FCAN Rx FIFO Example for MPC5777C?

ranulf — Fri, 15 Jan 2021 16:01:37 GMT

Windows 10, R2020a, NXP_MBDToolbox_MPC57xx version 3.2.0, X-RDVCU5775EVM which has the MPC5775B chiip.

I have a setup with a lot of CAN traffic. Up until now I have used the FCAN blocks without Rx FIFO enabled. However, many messages are getting dropped, probably in situations where multiple CAN messages arrive in the same Simulink timestep. This is a situation where FCAN with Rx FIFO is essential.

I can't find any examples that demonstrate the use of FCAN with Rx FIFO and the NXP_MBDToolbox_MPC57xx. Can someone please create one? Thanks.

For a first try, I created a very simple Simulink model that attempts to utilize FCAN with Rx FIFO on. When I attempted to build an error was raised.

I have attached the model and the message created during the build attempt.

Hi @ranulf

Did you manage to solve this issue? I am currently trying to do a similar thing and am struggling.
