  • WM_SetCreateFlags(WM_CF_MEMDEV) caused hard Fault after minutes

    Hello,

    I need a help. I have application based on STM32F429BI and everythink work stable without WM_SetCreateFlags(WM_CF_MEMDEV). I wanted to avoid flickering and put WM_SetCreateFlags(WM_CF_MEMDEV).
    After 30-60 sec program generated Hard Fault. Can you help me? I even started checking electrical connection with SDRAM but SDRAM works fine.


    I have GUI_BUFFER 150kB. Without active MemmoryDevice all Windows and peripherials work ok.


    regards,
    Piotr

  • Hello Piotr,

    Have you tried to increase the 'GUI_BUFFER'?

    Using memory device increases the amount of memory required by emWin.

    Which version of emWin are you using?
