Hi... There

Hope all are doing well

Right now, I'm dealing with the *TP-Link Bluetooth dongle*.
My goal is to add the Bluetooth functionality with the Yocto custom image

I'll have to manually add the *rtl8761b_fw.bin* file with the image

Here is the good post for the same

Now, my problem is, I'm getting some errors after adding it's firmware file

Here is the steps, which i have gone through

1. Created linux-firmware file under recpies-kernel directory

After some research i got to know that the Bluetooth dongle, that I'm using is unsupported by activating the Bluetooth drivers only by menuconfig

there already is a linux-firmware recipe meta/recipes-kernel/linux-firmware/linux-firmware_20220708.bb

2. added the rtl8761b_fw.bin to /files directory under linux-firmware file

OK

3. Created .bbappend file as per the available kernel name called *"linux-stm32mp_%.bbappend"*

bbappend should be for linux-firmware recipe.

     # Drivers for the TPL-Link Bluetooth dongle
     IMAGE_INSTALL += "linux-firmware-rtl8761b_fw"

4. installed the .bin image with the custom recipes file called custom-image.bb as follows

I think it will be called something else then perhaps linux-firmware-rtl8761b or some such. Avoid using '_' in the name as its used a version separator and can confuse the packaging

5. bake the image with bitbake custom-image

here is the tree of the directories


The error screenshot is mentioned here




The content of the .bbappend file is listed here



Can any one help me here ?
All suggestions and comments welcome :)
