Hi everybody!
I have one of those android sticks mainly for IPTV and games.
The device I have has a serious lack of WIFI, but no WIFI dongle that I have works out of the box.
Searched the internet in how to get the dongles working on Android, but I have the MK808C device that uses the AllWinner CPU so there aren't any custom roms.
No problem here, just bougth a ethernet USB adapter and it works without a problem.
In the last weeks I installed several flavours of linux using the wonderful Linux Deploy tool, and been playing with them.
I saw that I could compile the modules that I needed and ismod them. At least the wireless cards would work in linux, but no dice there either.
I got the drivers source from the internet, and when trying to compile it says that I do not have the linux-headers (and probably the linux-images):
Code:
[email protected]:~/RT3070_LinuxSTA_V2.3.0.1_20100208$ make
make -C tools
make[1]: Entering directory `/home/android/RT3070_LinuxSTA_V2.3.0.1_20100208/tools'

make -C /lib/modules/3.3.0/build SUBDIRS=/home/android/RT3070_LinuxSTA_V2.3.0.1_20100208/os/linux modules
make: *** /lib/modules/3.3.0/build: No such file or directory. Stop.
make: *** [LINUX] Error 2
I've been searching for the linux headers of my kernel version, but i've not been able to find it.
Code:
[email protected]:~$ uname -a
Linux localhost 3.3.0 #15 SMP PREEMPT Fri Dec 6 21:02:12 CST 2013 armv7l armv7l armv7l GNU/Linux
Again I cannot change the kernel version since there are no costum ROM's for my device.
Half of the searched that I make lead to this forum, but I cannot find a solution to my problem, so I decided to post this in hope that someone can help me.
Thank you.

For building own custom stuff for my Gen8 Device I set up an Ubuntu 10.10 32bit Virtual Machine, so everything in here refers to it, may be different on other linux system.
[disclaimer]This is only a HowTo, if you brick your android device with some custom kernels or other stuff, don't blame me! I'm not responsible for anything you do![/disclaimer]
Notice: ** = you only have to do this step once
Prerequisites for Ubuntu 10.10 32 Bit: **
Code:
# sudo apt-get install git-core flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl automake autoconf libtool gettext texinfo libmpfr1ldbl
Prepare environment: **
Code:
# mkdir -pv $HOME/{archos,bin}
# echo export ARCHOS=\$HOME/archos >> ~/.bashrc
# echo export PATH=\$HOME/bin:\$PATH >> ~/.bashrc
# cd $HOME/archos
# wget -Oavos_env.tgz http://archos-gen8-dvb.googlecode.com/files/avos_env_20110415.tgz
# tar xzf avos_env.tgz
# install -m755 cross $HOME/bin/
# rm -f cross avos_env.tgz
RESTART CONSOLE OR REBOOT COMPUTER!
Toolchain: **
Code:
# cd $ARCHOS
# make all
Configure kernel:
Code:
# cd $ARCHOS
# make kernel-config
Restore kernel config:
Code:
# cd $ARCHOS
# make kernel-reset
Build kernel:
Code:
# cd $ARCHOS
# make kernel-build
CrossCompile: (this is just an example for if you want to build some linux libraries or tools)
Code:
# echo $ARCHOS
# cd ..xyz../..zyx../
# cross make
I followed your instructions, and I got all the way to the end, but when I did 'make kernel-build' it ended with this:

This is on a fresh install of Ubuntu 10.10 32-bit in Virtualbox. I installed it, updated the OS, then started your steps. Not sure if this is normal and I'm holding off on the last step. I did do one extra step: in 'make kernal-config' I deselected all the Archos boards under System Type except for the A101IT since that's what I have.

I don't believe I changed anything besides what I mentioned earlier. Is there anyway to get back a default kernel-config?
hehe, I thought you should try with default kernel-config
I added a section for restoring kernel config in the start posting :

Well I did poke around in the config, but as far as I remember I only removed those extra archos systems. I'll restore the default and run it again later tonight.

You can't remove other devices (like A32, A101 etc) from Linux kernel config because Archos made bad dependencies for different parts of the kernel and even 70S requires some USB kernel code, it's only compiled when you choose A101 - so either you clean it up manually, or you are required to leave checked other archos devices :/
Thanks for this howto, this is gonna be useful for me, should be a sticky.
OK the make kernel-build worked without errors. Now I'm just questioning the command 'cd ..xyz../..zyx../' I don't have any files or directories called that, and running that reports the same. Can I just skip that and do the make cross?
@jbradshw that's just a sample if someone wants to crosscompile something (e.g. some linux library or application like linuxtv-dvb-apps or w_scan)
you don't have to do everything mentioned in the howto. it's a HowTo not a HaveTo
Ahh OK. So I guess I'm done then. I haven't installed the SDE on my Archos yet, but what's the final 'thing' that came out of this procedure that I'll be placing on the tablet?
Also I don't have an microSD card yet, and I know there was talk of putting stuff on there - can this be done using just the internal memory (8 GB for me)?
you have to install the SDE to install a custom kernel. follow this guide: http://forum.xda-developers.com/showthread.php?p=10157349#post10157349
Yeah I saw that guide, my question is where is the zImage and initramfs.cpio.gz that I assume was part of the compiling I just did? And also if a microSD card is needed for any of this?
no microsd is needed
initramfs.cpio.gz can be extracted from current installation ( /dev/mmcblk0p1 -> init ), read this: http://forum.xda-developers.com/showthread.php?t=880321&page=5
zImage is compiled at this location: $ARCHOS/gen8-gpl-froyo/buildroot/linux/arch/arm/boot/zImage
Shouldn't it be
Code:
cross make kernel-build
?
Here I have to use cross, which makes sense to find gcc arm binaries.
No you don't. In case of building stuff which comes with the gen8-gpl-froyo.tgz (e.g. kernel) the env vars are set up by the supplied makefiles

If I don't use cross, here is what I get:

make -C gen8-gpl-froyo/linux mrproper
make[1]: arm-linux-gcc: Command not found
make[1]: Entering directory `/home/ubuntu/archos/gen8-gpl-froyo/linux'
make[3]: arm-linux-gcc: Command not found
But using cross it compiled fine, though I followed carefully your directions !
Apparently I was too frightened by the error messages, since it does work in the end
Thank you very much, hope some good things come from this !
Cheers !

Yeah it's just an annoying bug, it doesn't hurt because "mrproper" only cleans the build directory and doesn't need compiler at all
2.6.29 kernel for Froyo?
Does anybody know, why Archos releases the SDK with a 2.6.29 kernel?
Shouldn't 2.2 Froyo be a 2.6.32 kernel?
Ok, I setup my 2 build boxes. One Ubuntu 11.10x64 and one Mint 11x86. Installed required packages and downloaded multiple toolchains. I have tried compiling on both machines and on both I get the same errors.

I have tried make thunderc_perf_defconfig and get the same error. Copied .config from device dropped into source, same error.
Any ideas on what is going on? I'm new to this so any help would be great.
I don't known, maybe gcc
try checking your mount options?
Nope its not gcc; as I said I have installed all required packages including gcc + bison etc. My mount options? Is that the "export ARCH=arm" ? Where I have to set the default compiler? I'm new to the newer flavors of linux. The last distro I used was Mandrake 7.1 ;-) Now I am testing this on 2 builds; an x64 Ubuntu and a x86 Mint(Which is Ubuntu). I have to be missing something on both, but I have followed tutorials guides to the T and still get this error. I get more errors than this by the way. The compiler kicks back Kconfig saying unexpected line of code.

I ran a search on your error message about the missing rule to make auto.conf and found this:
https://bbs.archlinux.org/viewtopic.php?id=99089
It relates to the other poster's comment about checking your mount options. It's a short process to fix it.
And if it doesn't work maybe it will at least give you a new error message to research.

Wrong...
Because you don't have .config file in the source. If you are building kernel from source, you must have the kernel config. That kernel config can be shared in the source code, it depends on that kernel developer, he can shared it in arch/arm/config, access to there then find that kernel defconfig. Or you can get the kernel config of that kernel with another method, but this method just can be applied if the kernel you want to build is for our device: flash that kernel then go to terminal then type:
Code:
su
(Accept the super user)
Code:
cp /proc/config.gz /sdcard
If it show "No such file or directory found" so you should ask that kernel developer for their .config.
If it doesn't show anything, go to sdcard and find if there is a file that named config.gz, it's the kernel config. Get back to terminal then type:
cd /sdcard
gunzip config.gz
Voila!
I actually tried that already.... I have been at this for about three days. XDA was my last resort as I like to figure things out on my own. However I'm stuck @ a brick wall. I have edited /etc/fstab and removed the bs mount options..remounted same error. Mind you I'm doing most of this from a Virtual Environment. Starting to think this is my issue, but it doesn't explain the same error on machine #2. Maybe I'm doing it right, possibly a bad git clone?

Yeah that would be great if I hadn't done that already. In my post I stated I had replaced the .config from my device. I have literately tried everything but doing this from base. IE not from a VM. I appreciate the help but its a "no go".

He isn't building ROM from source. He is learning how to build a kernel from source.
Sorry for the delay; had 2 deaths in the family.
I setup my third box and again I get the same results. I really don't know where I'm going wrong. This kinda makes me lean to, I have bad source code. I'm no pro C programmer; however when building I get Kconfig errors. I opened said file and the comments look all messed up. The compiler I think is reading the comments as code and kicking it back giving me this error.
by the way what are you compiling and please teach me compiling i want to learn it .
I'm compiling a modified kernel for the Optimus V. I can't teach you how to compile because I don't even know if I'm doing it right.
Ola!
This is my first post on this forum and I would like to thanks the moderators for the quality and organization of the information posted on this Forum.
My Phone:
Galaxy S3
Android 4.0.4
Kernel: 3.0.15
Base: I9300UBLF2
Problem:
When I try to mount a network path I receive one message saying that device does not exist, after reading some posts and googleing on this subject, I find out that I would need to load cifs.ko module. I tried a some versions that I foung on Internet but everyone that I tried replied this erros:
[email protected]:/sdcard/Bluetooth # insmod cifs.ko
insmod: init_module 'cifs.ko' failed (Exec format error)
I believe that this is because I would need one compilation for my kernel, am I right? Does anyone can help me to find the correct compilation for my phone or even more, help me with instructions to compile it on the phone?
Thanks and I appreciate your help!

I need help guys, I'm really new to this kernel compiling thing (I'm not really even a software engineer..) But anyway, so I have this mini wireless keyboard + mouse I'm trying to get to work on my MK802 II (Allwinner A10). From plugging the wireless dongle into my linux machine, I did an lsmod and determined the drivers to be hid-ortek.ko. And this driver happens to be absent on the MK802 II.
I set up my ubuntu with android sdk and ndk and all the other prereqs from thousands of other sites from googling.
Then I git cloned the Allwinner A10 kernel source from : https://github.com/amery/linux-allwinner and checked out the lichee 3.0.8+ to match the kernel version on my MK802 II.
So then I started off with:
Code:
make ARCH=arm sun4i_defconfig
make ARCH=arm menuconfig
And then I selected Ortek keyboard drivers from the UI and marked it as 'm'.
Because apparently Module.symver is only generated if you do a complete kernel build.. so I did
Code:
make ARCH=arm CROSS_COMPILE=~/Downloads/android-ndk-r8b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi- all
And Module.symver is created after this step.
But I looked in the ./drivers/hid folder to see if hid-ortek.ko was compiled and apparently not
so then I did:
Code:
make ARCH=arm CROSS_COMPILE=~/Downloads/android-ndk-r8b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi- M=./drivers/hid modules
And my "hid-ortek.ko" was still not created. The output from this was:
Code:
Building modules, stage 2.
MODPOST 0 modules
So I googled up tutorials and created a Makefile that looked like this:
Code:
VERSION = 3
PATCHLEVEL = 0
SUBLEVEL = 8
EXTRAVERSION =
obj-m += hid-ortek.o
KDIR=~/Documents/linux-allwinner
PWD := $(pwd)
default:
make -C $(KDIR) ARCH=arm CROSS_COMPILE=~/Downloads/android-ndk-r8b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi- SUBDIRS=$(PWD) modules
clean:
make -C $(KDIR) ARCH=arm CROSS_COMPILE=~/Downloads/android-ndk-r8b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi- SUBDIRS=$(PWD) clean
and did a make, that did the trick and hid-ortek.ko was created
So I did the adb push into my MK802 (into /system/vendor/modules folder) and tried insmod it.. but I kept getting
Code:
insmod: init_module 'hid-ortek.ko' failed (Exec format error)
and dmesg tells me that there is "no symbol version for module_layout". Which according to googling around means that Module.symver wasn't generated so I have to do a full build, but I did and I saw Module.symver generated in my kernel source directory. I did a modinfo on the compiled hid-ortek.ko and it shows
Code:
3.0.8+ preempt mod_unload modversions ARMv7
Which should be right. I did a modinfo on the other modules already loaded on the device and shows the exact same thing.
What am I doing wrong here? Please help.
Thanks!

Im buiding kernel for goodix touch drivers as im currently modding a LY-F1 JB ROM which uses a focaltouch touchscreen. but a full build is not enabling the modules and gives a exec error. Maybe it has something to do with ur extra version variable. change EXTRAVERSION = to "EXTRAVERSION =+" and do a build and tell me what happens. Im out so cant really test it.

Thanks for the reply, but that tablet has crashed and gone now. I will bear that in mind for the future...
I am not sure if this is the right place to ask, so apologies from me if not.
What works (at the moment, I cannot post links, so I spare out the details):
a) I managed to root my acer a3-a20fhd with the help of a windows version of kingoroot.
b) Secondly I finally chrooted successfully into an archlinux armv7-image from archlinux
c) So I could update, install and run xfce-desktop with the help of vncserver and a vcn-client from google's playstore (there are some left even the device is stuck to android 4.4.2).
I wondered if there is a way to add kexec support to the native kernel and then run the linux environment directly on the tab by firing up kexec from the chroot environment.
But I am stuck, is this possible at all?
Following the guide "Building Your First Kernel" from this forum and using the kernel sources from the website of acer, the best I can get is:
Code:
export CROSS_COMPILE="/mnt/sda9/ProjectX/archlinux/acer-a3-a20FHD/toolchain/bin/arm-eabi-"
export ARCH=arm && export SUBARCH=arm
cd /mnt/sda9/ProjectX/archlinux/acer-a3-a20FHD/acer.com/work/kernel/
make menuconfig
