I'm curious about how you build code and test on Chromebooks. Do you
build in cros environment or pure linux
(https://archlinuxarm.org/platforms/armv8/mediatek/acer-chromebook-r13).
I've a MT8183 based Chromebook (HP 11a) and I've tried to run a
upstream kernel on it. cros is too heavy for me and I doubt I could
use it. I've tried the pure linux and could boot up with console, but
display does not work. If you use the pure linux environment, could
you share how it works?

Chun-Kuang.
