We want to change the reference HDL code given for zc706&AD_fmcomms5 to loopback the received data from Rx2 and transmit it to Tx1. for this i short the pin of ad9361
adc_data_i0[15:0] to dac_data_i0[15:0]
adc_data_q0[15:0] to dac_data_q0[15:0].
Will it work as a loopback from rx->tx. IF yes then how to generate SD card image for the updated HDL code.
