Verdin AM623 Radio single channels RED test

Technical Support

Dears,

we need to perform single channel tests of the radio module mounted on the SoM Verdin AM62.

Do we need to load a special custom firmware on the radio module to access raw channels and set specific power transmission?

This is required for the RED tests of our product. How can we get support for this?

Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

Radio Module Testing on Verdin AM62

The Verdin AM62 SoM includes an optional Wi-Fi and Bluetooth module (1). For RED (Radio Equipment Directive) compliance testing requiring single channel tests and specific power transmission control, you’ll need specialized firmware for the radio module.

Wi-Fi and Bluetooth Module Information

The Verdin AM62 features an optional Wi-Fi and Bluetooth interface (1). The module is designed to support wireless connectivity, but the standard firmware may not provide the low-level access required for RED certification testing.

Support for RED Testing

For RED compliance testing that requires:

  • Raw channel access
  • Specific power transmission control
  • Single channel testing capabilities

You’ll likely need custom firmware or specialized test modes for the radio module. This type of testing typically requires manufacturer-specific tools and firmware that can bypass normal operational constraints.

Getting Support

For specialized radio testing requirements and custom firmware access, I recommend:

  1. Check the Software Ecosystem: Review the comprehensive software options available (2)
  2. Hardware Documentation: Consult the complete hardware specifications in the datasheet (3) (1)
  3. Development Resources: Explore the development resources section for additional tools (2)

Since RED testing requires specialized radio firmware and tools that may not be part of the standard software distribution, you may need to work directly with the radio module manufacturer or explore partner solutions in the software ecosystem.

Hello @dm-andreapedica,

To run the test mode we need to provide you a package that requires an NDA.
We will reach out via email to get this sorted out.

How to enable the test mode itself is not covered under the NDA and I will share below, once you have received the package from us, you will be able to follow these steps.

To enable the test mode, you need to build an OS image with Yocto using the meta-toradex-wifi layer: GitHub - toradex/meta-toradex-wifi at scarthgap-7.x.y
The instructions on how to add the layer alongside with the package are in the layer’s readme.

For the Verdin AM62, only BSP/Torizon OS 7 have support for the test mode.
This layer is only compatible with BSP/Torizon OS 7.2.0 or newer.

If you are using Torizon OS and have not built it with Yocto in the past, you can follow the instructions on the following page: Build Torizon OS from Source With Yocto Project/OpenEmbedded | Toradex Developer Center

Labtool is not used for the WiFi module on the Verdin AM62.
Therefore, you can add the following to your local.conf file:

IMAGE_INSTALL:remove = "labtool"

For instructions on how to enable to specific test modes, please check the following application notes: https://www.nxp.com/docs/en/application-note/AN14114.pdf

Note that the WiFi chipset used in the Verdin AM62 is the IW416.

Best Regards,
Bruno
