First Zynq UltraScale+ based 96Boards SBC runs PetaLinux

Mar 22, 2018 — by Eric Brown — 2096 views

Avnet has launched its open-spec Ultra96 96Boards CE SBC for $249, featuring a Zynq UltraScale+ ARM/FPGA SoC, WiFi, BT, 4x USB, a mini-DisplayPort, and support for Linaro’s 96Boards.ai.

Avnet’s Ultra96 (AES-ULTRA96-G) was unveiled earlier this week as part of Linaro’s joint announcement of its 96Boards.ai program for unleashing the potential of artificial intelligence technology on selected Arm SoCs. Now this Zynq UltraScale+ based, 96Boards CE standard (85 x 54mm) SBC is available for pre-order at $249 with shipments starting in May.

The Ultra96 is one of three 96Boards.ai compliant boards featured on the 96Boards.ai site, along with the upcoming Rock960 and HiKey970. Two more boards will join the list in the coming months: Arrow’s $199, Snapdragon 820E based DragonBoard 820c CE Extended board and Rockchip’s 96Boards Enterprise Edition form factor Rock960 Enterprise Edition, a higher-end version of the similarly RK3399Pro-based, CE form factor Rock960. Socionext is also planning an 96Boards.ai board.

Avnet did not mention 96Boards.ai in its announcement, although it did note the capability of the Ultra96’s Xilinx Zynq UltraScale+ MPSoC system-on-chip’s FPGA for hardware acceleration of machine learning algorithms. The board is designed for machine learning, automotive, and industrial IoT.


Chameleon96

According to Avnet, the Ultra96 “adds a wide range of potential peripherals and programmable logic acceleration engines not previously available on the 96Boards platform.” It is true that this is the first official 96Boards entry to incorporate an FPGA. Last year, however, NovTech and Arrow launched a 96Boards CE-like Chameleon96 SBC that runs Debian on a Cyclone V SE SoC, and which is available for $129.

The Chamelon96’s FPGA is not as powerful as the 16nm-fabricated Zynq UltraScale+ MPSoC, which competes directly with the Intel/Altera Stratix 10. This is despite the fact that the UltraScale+ ZU3EG A484 model used on the Ulta96 has the second-lowest FPGA specs of the 11 available UltraScale+ EG models, with 154K logic cells, 141K flip-flops, and 70K LUTs.

Compared to Xilinx’s Zynq-7000, which runs on a number of Avnet’s Zedboard.org backed boards, such as the MiniZed, the UltraScale+ has a faster, 1.5GHz quad-core, Cortex-A53 CPU block, and more powerful Mali-400 MP2 GPU and FPGA. The UltraScale+ also adds two 600MHz Cortex-R5 MCUs with vector FPUs and memory protection units for improved real-time processing.

The Ultra96 is equipped with 2GB of Micron LPDDR4, and boots from the provided 16GB Delkin microSD card, pre-loaded with Xilinx’s PetaLinux. The distribution includes a desktop environment viewable through the board’s mini-DisplayPort. The system can also be accessed via a web server using the integrated wireless access point capability enabled by the board’s 802.11b/g/n radio. Bluetooth 4.2 is also available.

The Ultra96 is a simple board compared to some CE entries such as the Hikey 960. In addition to the mini-DP, WiFi, and BT, it provides dual USB 3.0, one USB 2.0, and a micro-USB 3.0 port.

The 96Boards CE-standard CE 40- and 60-pin expansion headers are available with an optional Grove starter kit, and presumably they can run other 96Board Mezzanine add-ons as well. A USB-based JTAG connection is also optional.

A few more details should appear in the coming weeks or months. Schematics are available, but at publication time the 96Boards hardware guide link erroneously linked to the guide for the MediaTek X20 Development Board.

Specifications listed for the Ultra96 include:

  • Processor — Xilinx Zynq UltraScale+ MPSoC ZU3EG A484 (4x Cortex-A53 @ 1.5GHz); FPGA with 154K logic cells, 141K flip-flops, and 70K LUTs; Mali-400 MP2 GPU; 2x Cortex-R5 MCUs
  • Memory/storage:
    • 2GB LPDDR4 RAM (“512M x 32” configuration).
    • MicroSD slot with 16GB card pre-loaded with PetaLinux

    • 2x USB 3.0 host ports
    • USB 2.0 host port
    • Micro-USB 3.0 “upstream” port
    • I2C interface
    • 40-pin low-speed connector
    • 60-pin high-speed connector
