Hi
Issue resolved as I am using older board of IMX8MMINI and I found answer in another forum that the older versions are using Qualcomm wifi chip i.e. QCA9377 and the supported linux version is L5.4.24 . But my question is, is that ok to use older version of linux for further development? if not then how I can install QCA9377 driver in latest linux version.

From the log, there seem no wifi related drivers and firmware loaded from your current image.
You can try the document that I shared with you or try our prebuild (Embedded Linux for i.MX Applications Processors | NXP Semiconductors) or build it by yocto.
Best regards
