== 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.
* [#Ubuntu 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.'''
- Uses mainline kernel.
- Supports all Newport features.
- 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
* [#openwrt 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
- easy firmware upgrade (sysupgrade) and factory-default reset mechanism
- Pre-built images available

1. SPI does not currently support full-duplex - issue is being investigated with Cavium
2. RS485 has not yet been fully validated but uses the same shared transceiver as RS232 which has been validated. RS485 half duplex mode would require adding support for TIOCSRS485 or managing the TXEN GPIO (gpio12) from userspace.
3. Requires a board with a Mezzanine connector.
4. HW Compression offload is supported (DEV_CAVIUM_ZIP drivers/crypto/cavium/zip.c) and crypto is supported (DEV_CAVIUM_CPT drivers/crypto/cavium) although there may be additional features that could be supported with additional driver work.
[=#ubuntu]
== Ubuntu ==
Gateworks offers a pre-built Ubuntu distribution using the latest Gateworks kernel as well as instructions on how to build your own Ubuntu based distribution.
* [wiki:newport/ubuntu Newport Ubuntu Wiki and Software]
[=#openwrt]
== OpenWrt Board Support Package (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)
* simple upgrades and factory-reset capability provided by overlay filesystem

[=#third_party_linux]
= 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: [wiki:linux/kernel]
2. Root Filesystem: [#rootfs see below]
3. Bootable media: [wiki:linux/blockdev]
[=#rootfs]
=== 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:
* [http://cdimage.ubuntu.com/ubuntu-core/ Ubuntu Core] - this is a minimal filesystem that you can build off of at runtime by adding packages from various repositories.
* [https://releases.linaro.org/ Linaro] - Linaro has several root filesystems including server, nano, developer, core, and ALIP. Each root filesystem will have different things installed for different purposes. Choose carefully which will work for you.
Notes:
* some root filesystems may require you to manually add a user before booting (ie Ubuntu Core)
* the default Newport bootloader expects to find the Image in the /boot directory on the 2nd partition of type ext2/3/4
[=#linux]
[=#mainline-linux]
= 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:

The following kernel configs should be enabled for the OCTEON-TX CN80XX / CN81XX:
* SERIAL_AMBA_PL011 - ARM SBSA UART
* MMC_CAVIUM_THUNDERX - MMC
* EDAC_THUNDERX - Error Detection and Correction (works with 'edac-util' app from 'edac-utils' package)
* GPIO_THUNDERX - General Purpose I/O
* SPI_THUNDERX - SPI Controller
* I2C_THUNDERX - I2C Controller
* THUNDERX_NIC_VF - NIC virtual function
* THUNDERX_NIC_PF - NIC physical function
* THUNDERX_NIC_BGX - Network Controller (selects MDIO_CAVIUM/MDIO_THUNDER)
* THUNDERX_NIC_RGX - RGMII Network Controller (selects MDIO_CAVIUM/MDIO_THUNDER)
* MDIO_THUNDER (selected automatically by THUNDERX_NIC*)
* MDIO_CAVIUM (selected automatically by THUNDERX_NIC*)
* PCI_HOST_THUNDER_PEM - PCI host controller
* PCI_HOST_THUNDER_ECAM - Enhanced Configuration Access Mechanism for PCIe memory mapped I/O
* ARM_SBSA_WATCHDOG - ARMv8 Watchdog
* CRYPTO_DEV_CAVIUM_ZIP - Hardware Compression / Decompression off-load
* HW_RANDOM_CAVIUM - Hardware accelerated random number generator
Note that there are many kernel drivers using the name 'Octeon' but they typically refer to a different chipset and the CN80XX / CN81XX have more in common with the Cavium 'ThunderX' architecture as that is the SoC core.
