I am using OpenCPI v2.0.1 and trying to port over the FSK application. I have a system with two AD9361's on it. I have some patches which allow me to initialize both AD9361's since the current release doesn't do that properly. Once that is done, I am getting the following when running the application: Exception thrown: HDL Control Op Failed: worker data_src_qadc:c/afe1_adc0(20) op start(1) timed out performing control operation (no OCP response on the WCI) (0xc0de4203) I have the RX side of things hooked up to afe1 and the TX side of things hooked up to afe0. Are there any suggestions on how to debug something like this? The TX side of things seems to at least run without this issue. Thanks, Brian

Another data point here is that I set the assembly to just use the first AFE and it at least ran without a timeout. So it's probably something with multiple devices still being problematic.
