I have got some new Evaluation Boards for the MPC5748EVB and then I have tried to flash the program


The motherboard is of a new revision (rev D). The error was something like this: “can’t enter Background mode”


Than I have used the old mother board (rev C) with the new Controller. Now it was possible to flash but the program is not running.

The LED D1 MCU is flashed. I think the CPU is hanging.


The controller is of new stepping.

Old (working) CPU:                   PPC5748GSMMN6A 0N65H

New (not working) CPU:            PPC5748GMMN6A 1N81M


Could you give suggestion to solve the issue.
