Setup
The Wi-Fi Regulatory Utility (lru) requires that special manufacturing firmware files be used. The regulatory package includes the manufacturing firmware files and the installation step copies them to the firmware directory.
The following tables show the links that must exist for the manufacturing firmware to load correctly for each supported radio variant. Note that the links will already exist to support the normal production mode. However, some of the links must be manually modified to point to manufacturing firmware files. Not all links will need to be modified; most files are the same in both production and manufacturing modes. Files that must be manually changed have been bolded.
See the following for an example of changing a firmware file link:
cd /lib/firmware/brcm
ln -sf brcmfmac4373-sdio-mfg_<version>.bin brcmfmac4373-sdio.bin
ln -sf brcmfmac4373-div-mfg.txt brcmfmac4373-sdio.txt
Reboot device.
