Compute Module • Re: WiFi module missing on CM4 modules after image restore

modprobe brcmfmac has brought wlan0 back. why though? this image was made from a working CM4 and has been restored to another CM4.
Modprobe said:

modprobe: ERROR: ../libkmod/libkmod-index.c:790 index_mm_open() magic check fail: 0 instead of b007f457

but it seems to have brought the interface up.

something wrong with my initrd?
