2. Create a couple of text files for H2C and C2H with different content using the following
commands:
echo "PS DDR Test" > dma_test_input.txt
echo "XXXXXXXX" > dma_test_output.txt
3. Run the test.sh in root, with init as argument, to initialize the DMA related drivers.
4. Execute the test.sh script, with either mdt or rdt as argument, to launch the QDMA test
application for the Zynq UltraScale+ MPSoC or the Zynq UltraScale+ RFSoC.
5. When the xilinx-app prompt comes up, initialize the port with the command port_init
0 1 0 1024 4096 within the test application.
6. Using DMA, transfer the data from H2C with the command dma_to_device 0 1 <H2C
text file> <PS/PL DDR address offset> <H2C text file size> 0.
7. Confirm if the DMA transfer is successful. An example based on the example files in step 2 is
as follows:
dma_to_device 0 1 dma_test_input.txt 1073741824 13 0
The second test, again based on the files from step 2, is as follows:
dma_to_device 0 1 dma_test_output.txt 1073741824 13 0
8. Using DMA, transfer the data from C2H with the command dma_from_device 0 1 <C2H
text file> <PS/PL DDR address offset> <C2H text file size> 0.
9. Confirm if the DMA transfer is successful. The figure below is a capture of all the steps
described in this procedure.
10. Close the port with the command port_close 0, and then exit the QDMA test application
(press Ctrl + D).
The DDR test flow and results are shown in the following figure.
