I am using the fmcomms1 evaluation board and kintex 7 kc705. In the reference design, the ip 'sys-wfifo' has 32-bits m_wdata. I want to write 64 bits to ddr and then read them from ddr by
adc_capture(fmcSel, 200000, DDR_BASEADDR);
What should I modify for hdl code and SDK code?
e.g. (axi_ad9643_dma ip and 'adc_capture' in SDK ?)
