maemo.org - Talk - [Android] NITDroid V2 Development Topic

I think we're still waiting for either wifi or cellular to work in nitdroid before we see detailed instructions ;)

right now there is no wifi and no cell, and no dual boot. so it isn't very useful and you would have to go through the process of un-installing nitdroid to get back to maemo.

Really? I thought the whole point of installing it onto a memory card, is that then you dont have to un-install it, you can just remove the memory card. So is this not true?
Oh, wait the instructions on the first page are for N8x0.. So does this not work on the N900 at all?! I swear i saw a video somewhere with the N900 running android..

Re: [Android] NITDroid V2 Development Topic

page 30 your looking for :) but at min it requires flashing a different kernel to boot android due to the way androids systems link to special kernel modules. i have not made a multi boot kernel that works as yet so flashing back and forth is needed but as said not a lot in android works as yet as it is still early development stages (and i am working mostly alone and in my spare time)

Re: [Android] NITDroid V2 Development Topic

I am looking forward to testing on my n810. Let me know if I can do anything helpful on that front.

As a side note, I appreciate everything you are doing, and cannot express how happy I am to hear that someone is pushing the nx0 to future validity again. I almost lost hope! You can count on a paypal donation from me, and I also need to dig through my old am2 systems and see If I have some spare parts for your compiling rig. I might have some ddr2 and maybe a proc (although I think it's a 1.6 single core)

Thank you very, very much.

the kernel i have provided here is hard coded to boot direct from device b202 (aka the external microsd) it will not boot maemo in any way at this time

this kernel is patched with titans patchs and is overclock enabled if anyone feels adventourous enough to copy the required filess of their maemo partition to the microsd to try this let me know

requirements
knowledge of how to flash your device

my android rootfs: http://files2.nitdroid.com/nitdroid-....0.1-demo.tbz2

my kernel image: http://files2.nitdroid.com/zimage-nitdroid-0.0.1

1 microsd card (i'd say min of 1gb, this how-to will show the layout for my 8gb)

some idea how to edit files and run commands via a terminal

linux based pc/vm

(optional but recommended) some sort of ssh server installed in maemo5

how-to:
1. Grab the required files from above.
2. Login to your n900 as root (either xterminal or over ssh (ssh is easier) ) and run the command below:

Code:

sysinfo-tool -g /certs/npc/esn/bt_id

keep a note of the value it returns as you need it further on in this howto
3. Mount your microsd via either n900s usb storage or direct via a card reader (probably faster to do latter) then find out the device node assigned to it on you linux system (dmesg will give you easily enough) then run the following (/dev/sdb is the node the microsd shows as on my system):

Code:

fdisk /dev/sdb o n p 1 <press return> +2g t c n p 2 <press enter> <press enter> w q

this should correctly partition your microsd for the next stage
4. Now create filesystems,

Code:

mkdosfs /dev/sdb1 mke2fs -j /dev/sdb2 -m0

5. Once those have ran mount the ext3 partition

Code:

mount /dev/sdb2 /mnt

6. Now navigate to that folder and extract the rootfs (i hope you saved it somewhere you can remember :) )

Code:

cd /mnt tar xjvvpf ../nitdroid-n900-0.0.1-demo.tbz2

7. Wait patiently for the extract to complete (it takes some time)
8. Once the extraction has completed navigate to the system/bin folder and open the load_modules.sh file in your favourite editor (i use nano)

Code:

cd /mnt/system/bin nano load_modules.sh

9. Scroll down the file and find the line that starts
echo 0cddef0a0e6d and replace the 0cddef0a0e6d with the text you wrote down in step 2 - this is to enable the bluetooth module to work. Once that is done save and close the file then you can unmount the microsd

Code:

umount /mnt

10. Insert the microsd into your n900 and then power down the device (disconnect charger etc before hand.)
11. Boot your n900 into 'flash' mode (hold u on keyboard as you connect usb cable)
12. Run the following command to flash the kernel to your device

Code:

flasher-3.5 --set-rd-flags=no-ext-wd,no-lifeguard-reset --enable-rd-mode -f -k zimage-nitdroid-0.0.1 -r

adjust the zimage part to give the path to where you saved the file

the device should reboot and begin to start android.

The back cover must be in place or the system will crash

How to return to booting maemo? Using

Linux is case-sensitive.

Try flasher-3.5 -f -k pr12image -r

Or check the flasher help.

Re: [Android] NITDroid V2 Development Topic

There's a way to get the device to just boot a custom kernel once off, as opposed to flashing it. Look under the recommended MeeGo instructions for the N900 and it will give the flasher command there.

Re: [Android] NITDroid V2 Development Topic

Hey

You know how you mention on the first page that you got rid of Google apps, does that include Google goggles? Cos having that would be pretty darn awesome, although me having programmed before i know that asking for something like Google goggles may be a VERY tall order! But yeah was just curious :)

Keep up the good work man! Seriously appreciated!

Yep, I know its case-sensitive and the switches F and R are allright, I was just curious, how to return to maemo.

So, just reflashing the kernel from pr1.2 gets the job done? I havent installed droid yet ...

Re: [Android] NITDroid V2 Development Topic

im my case i run the command

Code:

flasher-3.5 --disable-rd-mode -F RX-51.bin --flash-only=kernel -f -R

then once im into maemo i reflash titans kernel by reinstalling the package through apt

Yes, once you unpack the droid fs onto the sd card you just flash kernels to switch between the two.

Re: [Android] NITDroid V2 Development Topic

Dualboot kernel for Android and Maemo PR 1.2 is... almost stable.

http://newsycat.com/android/n900/zImage
http://newsycat.com/android/n900/tsc2005.ko (put to Android rootfs /system/lib/modules)

Copy all kernel modules (except tsc2005) from maemo to android rootfs.

And run as usual (see notes @ nitdroid.com).

I'll upload new stable rootfs later (tonight or tommorow morning, little busy right now).

http://newsycat.com/android/n900/n900_kernel.patch.gz (modified and cleaned up patch from nitdroid. Don't care about some rejects, it related only to BT/hci).
___

What does I meant by "almost stable"?
You need to remove back cover of n900 to boot Maemo (to disable external SD actually). Some BME troubles happens, and I eventually found this workaround.

Second problem is internal DNS resolver. It doesn't work.
just add external nameserver to /etc/resolv.conf
(i.e 8.8.8.8)

Questions/suggestions? can reach me @ #nitdroid irc channel.

Re: [Android] NITDroid V2 Development Topic

to e-yes:

1) "Copy all kernel modules (except tsc2005) from maemo to android rootfs."

You mean from N900 /lib/modules/* to microSD android /system/lib/modules/?

2) http://newsycat.com/android/n900/n900_kernel.patch.gz Where to put this one pls?

3) Am I supposed to use your zImage to flash my device instead of that zimage-something-demo from the guide?

Thanks :)

EDIT: I followed the copied all that stuff from guide to where its supposed to be ... copied the modules, used this new kernel file to flash via the command written in the guide ... and I ended up with "maemo enter pin screen" - but there were squares instead of digits ...

Hm, Ive got bootmenu installed (I was trying MER) ...and with droid, I got NO option to choose boot partition from - thats the situation after trying to use the modded kernel allowing "dualboot" - now, I just tried your guide alone and its not booting at all - only the screen with RD icon and nothing more ...

Nope, I didnt - I remove USB always right after the flasher is finished ... and nothing then, except for Nokia logo and RD logo ...

And e-yes kernel boots up into that squared stuff ... Weird.

theirs the problem, rd mode (or my kernel not sure which) wont seem to boot without usb connected try connecting it and restarting n900 (pull> reconnect batt and replace cover at same time - challenging but doable

Hello, I've tried the guide on page 30 of this thread and I cant get fdisk to work :( I ran dmesg, looked for a drive the same size as my MicroSD (16GB) is was node sdd. I ran fdisk /dev/sdd and It justa said could not find /dev/sdd ... I am booting Ubuntiu 10.04 from usb iso using a hacked u3 drive, could this be the problem? Can I set up the MicroSD using Gparted? Any help would be greatly apreciated..

Re: [Android] NITDroid V2 Development Topic

My primary target now is create stable kernel for both Android and Maemo. I'm trying to create minimalistic Android patchset for applying to kernel-omap1 or kernel-power. quilt is very useful in that task.
Current progress:
user@maemo-sdk:~/kernel.power$ quilt files
drivers/misc/Kconfig
drivers/misc/Makefile
drivers/misc/pmem.c
drivers/rtc/Kconfig
drivers/rtc/Makefile
drivers/rtc/alarm.c
drivers/staging/Kconfig
drivers/staging/Makefile
drivers/staging/android/Kconfig
drivers/staging/android/Makefile
drivers/staging/android/binder.c
drivers/staging/android/binder.h
drivers/staging/android/logger.c
drivers/staging/android/logger.h
drivers/staging/android/lowmemorykiller.c
drivers/staging/android/ram_console.c
drivers/staging/android/timed_gpio.c
drivers/staging/android/timed_gpio.h
drivers/staging/android/timed_output.c
drivers/staging/android/timed_output.h
include/linux/android_aid.h
include/linux/android_alarm.h
include/linux/android_pmem.h
include/linux/ashmem.h
init/Kconfig
mm/Makefile
mm/ashmem.c

I plan to test new kernel patch and upload it and rootfs (which I promised upload today. sorry:)) as it will be done.

wifi, sound etc. has to be solved. once primary target will be achieved.

It depends on the size of your card. Probably best is to make first partition windows and the second linux with at least 1gb free ... in case of my 4gb microsdhc, I divedi it into halfs :)
