Staff: Johnny N.

  • we can't download the boot-load to MPC555LFCZP40 use the CYCLONE-MAX programmer in circuit .
    we can connect to the mpc555LFCZP40 and upload the original FW,But can't erase it and programming new one.
    Could you help advise how to fix this issue? Thank you!


    • Is the flash internal or external?

      Which algorithm are you using?

      What happens when you try to erase?

      • Hello Johnny,
        Thank you reply.
        After applier 5v voltage at VPP that I can erase and download the FW to the MPC55. But it can't bootup after finish the FW download. Could you help advise?
        The FW inculde bootload,it is bin file.we use the PE's tools of BIN2S19 to cover to s19 formart,and start address from 0.
        1.flash internal
        2.USE "Freescale_mpc555_1x32x112k_CMF_448K_revk3_alg61.PCB"

        Kindly looking forward to your reply. Thank you!

        • Can you get a board that does boot and perform an upload module from it? This will dump all the contents of flash to an S19 file.

          Then you can use that S19 and try a verify module against the programmed boards that do not boot. This will tell you what the differences are.
