Hello Everyone,
I am trying to do a Peripheral Device Transfer ( a PDT write by programming the EDMA and EMIFA registers ) from a FIFO on a Virtex-5 FPGA to a DSK6416 SDRAM.
My question is, when I look at the EMIF out clock ( ECLKOUT) on the scope it DOES NOT look like a square wave but rather like a sinusoidal wave with a frequency of 125 MHz and amplitude is 1.6 V.
Isn't ECLKOUT supposed to look like a square wave. I also grounded pin 75 of J3 in the Peripheral Expansion Connector to GND.
Regards,
Varun
