Unexpected data corruption when camera and display both running (with SDRAM framebuffers in between) Apologies in advance, this is a long one.We are developing a camera application on an STM32H747. We have 32GB of SDRAM configured through FMC.We have a NanEyeC camera from which we are continuously acquiring data in packed bayered format via SPI, into one of three SDRAM framebuffers [A1,A2,A3] (a three-buffer system so that one is reading, one is pending, and one is writing).On our main loop we check to see if one of the raw camera data [A1,A2,A3] has available data and then (1) unpack and debayer it into a 320x320 RGB888 SDRAM framebuffer [B] (we want this intermediate point from which the user can save images), then runs a scaling operation to transfer it into a 460x460 (our display size) RGB888 SDRAM framebuffer [C],After these for loops we start a DMA2D transfer which combines [C] with overlay graphics in 460x460 ARGB4444 SDRAM framebuffer [D], and outputs the result into 460x460 RGB888 SDRAM framebuffer [E], and the DMA2D end-of-transfe
