msgdma - no transfer to SDRAM

Hi, 

I'm using a DE0-nano with freeRTOS to transfer data from an ADC to the RAM and from there via USB to the PC. The msgdma (Modular SGDMA Dispatcher & Write Matser) should write the ADC-data to the Ram with Streaming to Memory-Mapped Transfer Mode. But the ADC-data stored in the FIFO of the Write Master is never written to the RAM. Has anybody an idea what the problem is? 

In the attachments you can see my qsys configuration.
