Generate Vitis Platform
Follow this tutorial to generate the Vitis Platform for VPK180. There are a couple of changes:
- Step 1-3: Select VPK180 as the device. Generate 3 clocks: 100MHz, 200MHz, 300MHz.
- Step 2-2: git-branch should be
xlnx_rel_v2023.2.system-user.dtsiis on Vitis Tutorial Github Repo. Change the name to Xilinx custom-vpk180. Board name isversal-vpk180-reva.
Launch V++ Script for P&R
After exporting the xo container, replace the platform path, xo path, and constraint path in generate_bitstream_sample.sh and launch the script to start P&R.
Hardware Emulation Using QEMU
After exporting the xo container, replace the platform path, xo path, and constraint path in generate_bitstream_sample.sh. Change target to hw_emu and turn on debug mode -g. After generating the xsa file for hardware emulation, run package_sample.sh with the same modifications as generate_bitstream_sample.sh, with the files you want to include in the SD card image (including the host binary, launch scripts, and configuration file xrt.ini). You will find a script /package/launch_hw_emu.sh to start QEMU directly.
