READ BELOW TO FIND OUT WHY:

BEFORE POSTING/COMMENTING, YOU MUST HAVE READ, ACCEPTED, AND ATTEMPTED TO UNDERSTAND THE COMMUNITY INFO (DENOTED BY THE "I" ICON), AND THIS STICKY. IF IT'S APPARENT YOU HAVEN'T, YOUR POST/COMMENT WILL BE DELETED.

WHEN ASKING FOR HELP YOU ARE EXPECTED TO INCLUDE THE FOLLOWING MINIMUM INFORMATION:

1. A BRIEF ONE LINE SYNOPSIS OF WHAT YOU'RE TRYING TO ACHIEVE.

2. THE RESULTS YOU'RE GETTING, INCLUDING ANY ERROR MESSAGES, AND AN ACCURATE DESCRIPTION OF WHERE IT IS FAILING. IN THE CASE OF THE LATTER E.G. I PRESS ESC, BUT THE BOOT MENU DOESN'T APPEAR AND IT JUST SAYS "BOOTING FROM HARD-DISK ..."

3. THE FULL MODEL NAME AND NUMBER.

4. IF USING SEABIOS, THE VERSION STRING REPORTED BY SEABIOS WHEN SEABIOS RUNS.

ALSO NOTE, I GENERALLY IGNORE PM'S/INVITATIONS.

THE BASIC PROCEDURE FOR GETTING SOUND WORKING ON BAYTRAIL DEVICES, ON LINUX, IS AS FOLLOWS:

1. UPDATE TO AT LEAST KERNEL 4.x

2. IF YOU'RE MISSING THESE THREE FILES FROM /lib/firmware/intel

fw_sst_0f28.bin
fw_sst_0f28.bin-48kHz_i2s_master
fw_sst_22a8.bin

DOWNLOAD THEM FROM https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/intel INTO /lib/firmware/intel AND REBOOT

3. RUN 'amixer -c 0 sset "Left Speaker Mixer Left DAC" unmute' AND 'amixer -c 0 sset "Right Speaker Mixer Right DAC" unmute'

N.B. YOU MAY NEED TO SOURCE FIRMWARE FOR THE SOUNDCARD AS AT LEAST ONE DISTRO IS NOT DISTRIBUTING IT.

I AM NOT HERE TO TEACH PEOPLE LINUX. IF YOU DON'T KNOW HOW TO USE THE LINUX CMDLINE, DON'T ASK ADVANCED QUESTIONS, OR AT LEAST COMPLETE THE LINUX FOUNDATION'S FREE "INTRO TO LINUX" COURSE BEFORE YOU POST.

Here's some instructions for installing Windows 8.1 or 10 on a Bay Trail chromebook: https://www.reddit.com/r/chrultrabook/comments/44hath/bay_trail_install_instructions_for_debugging/

NOTE: VERY PRELIMINARY SUPPORT. Please contact me once it's installed for debugging the rest of the devices on the system

It's got nothing to do with the directories.

All Broadwell based ChromeOS devices require a full firmware flash in order to run Windows. Also, Windows isn't supported here, see the link in the community info

If anyone here has a Toshiba Chromebook 2 (Gandof), a Raspberry PI and SOIC 8 clip, I have a new full coreboot ROM ready for testing. This will fix all graphics related issues, enable VT-x and allow installing Windows 8.1/10 or a Linux 3.19+ based distro.

+Ruben Rodriguez a Windows 8.1/10 compatible ROM for Dell Chromebook 13 is in the works but I need someone who has a Dell Chromebook 13, Raspi and SOIC 8 clip minimum. Having a beaglebone black as well would be a bonus as it'd make it a lot easier with EHCI debug.

Alternatively if I could get enough donations to acquire one, I could debug why the ROM I built for it doesn't work currently (It works on the similar Acer C740/C910 chromebooks)

Nope. I do fly by wire (and pants). The newer versions have better SD/eMMC support.

Due to me buggering about with cipher-suites in Nginx earlier in the day, you won't have been able to download the necessary files using the script, from ChromeOS.

I have since changed the script to use curl, which apparently doesn't suffer from an allergy to being forced to use TLS v1.2 under ChromeOS.

Normal service is resumed ...

Working here, too!  Thanks!
Though I agree with you, the wget display was cooler looking.  But most will only see it once, hopefully!

It's me again. I got a new SSD and now everything works but

Tried to install coreboot using the Arch Linux shell with your script but faced those errors:

Error accessing high tables, 0x10000 bytes at 0x7bf7a000
/dev/mem mmap failed: Resource temporarily unavailable
Failed getting access to coreboot high tables.

Is it secure to reboot? After this I tried to flash it again and got the same errors.

Hi I'm using c720 with windows 10 Thanks to john and CoolStar.

Recently, I bought HDMI - DVI Cable to connect my old monitor.
However, It won't recognize my monitor but connecting another monitor with hdmi - hdmi cable works properly.

I think this is driver-related issue. Has anyone solved this problem?

+Ted Phillips +Matt DeVillier HDCP is a non-issue here. HDCP is only required for protected content, not required by Windows 10 to show the desktop. I use HDMI->HDMI on a non-HDCP monitor just fine

Hello guys (and girls)!

Do ARM Chromebooks also use coreboot? I can't find information about that at all.

I got a Chromebook based on Rockchip RK3288 SoC. So it's an ARM.
I would like to replace Chrome OS with Gentoo Linux. I would be really happy when it then starts Gentoo even without "developer mode". Is that possible?
I have experience in putting Gentoo Linux on some other ARM devices, like Raspberry Pi, Odroid U3, Jetson TK1. But they use u-boot.

For now I know that on my Chromebook the Chrome OS kernel is flashed directly on a partition and has a specific GPT type.

+Martin Wohlert John Lewis has a good writeup on his site on recovering/reflashing a bricked Chromebook.  Typically you'll need a SOIC-8 chip clip and jumper wires to connect to the pi's GPIO pins

guys, how could I turn on caps lock on chrombook2 with xubuntu? I looked all over the place. The search+alt key combo no longer works. If someone has found this out, please let me know. I'm tired of pressing shift every time I need to type in capital letters

Hi,

I need some help, is there someone who has an acer c720 (P/N: NX.SHEEK.001)? If there is anyone who has such a chromebook I would like to ask them if it is possible to share with me their hardware id (hwid). The trouble is that after I restored my chromebook firmware the laptop has a wrong hwid.

This has to be the most noob question ever and I'm sorry, but I've looked around and cannot seem to find an answer...

I'm trying to install a custom ROM from John's website on my Toshiba Chromebook 2 (Swanky) and I don't know what to do with the command provided. He states to "Run the script like so, making sure you are only in Crosh shell not the root Crosh shell if running from ChromeOS" yet when I run the command in the Crosh shell I get an unknown command: cd error?

Thanks in advance,
Michael.

Thanks John, thought so too but for now it boots into Grub Safe mode everytime. No idea why. Any other Linux Distro boots fine

A newbie here.
Was reading on this article for the day if John or anybody could explain to me how this is working? So, what I have understand so far is that we are copying the files from kernel partition to the root partition(/) of Chrome OS, so that grub could boot up the system on its own. In my eMMC, there is 12 partition, which some of them are LABELLED as "BOOT-A","KERN-A", "BOOT-B","KERN-B", so my problem is that I don't know which pair to use. I might also have the wrong idea, so feel free to point me out.
My case: I decided to install linux(whatever distro, arch few hours ago) on an external SD card, leaving the eMMC untouched, so that I would not create any issue to the GPT layout in the eMMC.
The firmware flashing code was amazing, work magically in my case. And I can confirm that it will work on my HP Chromebook 14(aka003na)(or aka000-009 as shown on recovery utility) on BOOT_STUB approach.
You will need: A Chromebook, obviously (Haswell or Broadwell, although it may also work with older Chromebooks, doesn't seem to work with Baytrail); 2 or more USB sticks; An appropriate distro ISO. Please note – As a result of booting ChromeOS from SeaBIOS, the HWID is not available, ...

No. It won't work on Baytrail. Period. As I said above.
