CAN HighLevel API - No signals on osci

Hi Guys,

I hope you are doing fine today. I have a question about CAN. So I tried the CAN example with low level API, which is working fine, even if I reroute the PINS from PTA6/7 -> PTB0/1. I can see all the send signals on osci. For sure PTB0/1 are without a CAN transceiver.

But If I try now the CAN high level API example, with configured PINS,PORT, CAN_43_FLEXCAN,..in S32DS. Code is generated without any error and project is also compiling and linking. But I cannot see any signals on the osci. Neither on PTA6/7 nor on PTB0/1.

In the attachement you can finde the example of the High Level API.

Thanks for any help in advance!

Hi,

seems you started CanController_0 which is configured for loopback mode in setting, so you get no signals on module pins (PTA6/7 or PTB0/1). CanController_1 is not set for loopback mode, but it is not started at all, so no transfer can be seen on its pins (PTC8/9).

Hi,

Loopback was one of the issues, the other was to connect another CAN-node on the bus to get the example working.
