Hi :

      There are only two can in the MCU domain,but we need three can ，We want to use the can resource of the main domain in the mcu，Is there any guidance on how to use it

    Hello,

    The CAN modules in the main domain are accessible from the MCU domain. The registers are available and accessible from the MCU domain. There are instances when modules are not accessible from the MCU domain, such as when firewalls are enabled that would block the access, or when memory protection is in place.

    We have an example in our MCUSW (AUTOSAR MCAL) drivers where we use various can modules with the MCU R5:

    Another consideration is the need to do interrupt routing as the interrupts from the modules are not directly tied to the MCU R5 core.

    Regards,
