Unable to create iio buffer for TX DMAC

Hi,

 

What could be the reason that iio_device_create_buffer times out (errno 110)? I have setup a adi dmac in my PL in order to write to PL (tx) but I can not create a buffer for it. My interrupt line is connected and also correctly defined in the device tree but never triggers (when checking /proc/interrupts). Is there a specific setting for the DMA?

 

Thanks for your help in advance!
