CAN Bus doesn't work

heiko g

Hello,

i have a problem. I can not make the can-bus working.

I tried a lot of code, and checked it again and again. In the startupfile (start167.a66) i, configured the X-Bus and the CAN-Bus. But it doesn't work.

The Busstate is dominant or recesive, depending of the state of the port (why can i change the pin-state?).

I think it is interessting, that the simulator gives me SYSCON = 0x0004 (that is, what i expect). When i watch the Adress of SYSCON in the debug-window when debugging the micro, there is constäntly 10 00 (SYSCON=0x0010).

I have terminated the bus with 120Ohms, a Phytec-Minimodul and CANoe.

Any advices, what i could check again???

Thanks.
