Hi NXP Team,


In one of the hardware designs we are planning to establish a communication link between two IMX8MQ processors. For that we are planning to use the PCIe as the communication medium. The reason we are trying to establish a connection using PCIe is to save the PHY space in the circuit.


On the hardware front, we are planning to establish communication using as per the below diagram.

  1. Can you please help to verify the hardware connections and check whether this design is feasible or not from the standard point of view? 
  2. Can we get some software reference for this method? (I have already searched the queries in this forum but not able to find the same?
