Android Oreo for Toradex Apalis i.MX8QM

Android OS for Toradex Apalis i.MX8QM


The Apalis iMX8 is a small form-factor System on Module based on the latest NXP i.MX 8 SoCs. The most performant i.MX 8 SoC, the i.MX 8QuadMax, features 2x Cortex-A72 and 4x Cortex-A53 application processor cores, and 2x additional Cortex-M4F, which also include a FPU, microcontroller cores. The integrated high-performance dual GC7000 3D GPU supports Open GL ES 3.1 and Vulkan on up to 4x 1080p or one 4K display.

The Apalis iMX8 is pin-compatible with the other SoMs in the Apalis family. This allows existing Apalis-based products to easily scale and migrate to the new Apalis iMX8. All Toradex's Apalis Carrier Boards are compatible with Apalis i.MX8.

Kynetics, as part of the Toradex early access program, has worked on the Android Kernel for the Toradex Apalis i.MX8QM and built an image based on Android 8.1 (Oreo) compatibe with the Ixora carrier board. The image boots form the SD-Card and it is very easy to program and test. The image supports also OTA updates through Update Factory
