Android Pie 9.0.0 for Boundary Devices Nitrogen6X

Android Pie 9.0.0 for Boundary Devices Nitrogen6X


The Nitrogen6X from Boundary Devices is an Embedded single board computer (SBC) based on the NXP i.MX6 applications processor. The Nitrogen6X is an very popular off-the-shelf embedded board designed for middle-low volume markets with a guaranteed 10 year lifespan, FCC Pre-scan results, and a stable supply chain. Industrial temperature and conformal coating options are available.

Due to a different approach adopted by Boundary on how to build the Android final image, their OS was not ready to support important enhancements introduced by Google like Android Verified Boot (AVB).

Due to the popularity of the board, it made sense for Kynetics to build a Android 9 for the Nitrogen6X filling the dots to support Android Verified Boot. AVB is essential for the implementation of the Full Chain of Trust which is crucial for the security of critical systems.

The image provided is not intended for system development, but as an evaluation image for application development purposes, where the system shows a significant entry level of security.

This release requires a new custom bootloader (provided in our download package) with respect to what is provided by Boundary Devices.

Kynetics offers an advanced level of customization for this platform. Contact us us to receive a quote for commercial support.
