First, we prepare the SD card on a desktop machine. These instructions are for an 8G card, which affects on the second cgpt add call - you can adjust as required.

# Write the signed kernel to the kernel partition:
dd if=${MNT}/boot/vmlinuz.signed of=${DEV}p1
Did you modify the above "/dev/mmcblk1" with the proper value?
Are you sure that the size of the signed kernel is smaller than 32768-34+1=32735 ? (Although I may be wrong.)
Did you modify the above "/dev/mmcblk0" with the proper value?
on my "desktop" machine /dev/mmcblk0 is the sd card reader. i tried both sd card and usb pen drive (/dev/sdb)
Did you modify the above "/dev/mmcblk1" with the proper value?
/dev/mmcblk1 is the sd card reader on the c100pa, that seemed to work

i think 34 is the offset, and 32768 kb is the size of the kernel partition. the kernels i've tried so far were all less than 6mb.
i'll try to compile the kernel in arch directly on the flip so i don't have to cross compile. (https://chromium.googlesource.com/chrom ... rty/kernel)
perhaps the release they've mentioned in the howto works (release-R43-6946.B-chromeos-3.14)

# Guess which kernel partition is the latest. Run cgpt show and see
# which one (KERN-A or KERN-B) has the highest priority.
cgpt show /dev/mmcblk0
# Copy the ChromeOS kernel to the root filesystem,
# In this example we'll assume it was KERN-B:
dd if=/dev/mmcblk0p4 of=${MNT}/boot/chromeos.kernel.signed
I also followed the guide on https://wiki.debian.org/InstallingDebianOn/Asus/C201, alas it did not work for me as well. Booting from the sd-card goes into black screen... I copied the kernel with the highest priority and it did not work:
I first tried copying from Kernel-A as it has the highest priority, but when it did not work I tried with Kernel-B and the result was still failure. Has anyone find a solution to this?
Also is there anyone who has compiled kernel (like Gentoo) or that of ARM and satisfied with it? It seems like I am going to try upstream kernel soon.
What happens if you press Alt and SysRq keys and REISUB after you get into black screen?
If it reboots, kernel is running even after you get into black screen. Thus, it may relate to graphical issue.
Also just for testing purposes ( since the kernel is up and logging ), did you try raising your backlight with the brightness keys?
I have one particular laptop that no matter what kernel / paramaters are use gets the backlight immediately set to zero on boot, and has to be raised with the buttons each and every boot.
Backlight may be worth looking into....

Your love life will be... interesting.
How did it know?
The U.S. uses the metric system too, we have tenths, hundredths and thousandths of inches
Hello everyone. Im experiencing the same "black screen" issue.Tried all 3 kernels with same result.

Asus c201 keyboard don't have a sysrq key. Tried with an external usb keyboard, but doesnt seem to recognice it.
That blog post is a critisism on the "Debian On" section of the wiki.
It has nothing to do with the ability to run Debian on Chromebooks.
I have just bought this laptop specifically to run GNU/Linux on it, in particular Debian.
I'll be using the Libreboot guide you linked to, I'm pretty confident that it will work because this laptop is now being sold by the author of that guide, with Libreboot and Debian pre-installed.
This is one of the very few laptops that can run entirely without proprietary software.
For those who try to install a native linux distribution on C201 -- try Arch Linux ARM first. It is the only step-by-step instruction on the internet I could find that really worked for me. Yes, we are in 2017 already.
In last week I've tried so far:
* Debian (obviously) - didn't work;
* Fedora - didn't work;
* Devuan image - worked only command line and I couldn't build the image myself as lots of information is missing and the build scripts are broken;
* Arch - worked as expected. I could set up whole system with GUI (Weston/Wayland on fbdev) in a few hours. The instruction I used was for Asus Chromebook Flip C100P, but it did work for me with out changing even one bit.
I don't have a working HDMI output yet, which is a big deal for me. As a next step, I'll try to compile the latest mainline kernel and try to set up the HDMI port from there.
Is there any news on installing debian on the C201? After installing debian on the sd card and booting from it, I also get a blank screen. I've followed this guide. Can anyone help?
I have GOOD and BAD news regarding debian on the c201. The good news, it can be installed, and get to work. The bad news, we need to reconfigure Xorg without CONFIG_VT. Google has disabled CONFIG_VT in the kernel, in order to prevent the creation of consoles and the starting of Xorg from current stable.
