Question about RW612 OTBR Thread Certification Architecture

Hello NXP Team,

I noticed the Thread Group certified component:

"NXP RW612 Wireless MCU With Integrated Tri-Radio OTBR"

(Thread 1.4)

I also found separate certifications for:

- NXP i.MX MPU With IW610 Tri-Radio OTBR

- NXP i.MX MPU With IW612 Tri-Radio OTBR

- NXP RW612 Wireless MCU With Integrated Tri-Radio OTBR

I would like to better understand the certification architecture used for the RW612 OTBR certification.

Could you please clarify:

1. Was the certification achieved using RW612 as a standalone MCU/RTOS-based Thread Border Router?

2. Was an external RCP/NCP device used in the certified configuration?

3. Which software platform was used during certification (FreeRTOS, Zephyr, or another platform)?

4. Is there any public reference design or documentation describing the certified RW612 OTBR implementation?

Our goal is to understand whether the RW612 OTBR certification represents a standalone MCU-based Thread Border Router solution rather than a Linux-host-based OTBR architecture.

Thank you for your support.

Best regards,

Kyonghwan Cho

Re: Question about RW612 OTBR Thread Certification Architecture

Hello,

Hope you are doing well. My name is Ricardo and I have been assigned this case.

A1: Yes. The RW612 OTBR certification is a true standalone, single-chip solution.

A2: No. Unlike the i.MX MPU + IW610/IW612 OTBR certifications (which use a Linux host with an external IW6xx radio co-processor in RCP mode), the RW612 certification does not use any external RCP or NCP device.

A3: Let me confirm.

A4: For specific details on the test configuration, test reports, or certification scope, please contact the Thread Group directly at threadgroup.org.

Best Regards,

Ricardo

Hello @KyonghwanCho ,

Thank you for your patience.

I have the confirmation that the SW platform used was FreeRTOS.

Also, please check below OTBR user guide and build guide
