I had a problem about pcie8997 driver loading issue(Firmware Init Failed).
I had downloaded pcie8997 driver code form NXP web site
and we build pcie8997 driver by yocto cross compiler.
we put associated files to target imx8mmevk target borad.
Firmware Init Failed issue happend !

pcie8997 driver version :
      (1)PCIE-WLAN-UART-BT-8997-U16-X86-W16.68.10.p16-16.26.10.p16-C4X16640_V4-GPL
      (2)PCIE-WLAN-UART-BT-8997-U16-X86-W16.68.10.p16-16.26.10.p16-C4X16640_V4-MGPL

GPL and MGPL have the same result.

The load driver procedure as following
cp pcie8997_wlan_v4.bin /lib/firmware/mrvl/pcie8997_wlan_v4.bin
insmod mlan.ko
insmod pcie8xxx.ko drv_mode=1 fw_name=mrvl/pcie8997_wlan_v4.bin cfg80211_wext=0xf ps_mode=2 auto_ds=2

Hi J S

one can look at

mwifiex: PCIe8997 chip specific handling - Patchwork 

and try to debug if correct firmware loaded in driver code:

pcie.c\mwifiex\marvell\wireless\net\drivers - linux-imx - i.MX Linux kernel 

Best regards
igor
