About EMIF sync fifo mode (with Glue logic)

Dear Sir,

I'm using Ti DM642 connecting to FPGA using EMIFA (CE2) and the EMIFA CE2 is configured as Sync FIFO mode with Glue.

I try to generate a back-to-back data transfer (burst mode) from Ti and how can I reach that by using the EDMA? I  try to put data in L2-SRAM

 and enable EDMA to move data out to EMIFA CE2, but I only see the data is transferring a word once? below is my edma setting,

ping is point to L2 SRAM and CE2_FPGA is the "EMIFA CE2"
