DRA797: Does J6Entry's DCAN IP conform to ISO 16845-1:2016 [Conformance Test Plan link layer / PHY]?

Part Number: DRA797

Does the J6Entry's DCAN IP conform to ISO 16845-1:2016 [Conformance Test Plan link Layer / PHY]?

From https://www.iso.org, the "ISO 16845-1:2016 specified the conformance test plan for the CAN data link layer and the physical signaling as standardized in ISO 11898-1.  This includes the Classical CAN protocols as well as the CAN FD protocols".

I believe that the Jacinto6 family of devices licenses the Bosch IP; this may be a hint to conformance to ISO 16845-1:2016, but I can not confirm.

I checked the latest J6Entry Technical Reference Manual and found no reference to ISO 16845.

I checked the latest TI Android Test Plan for 6AM.1.3d and found no reference to ISO 16845 (as I suspected as this is too high level for data link layer and physical signaling...).

Can anyone in the community confirm this?

    Hi Jason,
    I'm not a DCAN expert, I just prepared the DCAN TRM chapter in the past.
    I'm thinking in two directions:
    1. DCAN IP integrated in J6 SoCs was version from year 2011. I don't think we can tell it supports a standard newer than that. DCAN spec says DCAN controller conforms to ISO 11898-1 Data Link Layer (first release from 2003)
    2. The document you mentioned involves CAN PHY, which is not integral part of SoC. I.e. you need to test the entire CAN node when performing the conformance test.
