[Buildroot] Implementation Procedure for i.MX93 Custom Board

Thu Oct 16 05:37:38 UTC 2025

Hello,

I have enabled the MWIFIEX Wi-Fi driver in Buildroot for my platform. 
During validation, I observed that the driver fails to initialize the 
firmware properly. Please find the log details and observations below.

Steps Performed

Enabled MWIFIEX configuration in Buildroot.

Loaded the driver using the command:

modprobe moal mod_para=nxp/wifi_mod_para.conf

Could you please help me identify the reason for the firmware activation 
failure and guide me on how to resolve it?

Thanks & Regards,
