OMAPL138 arm emifa

Hello,

I am using OMAPL138 custom board.I can use the emifa(CS5) as extend IO on dsp side successfully.

I used dsplink to load the dsp application on the arm side,and initilialized the emifa on the DSP side.

It was OK to read write emifa on the dsp side.

when I write the emifa on the ARM side(Linux),the linux application collapsed. 

 My question is whether  I can  use emifa on both DSP and ARM side.

Thanks in advance.
