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.

Hi @vivek338
Please refer to the document for imx8m-mini evk (How to Integrate 88W8997 to iMX8MM-EVK & L5.4.24_2... - NXP Community)

You can use modprobe to load driver and firmware then use wifi. Images from Yocto and Prebuild both should include them in it.

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
Harvey
