Introduction

Is the LCD DMA a gather scatter DMA ? Where is it located exactly ?

NXP_Support's picture

The LCD DMA keeps the LCD FIFO full. It can only DMA from the LCD framebuffer which must be a contiguous block of memory. Scatter-gather support isn't provided, but due to the nature of how the frame buffer must be arranged (in physical memory), scatter-gather support isn't really needed.
