Hello Laurentiu-Cristian,

The nvram file with 'raspberrypi' in its name is not present in the 
rpi-wifi-firmware blob; you need to create it yourself. As an example, 
this is what I use in a post-build script for a RPi4:

   ### create missing nvram file for Raspberry Pi 4
   _TARGET_DIR="${TARGET_DIR}/lib/firmware"
   src_file=brcm/brcmfmac43455-sdio.txt
   dst_file=brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt
   if [ -f ${_TARGET_DIR}/${src_file} ] && ! [ -h 
${_TARGET_DIR}/${dst_file} ]; then
	ln -rs ${_TARGET_DIR}/${src_file} ${_TARGET_DIR}/${dst_file}
   fi

Kind regards,
Andreas
