We’ve developed a custom carrier board to use with either the Xavier NX or Jetson TX2 NX. The carrier board has an M.2 Key-E slot for a Wi-Fi module, and we followed the development kit design as closely as possible to ensure compatibility.
What we’re seeing is that the Wi-Fi module works with the Xavier NX, both in the dev kit and on the custom carrier, but with the Jetson TX2 NX, the Wi-Fi module works with the dev kit, but not with the custom carrier. We are using the Azurewave AW-CB375NF Wi-Fi module, which is in the Supported Components List for the Xavier NX. Notably, the SCL for the TX2 NX doesn’t list any Wi-Fi modules.
I’ve attached relevant schematic sections for the Wi-Fi module. Note that it will be difficult for us to provide any outputs from the Jetson software, as this is a headless setup with Wi-Fi as the only means of access (no USB debug, either). However, we can probe the hardware as needed. Any input on this would be appreciated.
