Hi，TI

I am using ti-processor-sdk-linux-rt-am62xx-evm-08.03.00.19.

I can't see the device node of mcu mcan in the dtsi of the current sdk?

Does it mean that the current sdk linux does not support mcu mcan? Users can only develop through the mcu sdk?

Hi,

Thanks for your reply.

Does TI have plans to support mcu mcan on sdk linux?

No, there is no plan to support the MCU MCAN in Linux.

The MCU MCAN interrupts are not routed to the MAIN domain, so the Linux driver would have to use polling mode to handle MCAN, which won't be efficient.
