My understanding is that the sample rate cannot be changed in ADI IIO Oscilloscope GUI, and one has first to generate a "profile".
I have used windows application "AD9371 Filter Wizzard V1.10" to generate a profile. See attached file.
Next (after copying the profile file from a windows machine to zynq /home/analog/Documents directory) I followed instructions here:
and issued a command:
root@analog:/sys/bus/iio/devices/iio:device3# cat /home/analog/Documents/profile122.txt > profile_config
cat: write error: bad address.
How do I load a profile in ADRV9371 2018_R1 using ADI IIO Oscilloscope?
