EDMA on OMAPL138 in FIFO Mode

Hi Team,

We are using external ISP1763 USB as Peripheral device connected to OMAPL138  over EMIF and uses the CS2

The ISP1763 Address/Data bus width is 16bit width

Presently we are working on PIO mode it works perfectly with out issues, but we are achieving very less through-put(bandwidth) of 22Mbps

We are trying to configured the EDMA for data transfer/receive but it doesnt works

Can you please helps on Re-Solving the EDMA issue to increase the throughput

1/ Is there any changes required to configure the EMIF & CS2 register settings to increase throughput

2/ We configured the EDMA as per the below

SOURCE_ADDRESS = SDRAM, 16bit

DESTINATION_ADDRESS = FIFO, 16bit

NOTE: Can EDMA be configured in CONSTANT Addressing Mode for FIFO access

If it can configured please if any example code is available to configure EDMA in Constant Addressing Mode

Thanks
