Hello,

I want to update the rootfs after building a yocto image that contains personalized script at init.d and rcS.d. Does any one have an idea how to update bith the kernel with the rootfs. Knowing that I tried with the fastboot but this command doesn’t work with the WP7607.

I am trying to do the same thing for the mangOH red platform. Can someone help on how to add a custom script to run it on boot?

Hello,

Some say we should add our own layer and put our script in the layer in order to insert it in the image.

This could help
