libiio Could not create RX buffer: Permission denied

Question

Hello, 
 I am trying to drive adrv9009 and ran into this issue 
 * Acquiring IIO context
* Acquiring ADRV9009 streaming devices
* Configuring ADRV9009 for streaming
* Acquiring ADRV9009 phy channel 0
 rf_bandwidth: 100000000
 sampling_frequency: 122880000
* Acquiring ADRV9009 TRX lo channel
* Initializing ADRV9009 IIO streaming channels
* Enabling IIO streaming channels
* Creating non-cyclic IIO buffers with 1 MiS
Could not create RX buffer: Permission denied
* Destroying buffers
* Disabling streaming channels
* Destroying context 
 Code is adrv9009 example.
