I am using MPC5643L controller with evaluation board.

The Application start to run correctly in DRUN mode and able to send a CAN message from the controller. Than it is in main loop.

However when a CAN message is sent to the controller the App goes to SAFE mode. It also happen when I get a Timer interrupt.

When the App transit from DRUN to SAFE mode The RGM-FES register value is:  0x4480

  • - F_FCCU_ARD
  • - F_FL_ECC_RCC

The value of RGM-DEC is: 0x000

Please advise how to find the root cause of this error and hoe to resolve this.
