Hello,
I've made a first attempt at getting OpenEmbedded working on the E3. I've got to the point where it will boot into a ramdisk, and I can get a shell via both Serial and the console. Dropbear sshd also seems to work. Patches, and files that have been built are at http://hu.gs/pub/E3
I've also had a quick look at getting OPIE working, and have got it building, however the colours don't work properly. It certainly gets as far as the calibration screen though.
Thanks
David
