Just saw some interest for Fedora install on Nook in another thread to my surprise. I thought I am the only pervert interested.
Anyway this is pretty raw at the moment. You need to know your way around Linux and have a Linux box (naturally).
Just not to disappoint you later on, here's what not working:
Only based on Fedora13 from upstream (F14 work is ongoing by Fedora-Arm team and I am just tracking them).
Wifi (still did not get to look into it)
BT (same)
accelerated graphics
Don't know of any touch-friendly WM, so defaults to Gnome.
Multitouch (disabled in driver at the moment since no userspace support anyway).
backlight control does not work, need to rewrite the kernel driver
Xorg does not know what to do with accelerometer input.
Probably tons of other things I forgot about.
You must be out of your mind if you want to try it on a tablet at this stage. Or just super curious.
You will need a microSD (at least 2G) card that you can dedicate to this.
Instructions:
Get "base" fedora sdcard image: http://nook.handhelds.ru/fedora/fedora-sdcard-v0.1.img.gz
Get base Fedora 13 beta3 rootfs: http://lists.fedoraproject.org/pipermail/arm/2011-May/001271.html
Get kernel modules for the kernel: http://nook.handhelds.ru/fedora/modules-2.6.32.9-fc13.tar.bz2
Unzip the base sdcard image and write it to your sdcard with dd.
run fdisk on the sdcard and add another partition covering the rest of sdcard in addition to the one already there. Write changes
do mkfs.ext4 /dev/yoursdcard2 (basically format the second partition you just created as ext4)
mount the /dev/yoursdcard2 somewhere as root (/mnt/somewhere later on)
untar the F13-beta3 rootfs to the /mnt/somewhere
Now you are almost ready, just need to fill some configs.
Edit /mnt/somewhere/etc/sysconfig/network-scripts/ifcfg-usb0 and add this there:
Code:
DEVICE=usb0
#BOOTPROTO=dhcp
BROADCAST=192.168.2.255
IPADDR=192.168.2.2
NETMASK=192.168.2.0
NETWORK=192.168.2.0
GATEWAY=192.168.2.1
ONBOOT=yes
Edit /mnt/somewhere/etc/resolv.conf and change "nameserver" there to 8.8.8.8
Add multitouch config in /mnt/somewhere/etc/X11/xorg.conf.d/touchscreen.conf
Code:
Section "InputClass"
Identifier "touchscreen"
MatchIsTouchScreen "on"
MatchProduct "cyttsp-i2c"
Driver "mtev"
Option "SendCoreEvents" "On"
Option "SwapAxes" "true"
Option "InvertY" "true"
EndSection
cd /mnt/somewhere/lib/modules and untar the modules file there.
umount /mnt/somewhere
Ok, now you are ready to do some stuff on the nook.
Insert your sdcard into the nook and boot it. You'll see Fedora text console. The installation is pretty basic.
Plug the nook into your Linux PC usb port. It should see a new network device
On the linux PC as root execute: ifconfig usb0 192.168.2.1 netmask 255.255.255.0
Enable ip forwarding on your host if you have it disabled (typically in /etc/sysctl.conf, the setting is ...ip_forward, make it =1. Run sysctl -p for the changes to make effect.
Enable internet access to internet for your nook via IP masquerading: iptables -t nat -I POSTROUTING -s 192.168.2.2 -j MASQUERADE ; iptables -I FORWARD -s 192.168.2.2 -j ACCEPT ; iptables -I FORWARD -d 192.168.2.2 -j ACCEPT
Now use ssh to login to your Nook: slogin [email protected] the root password is "fedoraarm" (no quotes)
Once logged into the nook, time to install some packages.
rpm -Uvh http://hongkong.proximity.on.ca/yum/base/12/arm/fake-kernel-provides-1.0.0-0.fc12.armv5tel.rpm
update the system: yum update ; yum install tar openssh-clients
Install the gnome environment: yum groupinstall 'GNOME Desktop Environment' --skip-broken
The gnome installation will take a while and will download everything from the net.
Now install the multitouch Xorg driver, get it at http://nook.handhelds.ru./fedora/xf86-input-mtev-0.1.12-1.armv5tel.rpm
Ok. Now you are ready to go. Run "startx &" and the Gnome will start on the nook. You can play with it a bit, use your finger as the mouse pointer.
You can add startx & at the end of e.g. /etc/init.d/rc.local to make it start on system startup or you can do it in a more pretty way.
There are some virtual keyboards in the repo. I tried gko and it sucks.
the "onboard" seems to be the one working best for me. "xvkbd" is a bit hard to operate.
The best one of them all is fvkbd, but it needs libfakekey missing from the repo, grab it at http://arm.koji.fedoraproject.org/p...3/armv5tel/libfakekey-0.1-6.fc13.armv5tel.rpm
Enjoy.
Fedora-arm homepage: http://fedoraproject.org/wiki/Architectures/ARM
I intend to include all the missing pieces into the fedora repo so that you don't need to install all those extra things. Also eventually I plan to add more hardware support and then hopefully migrate to a much newer kernel.
Ha, cool. Glad to see that not everyone thinks that only Ubootoo should be thrown on devices. I'll give this a twiddle for fun.
13 had Moblin, I wonder if that's any better for touch input..
Now i don't feel near as silly for working on my gentoo install for the nook!
Nice, I am still waiting on OpenSuSe
Why not try using Gnome 3? I just poked around in Fedora 15 today and saw the new UI, and I loved it. Bigger buttons, launcher dock, etc. Give it a look!

Fedora15 is not available for arm arch yet. But there is some work in that direction. So sure, once it's available I'd give it a try.
Great stuff here. I knows its early development, but fun none the less to see what our nooks can do.
And thanks verygreen for all your developments lately

No "gnome-shell" package in Fedora-arm repo at this moment,
Quite excited to see some work in bringing Fedora to the Nook Color! I <3 Fedora.
I just wish ARM had the same support as the full Fedora. Or that they would skip releases for Fedora ARM and go yearly... aka, skip to 15 next, then 17.
Could this be used to help port Ubuntu Touch?

Click to expand...
Click to collapse
No, Ubuntu Touch is based on CM and has very little in common with a full Linux port.
(This is not nessesary for MAC but you can have this for further use later,
In general you will need:
Python 2.4 -- 2.7, which you can download from python.org.
JDK 6 if you wish to build Gingerbread or newer; JDK 5 for Froyo or older. You can download both from java.sun.com.
Git 1.7 or newer. You can find it at git-scm.com)
Setting up a Mac OS X build environment
To build the Android files in a Mac OS environment, you need an Intel/x86 machine running MacOS 10.6 (Snow Leopard).
Android must be built on a case-sensitive file system because the sources contain files that differ only in case. We recommend that you build Android on a partition that has been formatted with the journaled file system HFS+. HFS+ is required to successfully build Mac OS applications such as the Android Emulator for OS X.
Creating a case sensitive disk image
If you want to avoid partitioning/formatting your hard drive, you can use a case-sensitive disk image instead. To create the image, launch Disk Utility and select "New Image". A size of 25GB is the minimum to complete the build, larger numbers are more future-proof. Using sparse images saves space while allowing to grow later as the need arises. Be sure to select "case sensitive, journaled" as the volume format.
You can also create it from a shell with the following command:
# hdiutil create -type SPARSE -fs 'Case-sensitive Journaled HFS+' -size 40g ~/android.dmg
This will create a .dmg (or possibly a .dmg.sparsefile) file which, once mounted, acts as a drive with the required formatting for Android development. For a disk image named "android.dmg" stored in your home directory, you can add the following to your ~/.bash_profile to mount the image when you execute "mountAndroid":
# mount the android file image
function mountAndroid { hdiutil attach ~/android.dmg -mountpoint /Volumes/android; }
Once mounted, you'll do all your work in the "android" volume. You can eject it (unmount it) just like you would with an external drive.
Installing required packages
Install XCode from the Apple developer site http://developer.apple.com/. We recommend version 3.1.4 or newer, i.e. gcc 4.2. Version 4.x could cause difficulties. If you are not already registered as an Apple developer, you will have to create an Apple ID in order to download.
Install MacPorts from macports.org.
Note: Make sure that /opt/local/bin appears in your path BEFORE /usr/bin. If not, add
export PATH=/opt/local/bin:$PATH
to your ~/.bash_profile.
Get make, git, and GPG packages from MacPorts:
$ POSIXLY_CORRECT=1 sudo port install gmake libsdl git-core gnupg
If using Mac OS 10.4, also install bison:
$ POSIXLY_CORRECT=1 sudo port install bison
Reverting from make 3.82
There is a bug in gmake 3.82 that prevents android from building. You can install version 3.81 using MacPorts by taking the following steps:
Edit /opt/local/etc/macports/sources.conf and add a line that says
file:///Users/Shared/dports
above the rsync line. Then create this directory:
$ mkdir /Users/Shared/dports
In the new dports directory, run
$ svn co --revision 50980 http://svn.macports.org/repository/macports/trunk/dports/devel/gmake/ devel/gmake/
Create a port index for your new local repository:
$ portindex /Users/Shared/dports
Finally, install the old version of gmake with
$ sudo port install gmake @3.81
Setting a file descriptor limit
On MacOS the default limit on the number of simultaneous file descriptors open is too low and a highly parallel build process may exceed this limit.
To increase the cap, add the following lines to your ~/.bash_profile:
# set the number of open files to be 1024
ulimit -S -n 1024
Next: Download the source
Your build environment is good to go! Proceed to downloading the source....
Why you posted this? It can be found on android's website. Also,you didn't post the whole tutorial.
why not simply install VirtualBox vor Mac and install a VM within?
...sometimes the life is complicated^^
@SWEATTAIMI did you actually manage to get a fully working build on mac? And if yes which version of OS X?
I've tried many times on OS X 10.7 and eventually ended up installing ubuntu on a separate partition...
secondary partition? what about the users here?
i use a VM on a small **** x86 notebook and can do all the development work + complete compiling. i thought a mac has much better hardware^^
I used to have ubuntu installed in vmware too but compiling took too long and it was really annoying. I rather prefer it this way... No shared resources

where could i found hping for android?
or where could i found busybox that contain hping?
What is the best forum for android busybox Q&A ?
Where can i tell my Android BusyBOX Question about HPING in busybox ?
Does anyone can help me ?!
busybox (busybox.net) does not include hping. You may find other multi-binaries including the hping, but it's not busybox and not very likely ported to Android. If it's hping you want, look for it (or port yourself) for Android - do not look for a "busybox". As long you don't need the tcl support in hping, I guess it's quite easy to compile it for Android.

Using the SDK plus NDK would be the easiest way, I guess, but since you are asking, I guess you are not familiar with porting code to the Android, and in this case, I guess it may be a little to large task.

This is possible because I'm running a complete GNU/Linux (Debian) on top of Android on it. You'll find a description with the how-to it in my signature, but it's not for the faint hearted and only for the GNU/Linux hackers, I guess. I don't know if this is easier than porting hping3 to Android, it's up to you to decide. But it really makes it easier running non-Android code, such as hping.
The XDA thread about it is here: http://forum.xda-developers.com/showthread.php?t=1780378
This is good idea but have 2 notes ! :
The virtual machines don't have a good packet throuput per secound !
And secound is i must install hping 3 whenever i run my VM !
I search for hping that i run it without in VM . ( because of low Packet Per Secound )

I'm sorry, but I've must have made myself unclear here. No virtual machine is involved here at all, no performance loss and no need to install hping3 more than once. What I describes is a runtime environment, and involves no emulation or virtualization.
Still, I do agree with you, the best solution for you is probably a hping3 compiled for the native Android runtime environment. Running Debian may be overkill.
I am thinking of starting a new thread to solve the issue of ArnoldTheBat r72 booting to blank screen on Acer Chromebook C720P
oops I just did -
Building Chromium/Chrome OS r71 or r72 Kernel RFC
It seems the only way to tackle drivers issues is to build the Kernel.
So, trying to build a Chrome OS r72 Kernel to use on ATB r72 to address these drivers issues, particularly the inability to boot Acer Chromebook C720P -
As I have never done this before, I need some pointers as documentation for this is very sketchy on Google groups. RFC alesimula...
What I have available is Ubuntu Bionic, & necessary storage to build (over 100 GB) -
I also have a chromefied Nocturne then eve 73/swtpm.tar SSD (on top of ABT r72) with Bionic crouton with same over 100 GB storage available.
First steps to build Kernel
Build chrome os kernel and kernel modules
In a Chrome OS box (like Nocturne r71 with kernel 4.14) - install crouton Bionic
$ sudo sh ~/Downloads/crouton -r bionic -t xfce,xiwi,touch,extension,keyboard,cli-extra,chromium
after installation enter chroot
$ sudo enter-chroot
$ sudo apt-get install git-core make kernel-package bc nano
$ git clone https://chromium.googlesource.com/chromiumos/third_party/kernel -b chromeos-4.14
TBC after download
adapted from https://github.com/dnschneid/crouton/wiki/Build-chrome-os-kernel-and-kernel-modules
Kernel download Chrome OS Kernel 4.14
After issuing the git clone command - I received some errors...
such as
error: RPC failed; curl 56 GnuTLS recv error (-54): Error in the pull function.
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
...
& after several tries succeeded with the message:
remote: Sending approximately 2.11 GiB ...
remote: Counting objects: 24648, done
remote: Total 7215674 (delta 5927776), reused 7215674 (delta 5927776)
Receiving objects: 100% (7215674/7215674), 2.10 GiB | 1.59 MiB/s, done.
Resolving deltas: 100% (5927776/5927776), done.
Checking out files: 100% (62736/62736), done.
So now the next business after securing the source code is to compile the kernel adding the modules/drivers needed to resolve issues such as camera & graphics, etc.
Hopefully this info is in here too
https://github.com/dnschneid/crouton/wiki/Build-chrome-os-kernel-and-kernel-modules
I am using Acer Iconia W700 with chromefied nocturne on top of arnoldthebat r72...
crouton bionic with xfce4 is my chroot environment to compile the kernel...
I guess I need to dig in, get the proper commands, it should not be different from compiling other Kernels for Android, Ubuntu, Arch Linux...
What I know is that it takes time...
hopefully if I get drivers, it will be worth the effort

Improving Kernel 4.14.83 from ATB v72 Methodology
Methodology
Extract base.config from FydeOS 5.3.1 (Chromium OS v70) & merge in its settings into base.config extracted from ATB Chromium OS v72...
Busy doing this, as I am not good at coding, so cannot devise an automated script, doing it manually is a long bummer
My comment in Telegram, frustration included -
Modifying kernel basic.config of ATB v72 to incorporate all settings/modules of FydeOS 5.31 (v70) is so tedious, it's a nightmare - I wish there was a way to automate this with a script that merges in FydeOS basic.config entries that are not present in ATB v72 - I am crap at coding & scripting, so doing it manually, it takes forever, & I keep making mistakes :stuck_out_tongue_closed_eyes: - as I am not sure what stops ATB v72 Acer C720P from booting, I have to include all missing settings in basic.config before building the kernel.
Chrome OS Kernel 4.14.96 built with extra modules for ATB v72
It does generate .config after all as usual for Linux kernels - got some issues from enter-chroot - had to do it from Ubuntu bionic proper with (from kernel source folder):
$ sh ./chromeos/scripts/prepareconfig chromeos-intel-pineview
$ make oldconfig
$ make -j4
Just now...
Finished compiling Chrome OS 4.14.96 for ATB v72 (which has Kernel 4.14.83), got vmlinux & modules - now need to find out how to deploy them on a Chrome OS installation...
After some struggle, managed to boot the new kernel as 4.14.96-09859-ga5c3f2f0428a-dirty
installed extra modules
by doing in crosh shell (not chroot)
in kernel compiled source code folder:
$ sudo make modules_install
it creates a new folder /lib/modules/4.14.96-09859-ga5c3f2f0428a-dirty
to get the kernel I just overwrite vmlinuz.A in /dev/sdb12 by kernel/arch/x86/boot/bzImage
(backup vmlinuz.A as vmlinuz.C)
to get to this:
$ mkdir efi
$ sudo mount /dev/sdb12 efi
$ cd efi
$ cd syslinux
$ sudo cp vmlinuz.A vmlinuz.C
$ sudo cp bzImage vmlinuz.A
../..
It boots great on Acer Iconia W700 & MacBook Air mid-2011
the joke is despite modules still no WiFi & no trackpad for MacBook Air
other joke does not boot Acer Chromebook C720P
well at least I tinkered with building this darn Chrome OS kernel - not much documentation on it (apart from how to do this in arm architecture)

As I do not know how to proceed from this due to lack of Google documentation - I will stop.
I think to get it working, I need to install Chromium OS from scratch, but documentation is unclear, & arnoldthebat has no instructions on how to do this.
So I am starting an effort to build a full Chromium OS from scratch - as
the best way to learn is to share know how.

Not exactly... always something
Installing Chrome OS Kernel 4.1.4.96 removes crostini, wonder why that is...
solution might be flags - as new kernel, some flags might have been lost
chrome://flags
will check
crostini already there - must be some settings lost with new kernel, or dependencies unmet
NB - all previous commands presuppose you have r/w privilege as root, i.e. issue:
$ sudo mount -o remount,rw /
$ sudo mount -o remount,exec /mnt/stateful_partition
Note - my gripe after all this is that drivers I needed do not seem to load, or I did not select the proper entries in base.config / .config
What's the point of building a kernel if modules cannot be loaded
Google Chrome OS is well protected, & Chromium OS does not seem to bypass kernel protection.

Methodology
Extract base.config from FydeOS 5.3.1 (Chromium OS v70) & merge in its settings into base.config extracted from ATB Chromium OS v72...
Busy doing this, as I am not good at coding, so cannot devise an automated script, doing it manually is a long bummer
My comment in Telegram, frustration included -
Modifying kernel basic.config of ATB v72 to incorporate all settings/modules of FydeOS 5.31 (v70) is so tedious, it's a nightmare - I wish there was a way to automate this with a script that merges in FydeOS basic.config entries that are not present in ATB v72 - I am crap at coding & scripting, so doing it manually, it takes forever, & I keep making mistakes :stuck_out_tongue_closed_eyes: - as I am not sure what stops ATB v72 Acer C720P from booting, I have to include all missing settings in basic.config before building the kernel.

Here is the dropbox link
[dropbox.com/s/esr407ybr5tev1u/configs.zip?dl=0](https://www.dropbox.com/s/esr407ybr5tev1u/configs.zip?dl=0)
it has the FydeOS 5.3.1 base config I extracted & your ATB v72 which I merged Fydeos 5.3.1 entries into - it updates to 4.14.96 from your 4.14.83 (replace z.config by .config)
It does compile a kernel OK - I did this manually, still learning how to do it signed. As I said details in my XDA thread.
I added all LCD panels modules, maybe it will finally allow to boot Chromebook C720P to GUI.
Oddly, I lose crostini, maybe unsigned kernels do that.

You are welcome to improve on it - it builds, but modules I thought added did not work on MacBook Air nor graphics of Acer CB C720P

I show how to do it in a previous post - but you need to be in a running FydeOS box, same with ATB.
sudo modprobe configs; zless /proc/config.gz
cat /proc/config.gz | gunzip > ~/Downloads/base.config
.config for Acer CB C720P
Still no luck with Acer Chromebook C720P - tried several changes to .config with make menuconfig & manually - boots to a blank screen still
Fydeos 5.3.1 does not have this problem.
Also tried just the .config of FydeOS on its own, & strangely no luck - there must be something else -
will now try this
# Display Panels
CONFIG_DRM_PANEL_LVDS=y
scratch - learning about kernel blobs /dev/sdx2 & /dev/sdx4
Just building the kernel & forcing in vmlinuz.A in /dev/sdx12 syslinux using bzImage (& modules in /lib/modules)
is apparently not enough...
It seems I also need to generate a new blob for the kernel which is /dev/sdx2
From documentation -
https://chromium.googlesource.com/chromiumos/docs/+/master/kernel_faq.md
we have
Kernel Root
pair A /dev/sda2 /dev/sda3
pair B /dev/sda4 /dev/sda5
in my case (as installed to usb)
Kernel Root
pair A /dev/sdb2 /dev/sdb3
pair B /dev/sdb4 /dev/sdb5
Some pointers here:
https://groups.google.com/a/chromium.org/forum/#!topic/chromium-os-dev/zmaziTddu5E
Major learning curve for me here...
what I need to do is upgrade the Arnoldthebat kernel blob KERN-A (4.14.83) with a new one for the new kernel (4.14.96).
I would appreciate if someone knew how to do this - that might be the cause issue of losing crostini when loading the new 4.14.96 instead of the original ATB.v72 4.14.83 one.
Share knowledge if you know how to do this, thanks.
Cooking -
I just flashed FydeOS 5.3.1 ROOT-A /dev/sdx2 blob which is 16MB over ATB v72 ROOT-A /dev/sdx2 blob which is 64MB & it booted, might be the solution I was looking for...
FydeOS (v70) is more compatible than ATB (v72) for many things. If the blob is involved, then it could be good news, easier than producing a new blob from scratch (don't know how either).
If so, working on blobs is an addition to-do list for hacking Chrome OS.
Hello. I am really glad someone is trying to build and install a custom kernel for ChromiumOS, as it will help fix *many* compatibility issues as well as it will make possible to add support for some hardware and features (for instance, audio over Bluetooth doesn't work as of now because the support library needed for BlueZ isn't included).
My computer isn't working properly and I don't have much space to build the kernel by my own, but I can help with testing and research. If you could share the binaries online (maybe a Git with releases?), this would be great.
What I have found and read about kernel on ChromiumOS so far:
1. Official documentation, it explains about the partition pairs:
http://www.chromium.org/chromium-os/chromiumos-design-docs/disk-format
2. More info (I think you have it already) but I think it is outdated as "console=tty1" doesn't work anymore (ChromiumOS now uses Frecon):
https://chromium.googlesource.com/chromiumos/docs/+/master/kernel_faq.md
3. This is a nice repo, it explains a lot, specially about kernel modules (drivers):
https://github.com/dnschneid/crouton/wiki/Build-chrome-os-kernel-and-kernel-modules
From what I have used and tested, you can use GRIB to either boot from the vmlinuz.A/B image or use the partition with the kernel, using the partition is much complicated as you found out because it would need some blobs/keys.

Thanks for the resources, I am getting old, so rather hard to learn & deal with new stuff - tinkering OSes & software is a hobby for me, but I usually do test stuff, not create - I had nice experience with Hackintosh, before I owned my own Macbook Air, still use it from USB's & PC when needed.
So far, I find out blob does not improve matters, it just gets used, like above blob from ATB or FydeOS does same thing.
The way I started in this was just to get Acer Chromebook C720P to load Android, chromefy carried on better than where I started.
The most successful outcome for me is Acer Iconia W700 which works with eve 73 (leaked on Telegram)...
I have the resources to build the kernel - but it is not doing what I want, like booting ATB v72 in Acer CB C720P - it i not vital, C720P works well with FydeOS & cyan or eve 71, just a challenge - why is ATB v72 not booting properly - i's a graphics VESA or LVDS bios issue I believe (C720P board uses LVDS for graphics), but where does it get loaded, I believe it's before loading modules...
FydeOS 5.31 boots to a black screen on my Miix320 but I have to wait until it loads everything then I must hit Ctrl+Alt+F2 then go back to main screen and then it works properly thereafter. Is your Acer the one bellow? Maybe it's related?
http://www.chromebookspecs.com/acer-c720p-chromebook
By the other hand, I cannot enable clicking for the detachable touchpad (+keyboard), what is almost a dealbreaker... Neither it goes to tablet mode when I detach it from the keyboard (not a big deal).
By the other hand, it boots correctly on a ThinkPad 8 tablet, but if freezes after a few seconds unless I use acpi=off or noacpi as kernel parameters, what makes it usesless since it only detects USB hardware.
From the text I linked it seems that the extra data added to the kernel before flashing it to a disk partition is both its signature and kernel paramenters, so you may want to check if there is any special paramenter needed for the kernel to boot correctly on your C720P.
FydeOS base upgrading kernel from 4.14.67 to 4.14.96
Kernel 4.14.96 upgrade progress -
I allowed
CONFIG_TCG_VTPM_PROXY=m
in .config
& this allowed me to update a chromefied FydeOS with eve/caroline 71 to eve 73 dev by using chromefy2!
this in turn allowed me to use an edimax Wifi USB dongle in MacBook Air -
the onboard WiFi still not loading, no trackpad but still progress :relaxed:
so modules do get loaded unlike my concern, it's just a matter to identify the proper entry in .config to load them when compiling the kernel...
now what are the proper entries for internal WiFi & trackpad?
Extra - Icing on the cake -
FydeOS 5.3.1 with eve dev 73 - putting the correct files in place allows to load kernel 4.14.83 & its modules to get crostini -
of course loading FydeOS kernel which is 4.14.67 stops Android 9.
This amended chromefy.sh script might help with MacBooks for trackpad & WiFi.
https://github.com/youngyou/chromefy/blob/master/chromefy.sh
*** Important note ***
To install the kernel modules in the Chrome OS box, you need to install Chromebrew to have access to the necessary commands -
$ curl -Ls http://git.io/vddgY | bash
In kernel source code folder:
$ sudo make modules_install
then copy bzImage over vmlinuz.A (after backing up the original)
I am planning to release an archive with kernels & modules including the one I built, it will be
vmlinuz.A.67(4.14.67); vmlinuz.A.83 (4.14.83); vmlinuz.A.96 (4.14.96); & corresponding /lib/modules folder
FydeOS 5.3.1 - ATB v72 - my built kernel
Notes -
Kernel 4.14.96 upgrade progress - I allowed CONFIG_TCG_VTPM_PROXY=m so this allowed me to update a chromefied FydeOS to eve 73 dev by using chromefy2! this in turn allowed me to use an edimax Wifi USB dongle in MacBook Air - the onboard WiFi still not loading, no trackpad but still progress :relaxed:

Cool progress - I managed to boot to the GUI of Acer CB C720P with eve dev v73 - still need to iron out something, but could get into guest mode, & to linux prompt - this is great :stuck_out_tongue_winking_eye: this is using kernel 4.14.83 on top of FydeOS 5.3.1
Finally managed to log into my google account in Acer CB C720P- next hurdle, will Android 9 work? - crostini back in the menu -
hurdle - despite changing vmlinuz.A to 4.14.83 or 4.14.96 - it still only loads FydeOS 4.14.67
so
I learnt something new, which means I need to learn more -
when you boot to a real chromebook from usb or internal, it will look for the kernel in the blob KERN-A /dev/sdx2, & will not use the vmlinuz.A in /dev/sdx12 -
so with FydeOS stuck with kernel 4.14.67 -
if I boot from other laptop, blob is not used, vmlinuz.A instead -
so I need to produce new KERN-A /dev/sdx2 blob for new kernel,
FydeOS blob is 16MB, ATB v72 blob is 64MB,
so to flash I need to play with partitions, tricky, & did not work...
still didn't figure out how to make a new blob for a new kernel...
RFC - how to produce a blob for loading a new kernel?
RFC - how to produce a blob for loading a new kernel?
If there is a way to find out how to produce a blob of an updated kernel for a genuine vanilla chromebook such as Acer Chromebook C720P - I will post it here...
Google open source documentation is very confusing about this - it might also be generated when setting up a Chromium OS from scratch (my thread on this is halted for now, but I have all the setup foundation to build)...
What I gather is that vmlinuz.A is the kernel, but for chromebooks, the kernel is also contained in the blob which is in partition /dev/sdx2 labelled KERN-A -
so I need to produce an image kern-a.bin which I then flash to /dev/sdx2 - with FydeOS 5.3.1 the KERN-A blob contains Kernel 4.14.67, with ATB v72 Kernel 4.14.83...
the dilemma is that KERN-A size for FydeOS 5.3.1 is 16 MB & for ATB v72 it is 64MB, so I cannot flash the latter onto the former.
I need to find out how to create a 64MB image for KERN-A from a given kernel, such as ATB v72 or my compiled one which is 4.14.96 -
Anyone who has a clue, & better has the correct instructions to do so, please help...
Actually, you don't need to: you can use the compressed image with GRUB2, and it will boot using your system and state (data) partition.

Using a modified FydeOS 5.3.1 as base, no matter I change the kernel, it boots its own 4.14.67 kernel on Acer CB C720P - however using non chromebook devices such as macbook, allow me to boot vmlinuz.A & its associated /lib/modules/...
Care to share how to use grub2 to override the above?
