While a couple of the Haswell-based ChromeBooks have been added to
upstream coreboot, but have not heard of anyone with them actually
running yet. I know John Lewis had tried to get the HP ChromeBook
14 (falco) going but was not successful (though he does have the
Chromium/falco branch working), and I assume the same is true for
the Acer C720 (peppy) too, as they are nearly identical. Looking at
it briefly, I'd suspect the issues are related to the display init
or Google's EC, but haven't had a chance to play with one myself
yet.<br>
<br>
I have upstream coreboot running on the Haswell-based Asus ChromeBox
(panther), and have submitted patches for it, but they have not yet
been accepted/merged in. Also works for the nearly-identical HP
ChromeBox (zako). I can throw my branch up on github in the
meantime if would be useful, but that's where I'd recommend starting
(vs the ChromeBooks).<br>
<br>
cheers,<br>

that is known to work with coreboot and has your chipset in it.
You should get several (never just one!) of the haswell
chromebooks, build coreboot, make sure you can make it all work,
then try the port to your board.

coreboot,<br>
<br>
We are interested in coreboot for the Intel
Haswell processors.<br>
coreboot appears to be used in the Acer C720 and
HP Chromebooks<br>
that use Haswell processors. I see no reference
to this processor,<br>
or to these products in the source code that I
downloaded recently.<br>
