We are trying to get VDMA to work on Zynq MP under Petalinux (version 2018.2). We use a driver we found on github: https://github.com/bperez77/xilinx_axidma
As a first test we are trying to get VDMA work in loopback mode.
When we make a VDMA transfer, only every fourth 32-bit word gets transfered (bytes 0-3, 16-19, etc.). The other 32-bit words in the destination buffer keep their original values.
Does anybody have an idea what could be wrong?
Here is how the VDMA IP-block is configured:
