EDMA3 - EMIFA used by DSP when Linux is running on ARM

$

first, I developed the edma3 and emifa part of my project without any running system on the arm core and it was working so far. But now, I started Linux (Angström) on the ARM and i cannot see any access to the EMIFA from the EDMA3 controller. I can see that the EDMA3 events are occur and the PaRAM-Sets are updated after each event, like as expected. The EDMA3 controller should transfer datas from the emifa to an internal buffer but i cannot see that the there is any access to the emifa interface.

when I point to the emifa CS5 adresses, the same I use in the PaRAM-Sets, from the CPU, then I will see the access.

Where is the problem? What needs to be configured in the DSP that the EDMA3 access the emifa?

thanks

christian
