Question: USAGE FAULT Occurring in Zigbee

[Kenta]

Hi,

I am using the nRF54L15-DK and nRF Connect SDK v2.8.0 Zigbee-Addon.

In an environment with three devices: Coordinator, Router, and End Device,

When powering on the devices in the sequence of Coordinator -> Router -> End Device, a USAGE FAULT repeatedly occurs on the Coordinator.
However, when powering on the devices in the sequence of Coordinator -> End Device -> Router, the USAGE FAULT does not occur.

Are there any solutions or workarounds to avoid this USAGE FAULT?

Best regards.

Hi Kenta,

This seems to need some additional investigation and information.

If you enable CONFIG_THREAD_NAME in your configuration file, the name for the "Current thread" will be logged if it has a name. The thread name can be a good indicator on where to debug the code.

Are you running one of our samples or your own application?

When powering on the devices in the sequence of Coordinator -> Router -> End Device, a USAGE FAULT repeatedly occurs on the Coordinator.
However, when powering on the devices in the sequence of Coordinator -> End Device -> Router, the USAGE FAULT does not occur.

Could you create a sniffer trace for these two scenarios? If you are not sure what to look for in the traces, you can share it as a .pcap file and I'll take a look. If you are using another network key than the default from nRF Connect SDK, please let me know so I can arrange for you to share it privately.

Best regards,

Maria

Hi Maria.
Thank you for your support.

I'm going on vacation for 3 days starting tomorrow.

I'll try on Tuesday and be able to upload the .pcap file.

Best regards.
