[ABANDONED] QSPI custom flash loader

    Hello, all


    I have more simple question.

    How can I add my own QSPI flash loader to the JLink?

    Is where any gcc compatible code for it?
    Can I have a debug functionality from jlink?

    Hi Alexey,


    You can write the flashloader using a GCC compiler by using SEGGER Embedded Studio.
    Please note that in addition to UM08001, there is a wiki article featuring an example(STM32F2) regarding open flashloader: https://wiki.segger.com/Adding_Support_for_New_Devices

    I saw this article.

    Unfortunately the default example doesn't work, I think the issue is in the section names inside the elf file.

    Is it possible to have an example of correct ld file?

    Hi,


    I am sorry that the example project does not work for you.
    Could you please give me the details on the error which occurs?

    Does the flash loader build?
    If yes, what error is reported by the J-Link software when using it?

    In the example we have only 1 definition of "Flash device type".
    This is #define ONCHIP (1) // On-chip Flash Memory
    Can we use this define for an external QSPI flash?
    Do we need a different define?


    the field SectorStartAddr in the struct SECTOR_INFO is unclear for me.
    Is it possible to have some info about this address?
    what does it mean?

    Is it possible to have more than 1 source file in the project?

    I add 4 c source files and have the following error in the Release mode

    Building ‘Template_CortexM’ from solution ‘Template_CortexM’ in configuration ‘Release’
    Compiling ‘macronix.c’
