External SDRAM Placement (Framebuffer, FrontendHeap) Thank you for reading.I'm developing a GUI application using TouchGFX on an STM32H750-based board with a 1024 x 768 display using double buffering.As the UI became more complex, the FrontendHeap instances exceeded 300KB, causing RAM_D1 region insufficiency. To solve this, I implemented the following:Placed FrontendHeap instances in external SDRAMHowever, when the bitmap cache was placed in external SDRAM, screen tearing occurred.My final solution was to allocate only the View instances that are members of FrontendHeap to external SDRAM.(View instances accounting for more than 80% of the total FrontendHeap instance size)The resulting SDRAM configuration is:Framebuffer[0]：Bank 0 (TEX=1, C/B/S=1/1/1)Framebuffer[1]：Bank 1 (TEX=1, C/B/S=1/1/1)FrontendHeap views：Bank 2 (TEX=1, C/B/S=1/1/0)Outer and inner Write-Back. Write and read allocate.Q1: For FrontendHeap views, I set Shareable to 0 since this area isn't accessed simultaneously by CPU and DMA/LTDC. Is this understanding correct? How do
