Topic: building and booting a firmware image

Hello all,

So I'm interested in building and booting a firmware image. I can build the kernel, but the kernel is only part of the picture. What I'm looking for is the recipe for the complete image. My first goal is to boot with Python already in the rootfs (as opposed to being on a USB stick). Has anyone gone down this path?

Re: building and booting a firmware image

The usual strategy is to:

1) use "dd" to transfer the root file system as a single file to some storage (perhaps a USB dongle).
2) unpack that cramfs image to something writeable
3) modify the files to suit your purposes
4) repack the file system as cramfs, and pad it
5) reburn the root file system from this image.

A few people have done this in the past.

More info in this thread.
