Part Number:AM3352
I need to know if the am335x supports CAN-FD? I saw this post but it actually doesn't answer the question. I then have the same question for the AM437x.
Here's a snippet from the CAN-FD spec from Bosch... From what I can tell, the CAN peripheral has to understand the CAN FD frame format and also be able to switch bit rate after arbitration.
Bosch
CAN with Flexible Data-Rate
Specification
Version 1.0
(released April 17th, 2012)
CAN FD shares the physical layer, with the CAN protocol as defined in the BOSCH
CAN Specification 2.0. The frame format however, is different. There are two new control
bits in the CAN FD frame, the first enabling the new frame format with different data
length coding and the second optionally switching to a faster bit rate after the arbitration
is decided. New CRC polynomials are introduced to secure the longer CAN FD frames
with the same Hamming distance as in the proven CAN protocol.
The CAN FD frame format has been defined so that messages in CAN frame format
and in CAN FD frame format can coexist within the same network. The BOSCH CAN
Specification 2.0 remains valid without any modification as an independent, self-contained
CAN bus protocol specification. The coexistence is assured by the requirement,
that in order to be compatible with this CAN FD specification it is required that a
CAN FD implementation be compatible with this CAN FD specification as well as with
the BOSCH CAN Specification 2.0.
In order to be compatible with this CAN FD specification it is required that a CAN FD
implementation be compatible with this specification as well as with ISO 11898-1.
