Hi. I'm debugging this on my own but decided to ask the experts here to accelerate the effort. I need to do RX1 to TX2 RF loopback on the FMCOMMS3/ZC702 platform. The only thing I've tried so far is adding "adi,tx_channel_swap_enable" line to the device tree. I am not sure if it's supposed to help, and it didn't actually. Is there a way to do such a loopback?
