Access to external flash memory for graphics [MPC5645S]

I'm Working with MPC5645S and code warrior IDE 5.9.

I write a image to external flash memory, and then I try to use the "AHB address" to set the beginning address of layer data. (DCU.LAYER[6].CTRLDESCL3.R = 0x70000000)

However, the image is not read correctly, it seems that the MPC5645 is not fast enough to read the data . Should we active the DMA mode?

Please could you send an example code that use an external flash memory to save images?
