But what about if the module is not in the # CONFIG list , like it is the case for my backlight device for example ?
If the driver exists in the Linux Kernel then you can simply request us to add it to our OS by default set to “m”. If the driver does not exist in the Linux Kernel then you need to add it externally.
For these other 2 devices you listed, do you know where there drivers can be found?
A part of that, have you understand why i’m not able to build the yocto because of the missing receipe ( or the wrong pointed by the linux-firmware .bb file ?
This is a known issue see my comment in this other thread here: Installing deb packages with the Yocto Project - #2 by jeremias.tx
