Schematic for PX2 & Aurix, in order to inhibit / disengage from CAN bus (Solved)

For an ASIL D design, we want the ability to inhibit all CAN bus connections of the PX2 in the event of a fault.

  1. Is the AURIX capable of inhibiting all CAN transceivers, to a recessive state? Can you share the register / pin or command to achieve this?

  2. Could we use the schematic for the PX2 AURIX, so that we can develop software using the current layout?

Thank you,

Dear Nick,

  1. Could you please refer to EB-DrivePX_Software_User_Guide_DPX2_P2379.pdf in DPX2-P2379-EB-V4.02.04_release.zip?
    And also refer to https://www.elektrobit.com/products/ecu/eb-tresos/functional-safety/
    I sent EB contact point via PM, please check this topic with the contact point.

  2. Could you please contact your NVIDIA representative? Thanks.

For future searchers:

Elektrobit does not have the PX2 schematic, although the provided demo application does have CLI commands for GPIO and I2C control. Given a schematic, the demo application could possibly inhibit the CAN transceivers.

I’m working on contacting my NVIDIA representative now.
