While using Zynq SDR, the capture length can not exceed '16777216'.
I want to capture length longer than the prescribed. I get the following error.
Error using comm.libiio.AD9361.rx/capture
Requested capture length (23592960 Samples) exceeds maximum value for this number of channels
(16777216 Samples). Use 'EnableOversizeCapture' to risk compromising data contiguity in return for a
larger capture length.
How to use 'EnableOversizeCapture in order to capture longer length than the one prescribed.

You can just enable the property'EnableOversizeCapture' by setting it to true.In addition to the other arguments of capture function,specify it as a name -value pair.

I have another question related to the above issue.
When I tried to transfer rather large size, I get the following error.
Generating WLAN transmit waveform:
Error using comm.libiio.AD9361.tx/validateInputsImpl
The maximum samples per frame for the selected channel mapping is 16777216.
Error in comm.libiio.AD9361.tx/transmitRepeat
Error in OFDM_SIM1 (line 189)
How do I overcome the above error? It seems to me that I can not have the samples per frame more than 16777216.
