Hello,

We have an example at mcusw/mcal_drv/mcal/examples/Can/soc/j721e/mcu2_1 location .Please go through it.

Hi,

There is another question to ask, about how to configure the hardware of the can of the tda4vm main domain and the can of the mcu domain?

Examples to do Transceiver configuration , interrupt configuration ,setting up CAN Frame for main domain you can see

in mcusw/mcal_drv/mcal/examples/Can/soc/j721e/mcu2_1/CanApp_Startup.c

and for MCU domain you can see in mcusw/mcal_drv/mcal/examples/Can/soc/j721e/mcu1_0/CanApp_Startup.c

Hi,

If the main domain can and the mcu domain cant are used at the same time, is there an initialization sequence? Can each core use all can?

Hello,

MCU domain CAN and Main Domain CAN can be used at the same time. In MCU domain example , we have 2 MCU CAN and 1 Main domain CAN being Initialized . Different cores can use MCU and Main domain CAN but it requires interrupt routing which is also explained in above example. Please go through it.
