DMA on GPIO

Is it possible for DMA to be used to transfer data from GPIO ? I have tried it and Transfer error flag is raised. I am using STM32F4 Discovery

Never Mind. Problems Solved.

I was using DMA1 to transfer from GPIOC to Memory, but I found out that DMA1 is not connected to AHB1 & 2 peripherals in stm32f4 while DMA2 is. So using DMA2 solves it.
