Hi all,
trying to get my feet wet with some android hacking and thought getting my AR.Drone to work with my legend would be a good start. It requires connecting to the ad-hoc network created by the drone. The normal way is to edit /system/etc/wifi/tiwlan.ini as described e.g. here: projects.ardrone.org/boards/1/topics/show/1098 but /system doesn't seem writable even though I have root. I then found this app for the desire: code.google.com/p/desire-adhoc/ but the legend has a different wifi chip, so it didn't work. Attempting to reproduce what that app does I did
$ adb shell
# su -c 'insmod /system/lib/modules/tiwlan_drv.ko'
insmod: init_module '/system/lib/modules/tiwlan_drv.ko' failed (No such file or directory)
even though that file definitely exists. Am I missing something here, or is that part of the annoying restrictions still present even on the rooted legend? Ad-hoc wifi must be possible somehow, the wifi-tether guys managed to get it to work. Unfortunately their code is a bit over my head. Any pointers?
thanks

Do it from recovery mode. We don't have access to /system in normal usage of phone (you get used to it).
okay, I guess I have to learn how to bake my own update.zip.
still curious though, why am I getting "no such file or directory" if it's clearly there (and a similar method seems to work on the desire)?
I also tried this:
forum.xda-developers.com/showthread.php?t=754961&highlight=legend
Which is a quite cleverly hacked wpa_supplicant, but that resulted in no wifi at all any more, even though the patched supplicant is officially the same version. strange.
any clue how the wifi-tether guys do it?
No, those command work. Boot your phone to recovery mode, then mount the /system partition from the ClockworkMOD menu. then you can execute your commands, they should do it.
Also, questions like this shouldn't really be in the development section. Just so you know.
You got it all wrong guys... first you dont need to su -c as you already are root. Second... you need to load sdio.ko prior to tiwlan_drv.ko. And no we do not perform these in recovery mode
I thought he was editing files... Oh well, I'll read more carefully in future. Sorry guys.
EDIT:
Yeah, look:
The normal way is to edit /system/etc/wifi/tiwlan.ini as described e.g. here: projects.ardrone.org/boards/1/topics/show/1098 but /system doesn't seem writable even though I have root.

So he could edit from recovery mode. But, I was still an idiot, I said to do the insmod things from recovery. I am very sorry for wasting time here, I'll learn to read carefully and give proper answers.
Sorry

aaaahhh, that got me a bit further thanks! very confusing error message...
so module loading works now, but the phone just reboots a few seconds after I set
"iwconfig tiwlan0 mode ad-hoc"
any further advice?
Also I guess the confusion was my own fault since I rolled three different ways of doing one thing into the same post...
Oh man, I've said all the wrong things today. I'm so sorry. I'll just leave this thread now.

Yes. Loading modules just isn't enough in our case. You need to load firmware too before you bring interface up otherwise your system will reboot
Check Gratiend ROM thread or look into init.legend.rc for hints on firmware loading...
thanks. found this
/system/bin/tiwlan_loader \
-f /system/etc/wifi/Fw1273_CHIP.bin -e /proc/calibration \
-i /system/etc/wifi/tiwlan.ini
after googling init.legend.rc. doesn't seem to make a difference though. also tried using tiwlan.ini from the wifi tether guys, but no luck. device still reboots after setting ad-hoc mode. I guess I give up, there's no-one answering to my question on the wifi-tether google group either. i guess just because it's open source doesn't mean it's for the uninitiated...
Try sleep for 1 or 2 seconds after you load firmware, then bring interface up or start wpa_supplicant.
I you are using patched wpa_supplicant I guess you will have one more obstacle. It supports only wext aware devices and I guess our driver is not wext aware...
I solved the problem by installing Cyanogenmod (all other tries failed)

I enter the commands by hand, so there's already a delay in between. And I'm doing this by hand precisely because the patched supplicant didn't work on the legend. I guess now I know why. Thanks for all the advice though.

I had a CM6 nightly installed and toyed around with it a bit, but I actually use my FM radio (I know, barely anyone else does...) so I need to use a HTC ROM. liked the CM6 in a lot of other respects though. still out of the question for now.
Also I would eventually like to contribute whatever comes out of this to a proper AR.drone app that requires root and nothing else.
Could someone compile the following file for me? I'd do it myself, but, unfortunately, I don't have access to a computer, nor will I for a while (I'm touchpad only for now).
https://github.com/CyanogenMod/hp-kernel-tenderloin/blob/gingerbread/drivers/net/usb/mcs7830.c
The driver is for a USB-Ethernet adapter that I'm trying to get working on the Touchpad through ICS (cm9).
Thanks.
Is this for USB 3g dongles??
No, not for a 3G adapter, but for one that goes from USB to Ethernet cable.
jcsullins compiled it for me, by the way, so I no longer need the driver (many thanks to him).
However, I can confirm that ICS on CM9 recognized it without problems as eth0 and once I ran dhcpd and assigned a DNS server, I had no problems connecting to the internet. So feel free to add a driver for your own adapter if you have one.
So to review:
-copy driver (to /system/lib/modules)
-insert module ("insmod /system/lib/modules/*yourdriver*.ko")
-get an IP address (manually, or "/system/bin/dhcpd eth0")
-add DNS (setprop net.dns1 *yourDNSserver*)
A couple caveats, I've noticed.
1) It doesn't play nice with wifi. I sort of expected this, but bringing up wlan0 and eth0 at the same time crashes the tablet.
2) Not all apps recognize the internet connection. This is a bit frustrating since most do (including the Browser), but not all.

I figured out how to compile drivers manually myself shortly after my posts in this thread. I havent used my build environment in a while though, should still be able to check out what (if any) drivers are built into the kernel by default. Do you already have an adapter?

OMG thank you for responding! No, I don't have an adapter yet--was waiting to find out which one works and I'll buy that. I'm open to suggestions. Thank you!
You are my shining beacon of hope ba114! Have you had a chance to see what drivers might exist in the kernel?
I read elsewhere that the cyanogenmod for the asus transformer contains a driver compatible with Asix AX88772. That chipset is what this cheapo adapter (OMG, no links for noobs!) uses. I have half a mind to buy one just to see, but it would help immensely if someone could confirm that jcsullins cm9 or cm10 for the touchpad also has support for this chipset baked in...
Hopefully giving you something to work with will make this less of a "needle in the haystack"...
Thanks!
really wish I could post links, as jscullins has posted the driver!

could use some help
OK, finally got my OTG cable and USB ethernet. Let's do this!
Tried to follow these instructions:
So to review:
-copy driver (to /system/lib/modules)
-insert module ("insmod /system/lib/modules/*yourdriver*.ko")
-get an IP address (manually, or "/system/bin/dhcpd eth0")
-add DNS (setprop net.dns1 *yourDNSserver*)
Had to troubleshoot why my Touchpad wasn't being seen as a USB mass storage device. DONE. I'm feeling like a boss.
Windows Explorer didn't see the main system--just the "SD Card". What ever--not big deal. I copied the driver over to the SD Card. Downloaded Astro File Manager to copy the file to /system/lib/modules. Nope. Denied.
No problem! Dropped to terminal and enabled super user. Astro is still a no go. No worries!! I'm a big boy--I'll do this in terminal! Taught myself enough command line jargon to navigate to the file, and copy it to the intended directory. NOPE. Directory is read only.
OK, so I navigate there and try to chmod the directory with u+w. "Bad mode". Research that to learn I have to use the numbers. So I try that (775) and now it tells me it is a read-only file system.
sigh
It might not seem like it, but I'm trying. I really am.
Can someone tell me how to get past step one of this process? Please? What on earth am I doing wrong?
I recently had to do some wizardry on my phone to get openvpn to co-operate, and I suspect that would work here but I don't understand the commands, and fear I'd end up screwing something up.
This was the command:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
I'm guessing I need to unmount the system so I can work on it and copy the file into that directory? Is that the case? Would the command line be the same, or different?
Anyone else get this to work now that the driver has been posted publicly?
Thanks!!!!
To help those who come after me:
Grab ES File Explorer. It includes a Root Explorer that lets you mount the file system as writable. The "copy to" command claimed to work but did not copy the file. Copy the driver, then manually navigate to /system/lib/modules and paste. Voila.

this took me a long time to figure out. as far as I can tell, the only "directions" noobs like me have to follow contain typos. the command should read dhcpcd eth0
HOWEVER, what I get instead is eth0: interface not found or invalid
a little help here? Does the mcs7830.ko driver work with the Asix AX88772 chipset?
Stupid question--should I be expecting the touchpad to power the USB ethernet adapter via the OTG cable, or do I require a "Y" cable to supply power? Is that why I'm getting:

I would assume so. Every HP Touchpad tutorial that I've see that mentions an OTG cable also mentions it needing to be powered.
Since we got a x86 cpu i want to use ubuntu on it, as im from germany i still dont have my I but has anybody tried linux on android?

Kernel version is 3.0.8.
If you can install linux distros on the backend of rooted ARM devices it should make sense we could do the same....maybe
Ubuntu on a RAZR I ? Linux x86 apps + windows apps with wine without even recompile? I think this devece needs some love. It can be the next HTC HD2 for shure.
I dont understand the htc comparison
But i have your ideas about no need to recompile and wine in mind too...
But i understand adam because linux for android is compiled for arm achitecture so a usual desktop image would make more sense...
Why is the kernel version so low?!

What we need to do
I have a friend with this device, after rooting he reports there is no chroot command from terminal. If so we must:
Compile busybox (with more extensions) for x86 and install it alongside root (or after root)
Make a mountable image from an ubuntu clean install and mount it (probably also needs busybox)
chroot into this mounted image
run a vnc X server on a framebuffer
vnc from android
This is how it is done on other android devices, will attempt to compile and try these instructions out this weekend when I meet him but booting native ubuntu is a much better idea (even better if we can make it receive calls ).
And for what Windows on 4,3 inches display? It dont have hdmi.

Go look up the HTC HD2. It can run Windows Phone 7 and Android dual-booted (with Linux from SDCard), and was originally the last, albeit most powerful, Windows Mobile 6 phone ever made.
Even though it is four years old, there is a massive and vibrant dev community behind it, making it reach the front page of XDA forums.
However, even the venerable HD2 is getting old, with 1GHz processor and half a gig of RAM that was top-of-the-line years ago, and people have looked in vain for some kind of successor. Hopefully, the Razr I, with an unlockable bootloader and Intel processor, will be the one. But that remains for us to do.

So I tried this out and there is a chroot-compatible busybox after rooting ("busybox chroot" needs to be called as opposed to "chroot" as there is no properly made link), so anyone with this phone can try (using a PC) install Ubuntu without the grub bootloader using manual partitioning on a single ext3 (I am not sure if ICS supports ext4) partition on a microsd, put into your phone, use a root terminal, mount it, mount the adequate dev, dev/pts, proc and sys partitions and chroot right in. You then might want to install a VNC server in Ubuntu to be able to create a VNC X session in a framebuffer and a VNC client on the android side to VNC into localhost (127.0.0.1), but that should work, I didn't have time to try it this weekend If someone gets stuck post and let us see what happens I cannot wait to see if wine can run desktop Spotify with sound, excited a little hehe.
EDIT: So to make this more understandable you must:
Install Ubuntu (using your computer) to a MicroSD, specifying partitions manually and choosing only a single ext3. Right before clicking install there is a button with something along the lines of "Advanced options", disable the install the bootloader (grub) option.
Insert the MicroSD into the phone and open a root terminal
I don't use Android, maybe it automounts in /media/sdcard or /sdcard, if not you will have to find the device and partition name (probably /dev/mmcblk0p1 or /dev/sdb1) and issue "mount /dev/DEVICEPARTITION /media/sdcard"
mount -t proc proc /media/sdcard/proc
mount -o bind /dev/ /media/sdcard/dev/
mount -t devpts devpts /media/sdcard/dev/pts
busybox chroot /media/sdcard /bin/bash
Now a shell from Ubuntu should open. apt-get update && apt-get install vncserver (maybe the DNS settings must be set in /etc/resolv.conf, not yet sure)
vncserver (or start vncserver, something along those lines)
Now from Android install a VNC viewer and vnc into 127.0.0.1 (or localhost)
That should do it, again if you get stuck post here
i had htc hd2, the most amazing phone in the world. I wanna buy the rarz i for the x86 processor in it. But cpu power without community and developers is nothing :|
Sorry for my bad english.
Yesterday we tried something:
We used dd to put an arch linux image on a micro sd card...
Though my laptop wasnt even able to boot from any sd card, this should work on our phone...
but how to make it boot from the sd card? xD
btw you might have noticed, this will make only linux boot, not android, we dont chroot, may somebody build a simple ubuntu img for complete linux installer?
//Robert
so right now i am trying to chroot into an img file, mounting it and then chrooting it but all i get is:
chroot: can't execute '/system/bin/sh': No such file or directory
whats wrong?

Hey,
great work. :good:
Good to see there are people with the same ideas. I´ve searched a lot for this thread.
I will also try to get this device for the same reasons when it´s cheaper. Has anybody tried to get Plasma Active or Tizen to run?
I think Active should now be possible through kubuntu Active?

Hi all
At first you can try a application from play store called Linux installer
https://play.google.com/store/apps/details?id=com.zpwebsites.linuxonandroid
Otherwise you can wait some weeks for an nexus 7 Ubuntu port witch looks really interesting.

thanks for your post on preparing an arch image (I don't have permision to post in devel forum, maybe because I'm a newbie ), It worked well for me although I had to adjust some things such as path and pts mount
I now have a gcc toolchain and a latex distrib on my phone I had never used arch, found it very good
I've also tried some window managers ... the one I find best for the moment is enlightenment in the touchscreen mode, awesome works great as well.
I would also suggest to use Hacker's keyboard instead of stock android, it is a complete keyboard, very usefull when dealing with terminals ... as for VNC viewer, one should recompile android-vnc-viewer with the patches given in Issues 238 and 239 (can't post links either), it's a lot better
I've had a lot of fun, thanks
First, Complete Linux Installer doesnt work because its images are compiled for arm not x86 (i tried )
Secondly, I did a tutorial here http://forum.xda-developers.com/showthread.php?t=1966984
the nexus 7 stuff is interesting and we consider making flashable fastboot for the razr i since we dont have cwm or such you know
i am talking to jordan keyes who recently owned a nexus 7 who probably will try out the ubu stuff and i might get some system info
but i would really prefer a dual boot, capable of booting from sd...

The bootloader won't boot directly from the sdcard.
Nevertheless, you can definitely have ROM images in the sdcard and use those while booting android (basically you only have to update init.rc for that).
Check 'multiboot' in my signature for more details.

S1loader is not open source to work with. You could hex-edit it if you had some easy way to flash it and recover from the countless hard bricks the bootloader development process has. Unfortunately this is doable via jtag only. My knowledge is limitted on that area.

As for the bootloader, what could be the first real-time editor hex can perform a large change in the machine switched on.
When it comes to dual boot I can help not only the development of a test.

not worried about the phone I'm always ready to purchase a new...
The idea of a modified bootloader is nice, but it have two problem.
1. Modify the bootloader to add capability to boot directly from sdcard is basically useless because this is possible with a simple script in a modified ramdisk. Check the post from nAa, or search the thread about nBoot from feherneoh. This is easy and not need to do dangerous things.
2. The modification of the bootloader is near impossible because:
- the working of S1Boot is not documented
- this is a non-standard raw binary, hard to disassembly/decompile
- if someone can disassembly it correctly, need VERY HIGH skills in native arm assembly programming
- need special hardwares to revive the dead phone after all failed modifications (special cables, setool, etc...)
Don't forget: we had to wait more than a year to get unlocked bootloader (and this modification only skip the security verification), and this is working only with devices what older than 1-1,5 years.
I think if someone have these prerequisites, better if he/she working on valuable things instead of boot from sdcard (add fastboot support to bootloader, etc...)
I was thinking of making nBoot work with JB (it didn't). If that fails we will come up with a new method.
It's almost impossible for us to re-write the bootloader.
It would be super cool if someone added fastboot support to our bootloaders.

maybe not in our device but its not impossible

Obviously I was talking about these devices not some Samsung one...
@sgt. meow fastboot support is not something that can be added to an existing bootloader. The bootloader itself has to support this protocol. Hence the only solution would be to switch to another bootloader which would have to be ported from scratch for these devices.
The job would require a tremendous amount of effort since not even miniloader works for them!
Can we use dd to write an entire directory to a .img file? I'm thinking of something.
@nAa
I know. I was just unaware that bootloaders could be ported for our device (even if it meant no sleep for 6 months for the brave dev).

Mtd devices are not block devices. What are you trying to achieve?

I was thinking of using feherneoh's nBoot, but in a different way. My idea was to somehow write the current ROM's /system to system.img on sdcard and the same thing with data and cache. Then install another ROM that uses the same kernel (JellySony for example). Then if XXX is present in /sdcard, it would mount system.img as /system (and the same with data and cache), thus enabling dual-boot. In a kinda stupid way.

This is how my multiboot mod worked actually - except from the fact that back in those days we couldn't flash custom kernels and the whole job was done via the chroot/hw_config.sh hack.
The bummer is you can't switch kernels so multiboot between say gb and jb is not possible.

S1loader is not open source to work with. You could hex-edit it if you had some easy way to flash it and recover from the countless hard bricks the bootloader development process has. Unfortunately this is doable via jtag only. My knowledge is limitted on that area.

There are two options:
- Export all the partitions (I think the file is nand_partitions.c) from kernel. The mtdump/dd it.
- Use the mtdmapper module that is in the unlocking bootloader tool to get all the partitions to map and then dump it.
Both ways basically do the same thing and they both have a pretty BIG chance of getting your device hard bricked (even when you are in read-only mode).

This is my first attempt at building an Android Kernel, last time I did it was for Ubuntu Gutsy, so please bear with me.
This is a stock AOSP kernel for Fugu, 3.10.20. All I did for now was a make menuconfig enabling some features I miss. I'm testing what I enabled, so far I've been able to mount an smb share from both windows 7 and my D-Link DNS-320 NAS running alt-f. Tried to mount nfs but it failed against my NAS. Haven't tested it yet with an NTFS formatted drive, will report back once I do. NFS mounting worked after I disabled SELinux enforcing, will try to figure what's needed to get it going without turning it off. I've been able to move apps to external storage using bind mounts over an ext2 formatted micro SD card, and on an NTFS formatted HD. This didn't work on a FAT formatted card, I'm mostly sure it's because of lack of extended attributes needed by SELinux.
All the features enabled on the kernel are built-in for now, but module loading is enabled in case you want to compile some.
I have a powered OTG USB hub, connected an old Microsoft MCE receiver and got the direction keys on the remote working, no other key worked, so I guess some kind of keymap is needed, will dig into it soon.
Also, I've built with support for my ISDB-T receiver (digital TV standard used in Japan and most of South America). It's seen by the kernel but fails to load firmware. My receiver is a Mygica S870, don't know how involved will be the process to get it working, it's not my main focus as I use it with a Raspberry Pi running tvheadend, but would be nice to get OTA tv on the nexus player with just an USB tuner. If you'd like me to add your tuner, let me know the HW / USB:ID.
For now, the kernel is provided as a zipped image, download, extract and test before flashing:
Code:
adb reboot bootloader
fastboot boot boot.kernelfox.img
If you decide to install it, you can do it with:
Code:
adb reboot bootloader
fastboot flash boot boot.kernelfox.img
or you can use TWRP to flash it. Remember, this is not an update zip, so you should copy the extracted .img file to your player (not the zip), and select Images... on TWRP to see it. There's a kernel.config file in the zip, it's what I used to build this one, if you want to try compiling it yourself, copy it as x86_64/.config on your git root.
I've been running it for the last few hours, but as my gf is using the player, I'm limited to testing from a remote adb. I'll be trying to build support for some type of unionfs for apps2sd, I'm evaluating the available options and would love suggestions about this, again, last time this was an issue for me was on the Motorola Milestone (ie Droid) days.

Since this is AOSP based, I'm assuming it won't work with CM?

I'm almost sure it shouldn't, but you can do a one time boot without flashing it, so I'd love to hear if it does. My player gets a lot of use here so I can't mess that much with it right now. I'm targeting rooted stock, as I really like it and would love it with just some tweaks.
@FaberfoX is this for 5.1.1

Yes, haven't had time to dig more into it, but I've been running it on LMY47V since I built it with no issues.
Thanks man going to flash it this week
