  • [Question] SDRAM is initialized and GUI_INIT () is called, the system hangs.

    Dear Segger Team.

    I am now porting STEMWIN to STM32F469BET.

    We are working with CubeMX and are currently referencing the sample code for STM32469I-Discovery.

    However,SDRAM is initialized and GUI_INIT () is called, the system hangs.

    Below is the code I wrote and I do not know why the PC values ​​are not getting any more here.

    Thank you for your help.


  • Hi,

    Not that much of information, so I got some questions.

    Can you write manually into the RAM?

    Where did you placed the GUI memory?

    Did you made sure that, if the GUI memory is placed into the external RAM, it doesn't get into conflict with the framebuffer?

    Do you get into the LCDConf.c (this is not part of the library, so it should be possible to set a breakpoint there)?

    Regards
    Sven
