Hello,

You will use CAN2 as CAN1 but you need to take care of the filter configuration especially the SlaveStartFilterBank and FilterBank for CAN2: read this article.

PS: there is no CAN1 + CAN2 example available in CubeF4.

But you need to do some tests and tell us what you found before asking questions.

Then better to attach your complete project. Sharing parts of code may hide some issues.
