TFT LCD with FSMC and External RAM

Hi all,
I'm working on a project with a dumb TFT LCD (320 x 240). I'm trying to display static images (no double buffer). I've been able to display images (in 565 format) that I load on the flash memory and refresh it on the display using DMA and FSMC. I'm now trying to refresh the same images from external RAM using DMA again but I don't seem to get it right. What I'm doing is copying the images from the flash to the external RAM using DMA and then refresh from the external RAM.
I thought maybe I wasn't writing to external RAM, I tried to view what's inside the external RAM after writing and I was able to see the same data that is on flash.
I based my approach on the AN3241.
Can you guys please help me to see what I'm doing wrong.
Thank you
