Re: Best way to make application specific Linux for pi2?

this is semi bare-metal

Re: Using a game controller with the pi

usb+wireless+multi-commands+game controller+???
lot of work and from what you ask you don't want to code a lot
you should start with 2 linux one in ssh and the one connected with your controller to send it commands
or the good usb wip bare-metal driver (but you have to code a big lot this way

Re: [Experimental] Loading a kernel using the ethernet port

your code goal is near kexec but best
usb stick and also wire (without ethernet protocol)
tools needed : editor, assembler, fsck ...
anyway why don't you have a RPI2 ???

Re: [Experimental] Loading a kernel using the ethernet port

hi
i didn't read all your code but i think it should have support for usb too ;)
is it based on a custom buffered "kexec" ?
if yes multi-boot from anything is ours with your code ;)
do you plan to add some small tools to rescue a partition/os or to just be able to work ?
