Partial Reconfiguration for the Zedboard

Former Member

Hi Forum,

I was wondering if anyone has managed to complete a partial reconfiguration (PR) project with the zedboard, specifically having the PL completely reprogrammed with the PS and a stand-alone OS.

So far I have managed to generate full and partial bitfiles and program the board just using impact. I fall on my face, however, when I attempt to code something in the Stand alone OS through SDK. To test I convert the partial bitfiles into bin files and use the XMD to store it in the DDR. I then found some code regarding the Zynq on the Xilinx forums for programming the fabric with the stored bin file.

Has anyone successfully managed to do this?

Thanks

    Hi all !! I'm beginner with Zedboard and trying to test partial reconfiguration function on the Zedboard. My design for testing is very easy.
    - I designed counter and use the button to control the counter. Every time hitting the button, counter will increase 1 or decrease 1.
    - The counter module is the partial reconfigurable module with function count up and count down. In my design i just used PL for partial reconfiguration and Impact to download the bitstream (no PS).
    I built the PlanAhead project and generate the full bit stream and partial bit stream for the counter module. when I downloaded (by Impact) the full bit stream of count up module it works ok but when i try to download the partial bit stream to change the counter function from count up to count down, the function doesn't change. Or when i downloaded the full bit stream for count down, the counter doesn't change either, it still counts up. I try to with many configuration options (imported, implemented, promoted) but it still doesn't change from count up to count down.
    My questions are:
    1. Can i check the partial reconfiguration function on this way.
    2. What issues in may design or i misunderstood something in partial reconfiguration function.
    Please give me your suggestion. i appreciate your help a lot.
