    • STM32F746 Discovery demonstration loses graphics icons on rebuild

    Posted by JohnChambers on 2015-07-22 20:32

    I have rebuilt the STM32F7 discovery application by importing the project into Eclipse. However, most of the graphical icons are corrupt.

    Has anyone seen this? Does anyone know of a fix?

    Thanks

    Erm - yes thanks for that. (MODERATOR: This was supposed to refer to some spam answers to initial post that were since deleted)

    Anyone got a reply about the programming?

    Hello John,

    As I know STM32F746G-DISCO demonstration graphic content is stored within N25Q128A external flash memory.
    I think that your problem is that openocd cannot program this external flash memory.

    To do this you have to convert your elf file to hex, and program it using ST-Link Utility v3.7.0 available in http://www.st.com/web/en/catalog/tools/PF258168

    before you load the hex file you should select "N25Q128A_STM32F746G-DISCO" Nor Flash from Menu > External Loader > Add External Loader

    I had the same problem with my STM32F746G-DISCO and, applying your hint the icons re-appeared correctly on the LCD!
    Thanks

    Hello, all,

    I am an old hand at micros and have a lot of experience with Cortex-M, gcc and Eclipse though I am new to the STM32 toolchain.

    How are folks getting the DISCO board demo cube file to import into SW4STM32? I immediately get a compile error. Looks like the paths are not correct, or some such.

    Thanks!

    I hat solve this with adding the external memory loader into the stlink utility and did a entire erase of it, before i reload the hex by using the stlink-uility.

    Be warned, you need to use the latest st-link utillity and upgrade the JTAG who is embedded on the disco board.
