    Hi, I haven't had too much time to work on this project lately, but I just wanted to give an update. I have tried calling MPU_Config() before initializing the GUI but with no success. My implementation of MPU_Config can be found below: C Source Code…

    Thanks for the suggestions. After moving .GUI_RAM (where aMemory[] is stored) to internal SRAM and increasing GUI_NUMBYTES to 64kB, I get emWin to initialize and display some text on the display. It looks like accessing memory on my external SRAM seems…

    Hi MikeFlyersFan, Thank you for your reply. 1) My stack and heap are located on the internal SRAM (192 +4Kb) which matches the memory segment of the sample project which uses a similar microcontroller with the same memory segments/sizes (stm32f407 vs.…

    Hello, I apologize for the long delay. After configuring my project settings to match the emWin sample project for STM3240G_EVAL, I have a different issue which is also causing a hardfault. If I configure GUI_NUMBYTES to be any value greater than 1223…

    Hello, I made a custom board using the stm32f407 microcontroller, a 480x272 tft display with the SSD1963 controller, and an external sram chip IS61WV102416BLL. Without emWin, - I confirmed that I can display an image on the display - Write and read back…
