Can't create profile_config with AD9371 IIO device driver

AD9371 uses profiles to designate different device configuration settings for the Tx/Rx/ORx/SnRx channels. Using IIO device driver to load a profile by simply command line "root@analog:/sys/bus/iio/devices/iio:device3# cat /usr/local/mykonos/profiles/lte20.txt > profile_config" is demonstrated in the WIKI page AD9371, AD9375 highly integrated, wideband RF transceiver Linux device driver [Analog Devices Wiki] . However, I got a failure response "can't create profile_config: Permission denied" in my experiment with ADI AD9371 transceiver evaluation board. What's the possible reason for this failure? Any clue will be highly appreciated!
