Hi xu.ji@hirain.com,

You can follow the below link.

https://community.nxp.com/docs/DOC-95333

This will help you to create custom meta layer in yocto and also installing a new file to rootfs through yocto.

Hi Xu,

if you want to let linux load your module automatically when linux boots, you can do like this :

For example, module's name is my_module.ko.

# sudo echo "my_module" > /etc/modules-load.d/my_module.conf

Have a nice day!

Hi xu.ji@hirain.com ,

I believe you can write the command suggested by weidong.sun in your conf file and make it a part of rootfs through your yocto. Then it will be part of your image and no need to manually run any commands.

Let us know if you still face any issue.
