ultra96-fractal
===============

This is an Hardware-accelerated [Julia set][julia set] explorer running on [Ultra96][ultra96]. The current implementation can generate 1920x1080 pixels image at 16 frames per seconds.

## Try it on your Ultra96

1. Download `ultra96v2.zip` from the [latest release page][latest release], extract the files (`BOOT.BIN`, `boot.scr`, `image.ub`), and copy these onto FAT32 formatted microSD card.
2. Insert the microSD card into the Ultra96 microSD card slot.
3. Connect the Ultra96 to a monitor.
4. (optional) Connect a gamepad (e.g. [Logitech Gamepad F310][f310]) to the Ultra96.
5. Connect the power supply to the Ultra96.
6. Press the power button.

## How to build

Required Tools:

- [Vivado Design Suite - HLx Editions][vivado] (2024.1)
- [PetaLinux Tools][petalinux] (2024.1)

1. Clone repository

$ git clone --recursive https://github.com/Tosainu/ultra96-fractal.git
        $ cd ultra96-fractal

2. Import Vivado project and generate Bitstream

$ vivado -mode tcl -source fractal.tcl

Vivado% launch_runs impl_1 -to_step write_bitstream -jobs 32
        Vivado% wait_on_run impl_1
        Vivado% write_hw_platform -fixed -include_bit vivado_project/system_wrapper.xsa
        Vivado% q

3. Build PetaLinux project

$ cd petalinux_project
        $ petalinux-config --silentconfig --get-hw-description=../vivado_project
        $ petalinux-build
        $ petalinux-package boot --force --format BIN --fpga --u-boot

4. Copy generated files to microSD card

$ cp image/linux/{BOOT.BIN,boot.scr,image.ub} /path/to/sd/card
