TDA4VM: TDA4VH - MCU_MCAN0/1

Hello,

1. I wonder what is the difference between MCU_MCAN and MAIN_MCAN.

There is no difference between these MCAN modules. They are the same module, but in different domains. Our MCAN modules in our SoC are the same across devices, you can see more information about our MCAN module in the TRM:

What is the relationship between MCU_MCAN and MCAL CAN of MCUSW?

The MCU_MCAN is the CAN module in our SoC. The MCAL CAN of MCUSW is the software driver that can be used to control this CAN module. The MCAL driver is conformant with the AUTOSAR standard v4.3.1.

Haeyeon Song said:

    How can the Linux MCAN driver control it?  s it calling the API of MCUSW's library or sending and receiving messages between those ?

The Linux MCAN driver is separate from the MCUSW driver. The Linux driver can control the CAN modules as well independently of the MCUSW driver.

3. If you have a manual/datasheet for reference, please share any.

The TRM has information about the MCAN module, see Chapter 12, Section 4.4: https://www.ti.com/lit/zip/spruil1

The MCUSW has documentation about the MCAL CAN Driver: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/mcusw/mcal_drv/docs/drv_docs/ug_can_top.html

Please let me know if you have further questions.

Thanks,

Erick

Thank you

I will ask it later if necessary~!
