Part Number: DRA821U
Other Parts Discussed in Thread: DRA821, AM3352,

Hi Champs.

There're some questions about CAN-FD driver support as below.

Can DRA821 MCAN and AM3352 DCAN be linked or interloacked? I wonder if the dr821u CAN-FD DRIVER can work with the AM3352 DCAN.
Hope there is technical data to explain the difference between MCAN and DCAN.

Hi Jack,

Unlocking this thread.

Are you still looking for an answer to this question?

Both DCAN and MCAN can communicate as different CAN nodes communicating over classic CAN supported by both controllers.

Hi Karan

Thanks for your kind reply.

Can you please clarify if Any code change would be required for DRA821' CAN-FD driver to support Classic CAN mode?

As I understood from Customer, They want to use Classic-CAN mode with DRA821U MCAN driver to communicate with AM3352' DCAN node.

Regards,

Jack

No changes are required to DRA821 CAN driver (on RTOS or Linux) to support Classic CAN. The driver supports the MCAN IP which supports both CAN FD and classic CAN.
