Hello all,that was the important tip. Now it works on both CAN interfaces. Document RM0390 also says that CAN2 is only a slave and has no direct access to the SRAM. That was probably the reason why I could not write to the mailboxes.Many thanks to al...

I have also tried it with a CAN bus and a CAN analyser. Unfortunately with the same result.Now I have done the whole CAN initialisation on CAN1. On CAN1 my test software runs immediately. I can see in the debugger how the mailboxes are written with m...
