Microzed  DMA kernel module creation issues

ghalady

Hi,
  I am attempting to integrate a PL Memory (BRAM) to the Microzed and run a Linux DMA test on PS from DDR to BRAM and vice-versa.

Here is what I have had success so far:
  I followed the instructions on http://www.wiki.xilinx.com/Build+Device+Tree+Blob

I was successful in building the dtb for the new BSP (with the PL memory-map added) from the system.dts that the Xilinx SDK creates.
However, now I don't know how to proceed. Should I rebuild the Kernel? I guess not, as the whole intent with which I started out was to create a "Kernel Module" of the DMA linux driver and load just the kernel module and not re-build the image.
Would appreciate if I get inputs on how to either build the kernel image or kernel module with the .dtb that I have!

Thanks
Girish

    Have solved this issue, the DMA Driver need not be built, it is built in the git-linux source tree.  Could get the bitstream integrated and build the FSBL + bitstream + uBoot to create "boot.bin" using SDK and also create Linux uImage and device-tree.dtb.

    Issue now is in getting the dmatest to work on linux prompt "zynq" prompt.

    Would appreciate any inputs
