Frame Buffer is allocated in both RAM and Flash I'm working with a system built around the STM32F767 which has 512kB of internal RAM, and 2MB internal Flash. There is no external RAM or Flash, so the entire application has to live within those resources. We are using RBG565 format with a 480x272 LTDC, and a single framebuffer of 255kB. Since both all the code and all the graphic images must fit into the 2M Flash, we must be quite careful to ensure that we remain within these limits. In general, a full-screen image will require app. 255kB of Flash. We're using TouchGFX Designer 4.17.0, STM32CubeIDE 1.7.0, and TouchGFX Generator 4.17.0.In the STM32CubeMX editor, a single buffer scheme is selected:In the resulting generated code, the frame buffer is declared in TouchGFXGeneratedHAL.cpp:namespace
{
// Use the section "TouchGFX_Framebuffer" in the linker to specify the placement of the buffer
LOCATION_PRAGMA("TouchGFX_Framebuffer")
uint32_t frameBuf[(480 * 272 * 2 + 3) / 4] LOCATION_ATTRIBUTE("TouchGFX_Framebuffer");
static uint16_t
