How MR-CANHUBK344 setup CAN parameters

Hello Expert,

https://www.nxp.com/design/design-center/development-boards-and-designs/automotive-development-platforms/s32k-mcu-platforms/s32k344-evaluation-board-for-mobile-robotics-with-100base-t1-and-six-canfd:MR-CANHUBK344

My customer is investigating MR-CANHUBK344. Can customer setup CAN parameters such as baud rate/sampling position/ID filter, etc by IEEE1722 ACF protocol? That is to say the link partner setup the CAN parameters by IEEE1722 ACF protocol.

Hi,

probably it would be possible, if ACF message will contain such data and user will implement/parse that.
A given MR_CANHUBK3_IEEE 1722 demo example just convert an IEEE 1722 ACF-CAN fame and send it over FlexCAN (and vice-versa). No setting of baud rate/ID filter, etc is implemented upon ACF message reception. FlexCAN init is done at application start and does not change.
