First steps

This project implements Nyuzi on a Xilinx Ultrascale+ ZCU102. Please refer to doc/Documentation.pdf for a project documentation.

The following steps are required to to build and use the software/hardware:

  1. Clone this repository if not already done

  2. Get Nyuzis Toolchain by executing the following command in the root directory

     git submodule update --init --recursive

  3. Read the build instructions for Nyuzis Toolchain and build it

  4. Build Nyuzi by executing make in the subdirectory sw/nyuzi_sw/

  5. Get the bare-metal application executed by Nyuzi. You can choose between two files:

    1. Use sw/nyuzi_sw/software/apps/rotozoom/bin/rotozoom.bin as a very simple example. Executing this file doesn't require any resource file as everything (program code and resource data) is included within one file. If you start this file, some rotating smilies should appear on you screen and Nyuzi starts to send the current FPS via UART to your host PC.
    2. Use sw/nyuzi_sw/software/apps/scene_viewer/bin/scenev.bin if you want to load different objects and rotate them.

  6. If you want to use the more functional scene_viewer application, you have to copy some scenes to the SD card too. Use the binary files from ../apps/cup, ../apps/pinocchio, ../apps/pyramide and ../apps/luigi_circuit.

Xilinx's SD card library doesn't support long filenames. It is recommended to use short names like pino.bin, pyra.bin and so on.

  1. Get the hardware bitstream file

    1. This repo provides an already generated bitstream file ready to use. It is stored under the path syn/ZCU102_BD/GPU_BD_wrapper.bit.
    2. You can create a new one by opening the Vivado project syn/ZCU102_BD/Vivado/Nyuzi_BD.xpr. It is strongly suggested to use Vivado 2017.4!

  2. Get the software running on the ARM Cortex processor. You can find it under the path sw/zcu102/scene_change/src/. It's purpose is to list all files stored on the SD card via UART. Using the board pushbuttons, you can select a program file (point 5) and a resource file (point 6), specify the formats (binary or ASCII) and load it to the correct memory location. Nyuzi is released by pressing the middle push button.

  3. Get a PMOD VGA adapter and refer to syn/ZCU102_BD/pinning/pinning.xdc for a description how the pins must be connected.

  4. Connect UART and JTAG cables, insert the SD card to the board, start XSDK, program the PL with the bitstream (point 7) and execute the software for the ARM processor (point 8).

  5. If you choose the scene_viewer application for Nyuzi, control the rotation with the pushbuttons.

In addition to rotating the objects, you can move within the scene. This is only useful when loading luigi_circuit. To do so, set at least one switch to on which changes the behavior of the pushbuttons.
