To build for the hardware target, enter the following commands to set up the target build directory:

cd <Path to the cloned repo>/Getting_Started/Vitis/example/zcu102
mkdir hw
cp xrt.ini hw
cp hw

Then, after changing into the target build directory, enter the following commands to build the host application and device binary:

$CXX -g -std=c++17 -Wall -O0 -fmessage-length=0 ../../src/host.cpp -o ./app.exe -I$SYSROOT/usr/include/xrt -LSYSROOT/usr/lib -lxrt_coreutil -pthread --sysroot=$SYSROOT
v++ -c --mode hls --platform xilinx_zcu102_base_202320_1 --config ./zcu102_hls.cfg --work_dir hw
v++ -l -t hw --platform xilinx_zcu102_base_202320_1 --config ../src/zcu102.cfg ./hw/vadd.xo -o ./hw/vadd.xclbin
cd hw
v++ -p -t hw --platform xilinx_zcu102_base_202320_1 --config ../../src/zcu102.cfg ./vadd.xclbin --package.out_dir ./package --package.rootfs ${ROOTFS}/rootfs.ext4 \
--package.sd_file ${ROOTFS}/Image --package.sd_file ./xrt.ini --package.sd_file ./app.exe --package.sd_file ./vadd.xclbin --package.sd_file ./

To target Hardware, the v++ -t option is set to hw and the emconfigutil command is not needed, as you will be running on an actual hardware platform rather than an emulated platform. All other options remain the same.

Building for hardware targets can take a couple of hours, or more significant time depending on the machine you are building on and its current workload.

After the build process completes, copy the sd_card directory to an SD card, and plug it into the platform and boot until you see the Linux prompt. At that point, enter the following commands to run the accelerated application on the Embedded Processor platform:

cd /run/media/mmcblk0p1

You should see the same TEST PASSED message indicating that the run completed successfully. If you look in the zcu102/hw folder you will see some of the files that were created during this build and run process. Refer to Targeting Software Emulation for a brief explanation of the different files.

Congratulations!! You have just completed your first run of a Vitis accelerated application on the ZCU102 card! There are additional Vitis-Tutorials to work through to learn additional details of the Vitis tools, and Vitis_Accel_Examples to use for examples of host application and kernel coding.
