Dear all,

I was trying to listen an FM program according to the instructions on

But I couldn't  finish the following operation. The system reponded with " Permission denied" although I got the priority of root.

echo fast_attack > /sys/bus/iio/devices/iio:device1/in_voltage1_gain_control_mode 

Consequently,  I heard something like "peng peng " from the phone output of Zedboard after I used iio_fm_radio 89.9 which is one FM broadcast  frequency in Shanghai?
