IntersectSphere is locked

[maartenbrock]

Hi,

I'm trying to rebuild the bitstream with Vivado 2014.2 WebPack, but I get an error stating that there is some locked IP in the system. This appears to be the IntersectSphere block. What is that? Why do we need that? Can I replace it with a simple AXI4-Stream Data FIFO?

I have the same problem. I created the same design from scratch but this time I cannot import the hardware description file to PetaLinux.

Hi,
IntersectSphere is a private core hw created with Vivado HLS in order to test the system. Obviously you don't need it, just replace IntersectSphere with anything that has a AXI4 Stream interface. If you want to test only the DMA you can connect MM2S and S2MM interfaces in loop.

Actually, I've already done it (I can generate bitstream). The problem occurs while importing .hdf (hardware description file) to PetaLinux. In my opinion, PetaLinux should have recognized the AXI DMA core and create the necessary drivers for Linux. What I get is as follows:

petalinux-config --get-hw-description -p ~/Desktop/PetaLinux/projects/test_dma/

Which version of PetaLinux do you use?

[abdullahyildiz]

Is it possible that missing constraints cause it?

[durellinux]

We used the linux kernel released by Xilinx at the time we made the project
available.
Unfortunately I do not have Xilinx tool with me now to test it with the
latest Xilinx release.

-Just to be sure I'm doing the right thing-

Did you just run this command?

petalinux-config --get-hw-description -p ~/Desktop/PetaLinux/projects/test_dma/

[abdullahyildiz]

I think I've found my mistake.

I thought that the connection automation could handle assigning the interrupts.

What I've done is to use IRQ_F2P port at the Zynq PS part to connect mm2s_introut and s2mm_introut to the interrupt controller by using Concat IP in the IP Catalog (See http://www.xilinx.com/support/answers/55703.html).

Now

petalinux-config --get-hw-description -p ~/Desktop/PetaLinux/projects/test_dma/

does not give any error.
