The Gateworks Newport product family utilizes the Cavium ARM ThunderX CN80xx / CN81xx SoC (System On Chip) offering a large variety of peripherals with a focus on Networking, and Security. See here for a product comparison matrix.

JTAG Programming

The Gateworks JTAG dongle (GW16099) is available in the Newport Dev Kit as well as on the Gateworks web store here

All Newport boards have a 10-pin JTAG header which provides:

  • JTAG Programming for embedded FLASH - see here for instructions
  • Serial Console access via UART0 (/dev/ttyAMA0)

Please note, the Linux software is supported for programming Newport (jtag_usbv4 required). Windows is not supported at this time. (serial console through Windows does work).

Board Support Packages (BSP) Software

Choosing a BSP

Gateworks offers several Board Support Packages for the Newport Product family. Which one we recommend depends a bit upon what your goal is and what your experience level is

  • OpenWrt - intended for wireless routers and access points (low flash and memory footprint)
    • Recommended for networking users wanting to create a headless router, VPN, basestation, wireless access point and more. Produces by far the smallest storage and memory footprint but users new to Embedded Linux will have a bit of a learning curve
    • Fairly up-to-date and/or vanilla kernel support
    • Latest wireless drivers (via linux-backports)
    • Custom application config and init system (nice for small footprint, but can make adding support for additional packages more work)
    • Wide variety of packages (including a fairly nice web-admin)
    • Console-based build system (expect 60mins to build BSP for a specific board family)
    • Downloadable SDK and Toolchain available to build apps on a development host without building the entire BSP
    • Pre-built images available
  • Ubuntu
    • Recommended for developers trying to heavily leverage opensource software packages or libraries that are not supported by the other BSP's. This is the most user-friendly for developers new to Embedded Linux but will not produce a very trimmed down filesystem image.
    • Documentation provided to use Ubuntu pre-built packages and debootstrap to create a root filesystem in minutes
    • Native compilation: no SDK or cross-toolchain needed
    • Pre-built images available

The following table may also help in choosing what BSP is right for you:

Feature OpenWrt Ubuntu Notes
Pre-built images Yes Yes
Storage Needed <256MB 2GB or larger
Build-System Yes No 1
Toolchain SDK Native 2
Web-Admin Yes No 3

Notes:

  1. The OpenWrt BSP contains an integrated build-system to build the toolchain, kernel, and root filesystem from source. For Ubuntu, step-by-step instructions are provided to build an bootable system in 10 or so steps.
  2. The OpenWrt BSP's provide a downloadable SDK for cross-compiling applications on a development hosts. For Ubuntu native development and compilation is supported.
  3. OpenWrt is designed to be a wireless router and has an integrated web-admin for configuration and control.

OpenWrt Board Support Package (BSP)

Newport OpenWrt BSP:

The Newport OpenWrt BSP provides the following:

  • Linux 4.x kernel (fairly vanilla)
  • latest wireless drivers (compat-wireless)
  • tuned for minimal FLASH/memory footprint (entire distro fits on embedded 16MB FLASH)

Ubuntu

Gateworks offers a pre-built Ubuntu distribution using the latest Gateworks kernel with Freescale patches as well as instructions on how to build your own Ubuntu based distribution.

Third Party Linux Distros

While Gateworks cannot fully support all Linux distros, it is relatively simple to overlay a Gateworks Newport kernel onto any non-Gateworks third party Linux distro rootfs image.

The following links will describe what is needed:

  1. Linux kernel supporting Newport: linux/kernel
  2. Root Filesystem: see below
  3. Bootable media: linux/blockdev

Root filesystem Sources

There are several sources of pre-built root filesystems that are compatible with Newport. As Newport uses an ARM 64bit based SoC, you need to use something that is compatible with an ARMv8 instruction set. Many pre-built distributions will reference 'arm64' which means 'ARM 64-bit' which is appropriate for the CN80XX / CN81XX SoC.

Some popular third-party sources:

  • Ubuntu Core - this is a minimal filesystem that you can build off of at runtime by adding packages from various repositories.
  • Linaro - Linaro has several root filesystems available.

Notes:

  • some root filesystems may require you to manually add a user before booting (ie Ubuntu Core)

Mainline Linux Kernel support

Gateworks actively participates in the development of the Linux kernel.

Cavium licenses CPU core IP from ARM and the name they give the CPU core within the OCTEON-TX CN80XX / CN81XX is the Cavium 'ThunderX'. Therefore many of the peripheral drivers within the Linux kernel have 'thunderx' in their name and more often then not the 'OCTEON' name refers to the older OCTEON MIP64 core.

The following table shows what OCTEON-TX CN80XX / CN81XX peripherals support is available in the mainline kernel starting from 4.13:

Feature Support Notes
SMP Yes
serial UART Yes
I2C Yes (4.9+)
Networking MAC (thunderx_bgx) Yes (4.2+)
Networking PHY (thunder_xcv) Yes (4.9+)
PCI Yes (4.6+)
SPI Yes (4.9+)
MultiMediaCard eMMC / microSD Yes (4.12+)
HW RNG (Hardware Random Number Generator) Yes (4.9+)
HW Compressions offload Yes (4.12+)
Crypto Yes (4.11+)
RTC Yes
LED/GPIO Yes (4.14+)
USB 3.0 Yes
mSATA Yes
CAN bus Yes
