  • Greetings,

    We do not advise you to downgrade your firmware. It can potentially brick your cyclone.

    What we can do instead is help you in making it faster again. Could you tell me which chip you are trying to program and what kind of commands you are running your programming image?

    • the chip is S912XET256 and the commands are

      CM X:\Freescale_9S12XET256_1x16x128k_256k_Linear_Pflash_PLL.12P
      SS X:\Flash.s19
      EN ;Erase if not Blank
      BM ;Blank Check Module
      PM ;Program Module
      VM ;Verify Module
      VC ;Verify Checksum

      but the version 8.52 it's slower

  • Greetings,

    I would recommend to update your cyclone to version 8.63. Maybe it is faster than 8.52 for your setup:

    Let me know if it makes a difference.
    Also, I would recommend removing "BM; Blank check module" after a erase since it will always pass. And I would also recommend choosing either VM or VC, but not both. I know that this is the default setup from the image wizard, but it is bulky and slow.

  • Greetings,

    Have you gotten a chance to firmware update your Cyclone and see if it improves?

    • Hello!

      Sorry, for too late.
      I just to firmware update my Cyclone but It doesn't improve.
      The time for verifying is too longer than the Cyclone with firmware 8.44
      is there a tool to backward of version??

  • Greetings,

    Did the latest firmware work?


    Takao Yamada

    • Hello

      Johnny helped me with the firmware.
      the last firmware doesnt work.

  • Greetings,

    I suggest creating a support request ticket by going to Support Page -> Support requests. We may ask you for schematics and the board to be sent to us for evaluation.

  • Thanks but, I could downgrade my firmware with help Johnny.
    Because He couldn't see the the time difference between the firmware versions
