[Linux] [DEV] [WIP]Backtrack 5 on the gtablet HYBRID. 7/18/11 1.2 BL kernel
- Thread starter slimm609
- Start date
Read post 2 under the
************OLD WAY****************** section. This explains it.
pershoots gtab/zpad kernel works. The kernel must have loopback device support.
if /proc/config.gz exists you can check with
zcat -c /proc/config.gz | grep DEV_LOOP
and you should see
CONFIG_BLK_DEV_LOOP=y
Got the 4 side buttons to work with a bit of a C and bash hack. Just need to finish up a few things with the buttons then will try to work on sound for a bit and see what we can do with it. there should be a new version up on the main thread in the next few days.

Keep up the great work! I'm looking forward to this replacing android on my gtab!!
I have this running, I cannot login using the username "root" and password "toor" or "toortoor"
Going to have to hack a user into it to use it!

To correct the password error:
as the last thing in adb before you flash the kernel.
user: root
password: toor
Code:
cp /sdcard/etc/shadow- /sdcard/etc/shadow

user: root

Thanks slm4996
i fixed the bt5.tbz2 to correct the password issue and added a new kernel to flash with nvflash. touchscreen will be coming very soon. its a ton of deps and takes a while to update the image off the gtab.
Is the X11 hardware accelerated? Can we install any linux video players and have them do hardware decoding? What about any linux 3d apps, will they have opengl hardware acceleration? Is Flash 10.3 have hardware acceleration on linux or has flash not gone there yet?
Or are none of these things compiled into the kernel/X11 subsystem yet?

Would you be so kind as to release a kernel built with "root=/dev/mmcblk2p1" for those of us who want to use the external sdcard?
I can post that tonight. It is based off of pershoots kernel but the config is different. zcat /proc/config.gz if you want to see it before I get a chance to post it

Post one updated. with extsd kernel and added config. slm4996 let me know if you have any problems with the other kern.
there is no flash version for arm linux currently and i not sure if the driver supports accel for X.

Appreciate!
May I know battery life and the status of sound/video accelerator/bluetooth?
currently none of the them do in linux natively. I am working on sound currently tho

forwarding devices lsusb
Hi, how can I forward my usb devices to chrooted linux? If I plug in an external usb device I can see it via lsusb in adb shell / terminal emulator. I tried using mount -bind /my_device_directory /chroot/path/my_device_directory, however when I run lsusb in chroot nothing is returned.
Thanks

slimm609 the new extsd kernel works just fine. How do you have the wireless setup? Bringing the wlan0 interface up and do a scan returns no networks, do you have the required modules pre-inserted or do we need to insert them after boot?
Keep up the great work, I will contribute when I can.

Also you can "Dual boot" in a fashion by using flash_image and just swapping kernels.
A couple of limitations apply, you have to setup the sdcards correctly, if you have backtrack on internal then your android rom must use the external sdcard on /sdcard.
The command to flash the kernel is:
From android:
From backtrack (you must copy the flash_image binary from android or recovery):
Also you do not need to nvflash at all using this method as long as you are already on a 1.1 based bootlader.
In theory it would be possible to create a recovery installable .zip that would handle every part of the install of backtrack.

updated links and some instructions.
I currently do not have time to do any work on this currently as i have been working 18+ hours a day. Hopefully if i ever get some time again I will continue it.
Jaybob413 built the kernel for 1.2 Bootloader. Link is posted below
Thanks jaybob413

THIS MAY ERASE EVERYTHING ON YOUR TABLET!!!!
Do this at your own risk!! I take no responsibility for anything that happens to your tablet.
Start by installing your favorite ROM and kernel.
Make sure you have adb working and CWM installed
turn off the device then boot into recovery. (vol+ and power).
once in recovery you must format the EXTERNAL sdcard into ext3.
Code:adb shell parted /dev/block/mmcblk2 mkfs 1 ext2 confirm exit tune2fs -j /dev/block/mmcblk2p1 to format the external SDcard to ext3 mkdir /tmp/ext-sd mount /dev/block/mmcblk2p1 /tmp/ext-sd/
exit adb and run
* this will take a long time *
Code:on a linux box unxz bt5.tar.xz adb push c:\path\to\bt5.tar /tmp/ext-sd/bt5.tar adb shell # cd /tmp/ext-sd/ tar xvf bt5.tar rm bt5.tar cd / umount /tmp/ext-sd/
reboot the device into android and connect the INTERNAL sdcard to the computer to place files on to the sdcard.
make a directory called kernels on the sdcard and put the 3 zips from above in that folder.
bt5kern-01-20110525.zip
droid-kern_backup.zip
restore_droid-kern.zip
reboot into recovery and flash the
droid-kern_backup.zip this will create a backup of the android kernel. This will ONLY need to be done any time that you UPGRADE or CHANGE your android kernel.
once this is done you switch back and forth between android and backtrack with:
bt5kern-{date}.zip to boot into backtrack
restore_droid-kern.zip to boot into android
******* You do NOT have to wipe cache or anything when switching back and forth. Just flash whichever you want to boot into and you are done************

************OLD WAY******************
How to install backtrack 5 to run on the gtablet with out gtab filesystem modification.
You must recreate the img file to be less then 4Gb. The img file is currently 4.6Gb. The new image created will be 2.9Gb. this is a vfat limitation
this has been tested on vegan 5.1 with the gtab/zpad 1.4 OC kernel. Its still a little buggy with random reboots depending on what your are doing but it is a WIP
The kernel must have loop devices support. Also looks like the kernel needs swap functionality to be enabled.
I could release the img file that has already been created but backtrack would prefer that people not release other images so this will allow you to create your own after downloading it from them so it remains trusted.
you either need:
linux with ADB working on the gtab
OR
windows with ADB and access to a linux box with about 10gb of free space.
Backup your sdcard because it needs to be repartitioned with CWM.
In CWM under advanced > Partition SD Card > 2048 > 128
download the arm version of backtrack from www.backtrack-linux.org/downloads/
and extract the files. you need to copy the bt5.img.gz to the linux box and do all the following steps.
make a working directory for all the files, copy and gunzip the img file
Code:mkdir bt5 cp /root/bt5.img.gz bt5 cd bt5 gunzip bt5.img.gz
rename the old bt5.img to something else and create a new image that fits onto the gtabs vfat filesystem.
then create 2 directory to mount each image and copy the files over to the new img file.
Code:mv bt5.img bt5.old.img dd if=/dev/zero of=bt5.img bs=4k count=900000 mke2fs -F -i 8192 bt5.img mkdir bt5old bt5new mount -o loop bt5.old.img bt5old mount -o loop bt5.img bt5new cd bt5old cp -rp * ../bt5new
*****************************************
since the system does not go through the full startup scripts once you run "sh bootbt" you must run /etc/rc.local from the chroot to start the vnc server if you add these lines otherwise you must type them each time.
Code:cd ../bt5new/ vi etc/rc.local and add the following 2 lines before the exit 0 line export USER=root /usr/bin/startvnc
save the file and then continue on.
also you can edit /usr/bin/startvnc and modify the screensize to fit the tablet
the gtablet is 1024x600
Code:vncserver -geometry 1024x600
*****************************************
after all files have been copied over you just unmount the 2 directories and gzip the new image.
Code:cd .. (you should now be in the directory with the 2 img files and 2 directories) umount bt5old umount bt5new gzip bt5.img
edit the bootbt file and change the line
withCode:mount -o remount,rw /dev/block/mmcblk0p5 /system
*** this needs to be changed to whatever your /system is on your tablet or phone if it is something other then the gtablet.Code:mount -o remount,rw /dev/block/mtdblock3 /system
now copy this new bt5.img.gz file over to the directory where you got the original image from and then follow the instructions that are included with the download in the README file.
a good VNC viewer is located
http://code.google.com/p/android-vnc-viewer/downloads/list
and also install a terminal emulator so you can start Backtrack 5 from the device.
---BUGS---
running from a terminal emulator everything runs fine but running VNC gnome takes up way to much RAM currently. Looking at fluxbox and/or swap as a fix. causes the tablet to lock up and must be powered off by holding the power button.
---Thanks---
The Backtrack Team -- for coming up with an amazing security distro
The G-TabDevs Team -- for the vegan 5.1 Rom
Pershoot -- for maintaining the 1.4 kernel for the gtab and hopefully adding support for needed features =)
Sorry for the flash in the pictures
3BL1.2 test
I was too impatient to wait any longer for a BL1.2 version, so I rebuilt the kernel with CONFIG_NEWBL=y and updated the posted kernel zip with the new version (bt5kern-bl2.zip). Also attached are the updated LKM files (dhd.ko and scsi_wait_scan.ko) in a separate file (bt5-bl2-lkm.zip). These files will go into the rootfs on your sdcard in /lib/modules/2.6.32.42-slimm/kernel/drivers/... as described in the README included in the zip.
As always, be safe. All risk is assumed by the user.2
edit wpa_supplicant.conf in /etc/
run
"wpa_supplicant -BDwext -iwlan0 -c/etc/wpa_supplicant.conf &"
"dhclient"
that will get it working then you can install wicd from the repos. (not sure if you need network manager also??)2wifi is working now. tested with wpa-psk
New files coming tomorrow with wifi included.
the touchscreen is seen by the system and xorg just need to find the right configuration for it to work
now trying to compile as a single touch device because Xorg does not support multi-touch displays
