  • [SOLVED] Flash Loader Failure when external flash is accessed

    Hi,
    I'm using j-link in order to program my STM32H743 device via IAR IDE.
    I'm using extened ex-flash (winbond W25Q128JV) with QSPI interface.
    In my code, I defined an image with an address on the external flash.
    __root const unsigned char _acImage_01_16bit565[109512UL+ 1] [b]@ 0x90000000[/b]

    When I try to program the device I get the following error window (see attached).
    Tue Aug 27, 2019 12:53:14: Flash download warning: 109513 out of 109513 bytes from data record CODE:[0x90000000,0x9001ABC8] will not be flashed
    Tue Aug 27, 2019 12:53:14: There were warnings while generating flash loader input.

    Do you have any suggestions for programming the device (including the external flash)? I checked the J-Flash tool, but I could not program it right.
    If I need to create my own flash loader can you please advice on how to do it?

    Thanks

  • Hello,

    Thank you for your inquiry.
    For the STM32H743 external QSPI Flash is currently not supported.
    segger.com/downloads/supported-devices.php

    But you can add support yourself by using our open Flash loader interface.
    wiki.segger.com/Open_Flashloader
    Alternatively we can do it for your, in that case NREs would apply.
    Would that generally be of interest for you?

    Best regards,
    Nino

    For opening and supporting a new device, I need a flash loader, which flash loader can I use?
    STMF7 flash loader would match?
    STM32F7 is not compatible to STM32H7. You would need to write a new Flash loader as explained in the Wiki. Or we can do it for your for NREs.
