Is it possible to programmatically put the FMCOMMS4 into 'RF RX -> RF TX' loopback, by using the /sys/bus/iio/devices... filesystem?
I have a FMCOMMS4, attached to a Zedboard. I have been working with the FMCOMMS4 programmatically by writing to and reading from the /sys/bus/iio/devices/... file system. Being able to quickly try configurations just from the shell has been great.
However, now I'd like to put the board into 'RF RX -> RF TX' loop back. With the bundled ADI IIO Oscilloscope app, this is available under the "FMCOMMs2/3/4/5 Advanced -> BIST -> Loopback" combo box. However, It doesn't appear that the peer functionality is available under the .../devices file system.
