[RW612] How to analyze Stability Issue

AlexLiang — Tue, 26 Aug 2025 14:54:10 GMT

Background:

I'm using the RW612 EVK(with freeRTOS) to do pre-evaluation.

And is trying to make the wifi-bt coex work well. During this process, I encountered some stability issue but has no knowledge how to debug further.

I have searched the NXP docs for RW612 platform, but didnot find some documents/trainings guide me how to do stability issue analyzing.

Could you help to share any infos about how to do stability issue analyzing with rw612 platform ?

BTW, I'm using the SDK 1.2.3 SDK_25_06_00_FRDM-RW612

Thanks a lot!

Hello,

Hope you are doing well. Are you using any of the coexistence examples from the SDK?

I would recommend checking this Application Note: Coexistence Overview for RW61x

Also, you could check section 8 of this User Manual: NXP Wi-Fi and Bluetooth Demo Applications for RW61x

Hope this helps!

Regards,

Ricardo

Hi Ricardo,

Thanks a lot for you infos! And yes, I did checked these 2 docs previously for wifi & bt coex cases.

And further background is, while developping basing SDK_25_06_00_FRDM-RW612, there is a stability issue that EVK board will run into crash, log print like below,

call_socket_task_init
call_socket_task_init
Creating new socket.
socket_task_init socket thread created
do while
tcp_connect_thread wifi tcp Connecting...
tcp_connect_thread wifi tcp Connecting... IPv4

do while
[2025-08-26 21:43:10.261]# RECV ASCII>
AS

And the last "AS" print, I guess should be assert, but I did not get a method from the SDK / User Manual docs can help to do further root causing this issue.

So could you help to share some guide help me to find a easy way to debug this stability issue?

Best Regards,

Alex

Hi Alex,

Could you please specify what SDK example are you using as a base?

Did you modify something on the example? How are you testing this "stability issue"?

I would recommend checking this Application Note: NXP Wi-Fi and Bluetooth Debug Feature Configuration for RW61x Evaluation Board
