How to enable CAN on STM32F042F4P6 CubeMX?

[tdarlic]

I was searching for smaller and cheaper MCU with CAN network. I have chosen the STM32F042F4P6 trough CubeMX but now when I try to enable CAN in CubeMX I cannot because it's grayed. What am I doing wrong?

I found it.

You need to swap the pins under SYS: "Pins PA11/12 instead of pins PA9/10"
