I'm create project zcu102_2019 by BSP file from that lnk and i'm get recipe file follow step from DPU-Integration 

After build project, I'm try to check dpu and version dnndk

You can try install the dpcma.ko manually on your target side.

Find the dpcma.ko driver in the following path after you install the AI SDK on your host.

That's a problem...

The best way to solve this problem is to recompile the dpcma driver with the dpcma source code. However, as far as I know, the driver is not yet open source. You can contact Xilinx FAE for help.

The other way is to change your kernel number to be the same with the dpcma driver. 4.19.0+
