DMA driver problem

Jump to solution

Hi all:

 

I'm learning DMA through http://www.wiki.xilinx.com/DMA+Drivers+-+Soft+IPs,my question is how to do this step:

 

After successful compiling and loading the Microblaze/Zynq on to the target, we see the driver probe succesful log as shown,

xilinx-dma 40400000.axidma: Probing xilinx axi dma engine

 

and this step:

 

Running the test client will display the message when test is successful,

dmatest: Started 1 threads using dma0chan0 dma0chan1
dma0chan0-dma0c: terminating after 5 tests, 0 failures (status 0)

 

Regards

Chenbing
