Does anybody know how to install driver for RTL8153 ? Can I just enable or install it in WP7502 module or do I need to rebuilt kernel? any help appreciated. Thanks.

Hi,

If you are not affraid by Yocto then you can rebuild an image with RTL8152/RTL8153 kernel driver enabled as module:

- In your `linux-yocto_3.14.bbappend` recipe, add:  
`FILESEXTRAPATHS_prepend := "${THISDIR}/files:"`  
`SRC_URI += "file://enable-RTL8153.cfg"`
- In the folder where your `linux-yocto_3.14.bbappend` recipe is located, create a folder “`files`” and create in this folder a file named “`enable-RTL8153.cfg`” with the following content:  
`CONFIG_USB_RTL8152=m`
- In your `mdm9x15-image-minimal.bbappend` recipe, add:  
`IMAGE_INSTALL_append = " kernel-module-r8152"`

Rebuild and flash `yocto_wp75.cwe` image.

Then you should be able to load the kernel module using this command:  
`modprobe r8152`

If you don’t want to generate your own Yocto image then you can use Legato Kernel Module Definition .mdef:

If you are using WP75 release R16.1 or newer, you can build from source.  
Latest Realtek driver source code for RTL8152/RTL8153 is available on their web site:

Hi, I’m trying to do the same kind of thing. The problem is that I’m not too familiar with Yocto and kernel stuff. I’m having a bit hard time understanding how to do this, so is there any specific instructions for newbie how to create a new kernel module and build from source? I tried to create a new folder under mangOH/linux\_kernel\_modules on mangOH VM with downloaded drivers and .mdef-file. Then I tried to rebuild mangOH system as it was advised to do in here ([mangOH Red mt7697 WiFi · mangOH/mangOH Wiki · GitHub](https://github.com/mangOH/mangOH/wiki/mangOH-Red-mt7697-WiFi#rebuild-your-mangoh-system-to-incorporate-the-wifi-patches)). I managed to install the system but somehow it installed it with framework version 18.09.0 (I used to be on 18.06.4) which then broke all my existing applications. Am i anywhere near doing this right and how can I downgrade my device?
