Hello! I've a lot of trouble with the second CAN controller on a phytec minimodul with a C167CS. The first CAN Controller works fine, no problems. But when I try to use the second CAN controller, I got nothing on the pins. I tried port 4 (IPC = 0) and also on port 8. The direction for the ports is correct, but the pins seem to be dead (no signal on). When I test the portpins with digital I/O, the work correct. The CAN2 is enabled in SYSCON3. ISR for the 2nd CAN is implemented, 1 transmit message declared. Is there anything more to do? An special bit to set for the second controller? I tried DAVE, to see, if there's something more, but I didn't find anything, which helped me. Maybe someone has a hint or link for me ... Have a nice day! SVEN P.S.: I know the keil/infineon application note, but the all use only the first controller!
