    Quote from SEGGER - Nino: “For SDRAM inits we recommend using a JLinkScript. The JLinkScript API is explained in the J-Link user manual UM08001. ” Do you mean, use JLINK_MEM_WriteUxx() functions in the script to program registers of MCU such way…

    Thread
    I have a board with LPC1785 MCU and an external SDRAM. At MCU reset the SDRAM isn't configured so it isn't mapped to the system memory. I'd like to know if Ozone can be configured to program internal Flash memory and external SDRAM at debug startup.…

    Replied to the thread Bitmaps saved in SDRAM.

    Post
    I found a solution. I changed linker script to put emWin constants used in GUI_BITMAP structures (GUI_BitmapMethods*) in a fixed location. In this way, even if I change the application code, GUI_BitmapMethods* are always at the same address and…

    Thread
    The application code is in the internal Flash memory of MCU (LPC1785). I need to save constant bitmap images in the external SPI Flash memory. At startup I copy the images from SPI Flash to SDRAM, so the access is much more faster. I have plenty of SDRAM…
