Applicable for

Apalis iMX8 | Colibri iMX6ULL | Colibri iMX8X

Introduction

The AW-CM276NF is a Wi-Fi & Bluetooth M.2 LGA Type 1216 module. The device is based on the Marvell 88W8997 chipset and implements the same reference design. For more information about compatible setups please check AW-CM276NF - Azurewave peripheral database.

How to get started

We have a step by step Getting Started Guide for the following modules:

Colibri iMX6ULL - Basic Wi-Fi usage
Colibri iMX8X - Basic Wi-Fi usage with Torizon
Apalis iMX8 - Basic Wi-Fi usage with Torizon
Verdin iMX8M Mini - Basic Wi-Fi usage with Torizon

After following the step-by-step guide above, you can visit our article WiFi Support on Toradex’s Linux Images with complementary information.

Embedded Linux - Software Support Status

The on-SoM Wi-Fi module has a device driver and corresponding firmware included in our BSP Layers and Reference Images for Yocto Project as well as TorizonCore by default.

BSP 5
BSP 3
BSP 2.8

The device driver included in BSP 5 is the Marvell WiFi-Ex driver from Mainline Linux kernel, along with its corresponding firmware.
Some use cases - such as Wi-Fi client mode + Bluetooth - don't work with this driver. If your use case does not work, please contact our support, as we are doing some tests with the downstream NXP drivers and they seem to work well for some use cases that are not supported by the mainline driver.

Tip: The only SoM with on-SoM Wi-Fi supported by this BSP version is Colibri iMX6ULL.

The device driver included in BSP 3 is the Marvell WiFi-Ex driver from Mainline Linux kernel, along with its corresponding firmware.
Some use cases - such as Wi-Fi client mode + Bluetooth - don't work with this driver. If your use case does not work, please contact our support, as we are doing some tests with the downstream NXP drivers and they seem to work well for some use cases that are not supported by the mainline driver.
You are also encouraged to try a newer Toradex BSP version, if possible. Newer kernel versions might have your specific bug fixed.

Certification documents for Azurewave AW-CM276NF Wi-Fi / Bluetooth module

For information about Certification, please refer to Certification documents for Azurewave AW-CM276NF Wi-Fi / Bluetooth module.

Often, to certify your final product, the regulatory agency will require that you configure the Wi-Fi module in a manufacturing mode. This is only possible with the NXP driver. We are working on documenting it, meanwhile contact our support to learn more.
