September 10, 20214 yr I know that since 6.9.1 there's a overlayfs on /lib/firmware and /lib/modules to "make it possible to install 3rd party modules at boot time" I need to add some bluetooth driver file to /lib/firmware to be installed during boot. The overlayfs allows me to write on /lib/firmware (that ends up on /var/local/overlay/lib/firmware) but the files I add there disappear after a reboot (obviously). I don't understand how I'm supposed to use it to install 3rd party modules (or in my case a patch) at boot time. I understand how I could is this for modprobe, is this the only use case supported? Do I need to regenerate bzfirmware? If so, is there a tutorial for that? My actual problem: [ 16.149827] Bluetooth: hci0: BCM: firmware Patch file not found, tried: [ 16.150209] Bluetooth: hci0: BCM: 'brcm/BCM20702A1-0a5c-21e8.hcd' I have the hcd file, but not sure how to have it available at that point. Thanks for the help.

September 10, 20214 yr Author That doesn't seem to work. The go file gets executed way after the bluetooth module gets loaded. What I end up doing is: on go file I copy the patch and rmmod/modprobe all BT modules. That seems to work fine.
September 10, 20214 yr Community Expert That is the only way to do it as far as I can see. Even with a plugin it will execute after kernel module is loaded so would need to be removed and reloaded within a plugin
