Help enabling the BT_QCA driver

Help enabling the BT_QCA driver

Hello,

I'm using Yocto for a project at work and I need to enable the btqca driver. I have tried using the menuconfig option in Yocto but the driver doesn't appear there. I have also modified the .config file manually inside the build-** folder but the file gets rewritten with the old version when I build the project.

What should I do here for enabling this driver?

Thank you.

Hello,

I wanted to add that I have been able to enable the driver using menuconfig by enabling its dependencies.

The problem I'm facing now is that Yocto is not building the kernel object files (.ko), not even the ones it was building before. As far as I know I have only changed the configuration to build this new driver but I could be wrong and maybe touche where I shouldn't.

Is there a way to tell Yocto to build those kernel objects?

Thank you.

depending upon which kernel recipe is in use you might be able to use
kernel config fragments where you add a file with needed configs which
is then merged into the final .config file
by build system, linux-yocto kernel uses this method extensively.
Create something like bt.cfg with BT_QCA = m and then add bt.cfg to
SRC_URI this should hopefully enable the
driver and emit it as a separate output package like
kernel-module-btqca or somesuch. Which you can add to your image via

MACHINE_EXTRA_RRECOMMENDS:append = " kernel-module-btqca" in machine
conf or local.conf file.

Could it be that you disabled the support of the kernel modules in the kconfig by accident?
This config in particular,
```
CONFIG_MODULES=y
```
