Integrating IEEE 802.1X EAP Supplicant in MQX 4.2

[Prabhath]

Hello all,

We are working on an embedded application using MQX 4.2 on a Kinetis K66 MCU, and we now need to integrate IEEE 802.1X (EAP) support for port-level LAN authentication.

To proceed, I have a few questions:

1. Are there any existing examples, demo projects, or documentation for implementing 802.1X on MQX 4.2 (or similar Freescale/NXP stacks)?

2. Is there any lightweight 802.1X supplicant library available that’s suitable for resource-constrained MQX systems (preferably C-based and portable)?

3. Has anyone tried porting wpa_supplicant or other embedded EAP clients into an MQX environment?

Any pointers, experience shares, or example projects would be greatly appreciated.

Thanks in advance!

Hello @Prabhath ,

Thanks for your post.

Please refer to the Freescale Embedded Solutions Based on ARM Technology Guide - Brochure.

The Kinetis K series does not support IEEE 802.1X by NXP. Only the KW series supports it.

In addition, MQX 4.2 is no longer supported. You can consider using MQX™ v5 Software Solutions | NXP Semiconductors.

Sorry for the inconvenience. Thank you for your understanding.

BRs,

Celeste

Thank you for the reply.

I would like to clarify a few more points. Is it possible to modify the application firmware to integrate IEEE 802.1X support?

According to the RM, it supports IEEE 802.1q.
