I have done experiments on Tx & Rx DMA of ADI Pcore on ad9361.
However, we found that the DMA formats is not the same for Tx & Rx.
For Tx DMA 4bit LSB out of 16 is unused while 4bit MSB is unused on Rx DMA.
(the bus is 16-bit wide wile the active bits are 12.)
Are you aware of this behavior or this is weird to you?
