Targeting Hardware - 2023.2 English

You can easily build for hardware by following the steps below.

Note: Because you already compiled the AI Engine graph and PL kernels for hardware emulation in the previous step, you do not need to re-compile them again for targeting the hardware. However, re-link and re-package for hardware run.

1. Link AI Engine and PL kernels with the platform:

   make xsa TARGET=hw
   

   or

   v++ -l --platform $PLATFORM_REPO_PATHS/vck190_custom.xpfm s2mm.xo mm2s.xo libadf.a -t hw --save-temps -g --config system.cfg -o   tutorial.xsa
   

2. Re-run the packaging step with:

   make package TARGET=hw
   

   or

   cd ./sw
   v++ --package -t hw \
      -f $PLATFORM_REPO_PATHS/vck190_custom.xpfm \
      --package.rootfs=$ROOTFS \
      --package.image_format=ext4 \
      --package.boot_mode=sd \
      --package.kernel_image=$IMAGE \
      --package.defer_aie_run \
      --package.sd_file host.exe ../tutorial.xsa ../libadf.a
   cd ..
   

   When you run on hardware, ensure that you have a supported SD card. Format the SD card with the sw/sd_card.img file. Then plug the SD card into the board and power it up.

3. When a Linux prompt appears, run the following commands:

   dmesg -n 4 && echo "Hide DRM messages..."
   cd /run/media/*1
   export XILINX_XRT=/usr
   ./host.exe a.xclbin
   

   You should see TEST PASSED. You have successfully run your design on hardware.
