Hi Bruce, I've got another question. I know that in a .bbappend I can specify functions to run during the build procedure, would it be possible to add in a function that would run after the do_configure_prepend() in the linux-rpi.inf file? If I could do that, then I could modify the config file that is produced by that ...prepend() function.
Or the other option is to modify the linux-rpi.inc file itself.
