Re: [Discuss OpenCPI] AD9361 ADC/DAC Tests in OpenCPI v2.0

The ad9361_dac_sub worker is the part of the ad9361 support system that
deals with the two dac output channel data paths, and each channel has a
control port (no data) to dynamically turn it off and on.
Hence off0 and off1 are ports (without data) for that purpose.  Those
ports have clock inputs, meaning they accept the clock from whatever
they are connected to.
This error looks like the clock inputs are not connected in the config
assembly for some reason.

The on_off0 and on_off1 ports of the data_sink_qdac_ad9361_sub are
optional, per the XML, so they should not need to be connected.

I assume you are not connecting them.

Can you post that generated file?, along with the corresponding
-defs.vhd file?

Which (device) workers are you including in your platform configuration XML?
