a while instead of the old step BA. Last week I got new boards with that chip. Now I have problems with the CAN-Bus. Either the bus doesn't work at all or at some of the boards the can-bus is receiving and transmitting but my old hardware seems to have problems with the new telegrams. Does anybody have similar problems? Any solutions? Infineon denies any changes at the can-section of the controller. Bye Leo
