I am developing serial boot for MPC 5644a.
The thing is that i can not read echo from mpc 5644a when i gave a echo command (id= 0x01 with 8 bytes password).
The EVB I am using is xPC56xx EVB which is xPC564AADPT with XPC56xx EVB motherboard.
The jump J7 for boot mode set to serial mode already, but the CAN message always shows error frame.
Is there any setting i need to consider?
