freescale 5554 processor flash

  • We were trying to flash a freescale 5554 processor. We have used P&E Micro ICD software.

    We have selected Freescale_MPC5554_1x32x256_Shadow_Blk_Freescale_H7F_32_Driver.PCP file as the algorithm.

    There was the following warning when we tried to erase –

    ERASE_CONFIRMATION=WARNING : ALL SHADOW BLOCK DATA WILL BE ERASED! You must reprogram the censorship information prior to reseting the device otherwise you will permanently censor (secure) the device. Do you wish to continue



    I continued.
    After this we are unable to connect to the target.

    We get the error which says – Can not enter background mode



    Please let us know if there is any way to recover from this.

  • Hello Pavan,

    Unfortunately, MPC5554 device architecture does not allow one to recover from securing a device. Once device is secured, it is permanent. In order to continue your development you either have to replace a chip on this board, or get a new evaluation board.

    Best Regards,
