Standalone PL330 DMA transfer test

Follw 's work at http://forums.xilinx.com/t5/Embedded-Linux/PL330-DMAC-Test-Code/m-p/491154 and the dmatest.c in zynq linux 2014.1, I am now trying to enable the data transfer not through usespace sysfs.

 

The idea is to create a sysfs handle as a trigger that start or stop the DMA for specified source and destination address. I come front the fill_queue error while I cannot find out the reason. Could any expert help?

 

Thanks. 

 

I attached the code.
