[[PageOutline]]
The Gateworks Venice product family utilizes the NXP i.MX8MM SoC (System On Chip) family offering a large variety of peripherals with a focus on Networking, Security, and Media. See [http://www.gateworks.com/product#ventana here] for a product comparison matrix.

= Venice Software
Venice Software is comprised of many pieces, including the following:
* GSC (Gateworks System Controller) Firmware
* Boot Firmware (ARM Trusted Firmware, DDR controller Firmware, U-Boot Bootloader)
* Operating System (including kernel / rootfs)
Ubuntu is pre-installed on all Venice boards before they ship.

== Choosing a BSP
Gateworks offers several Board Support Packages for the Venice Product family. Which one we recommend depends a bit upon what your goal is and what your experience level is. ** Note: By default Venice boards are pre-programmed with and Ubuntu root filesystem and Gateworks kernel. **
* [#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.'''
- Able to use mainline kernel.
- Supports all Venice 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
* [#buidlroot Buildroot] - intended for custom applications (low flash and memory footprint)
- Fairly up-to-date and/or vanilla kernel support
- Wide variety of packages (including a fairly nice web-admin)
- Console-based build system
- Downloadable SDK and Toolchain available to build apps on a development host without building the entire BSP
[=#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.

[=#third_party_linux]
= Third Party Linux Distros =
While Gateworks cannot fully support all Linux distros, it is relatively simple to overlay a Gateworks Venice kernel onto any non-Gateworks third party Linux distro rootfs image.
The following links will describe what is needed:
1. Linux kernel supporting Venice: [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 Venice. As Venice 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 i.MX8MM 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)
