I'm working with the ZCU102 platform and the FMCOMMS2 board. On the PL side, I used the [hdl_2022_r2/fmcomms2/zcu102 project](github.com/.../zcu102) from GitHub, and on the PS side, I directly compiled the [2022_R2/no-OS/ad9361 project]( github.com/.../ad9361).
My goal was to send and receive data via DMA on the PS side. To do this, I created a fixed set of data and wrote it to the DMA. In the block design on the PL side, I placed an ILA at the input and output of the AD9361 block. When I enabled the “loopback” mode shown in the AD9361 block diagram, I was able to verify that the data I sent matched the data I received back.
However, after disabling loopback mode and connecting the Tx and Rx RF ports to each other with an antenna cable, I expected to see the transmitted data echoed back. Instead, I observed a continuously increasing or decreasing series of numbers in the ILA. This issue occurred even though I made no changes to the reference project. I would be very grateful for any guidance on how I might resolve this.
