Oct 24 08:53:39 <abhishek___> Please suggest me

Oct 24 09:00:51 <abhishek___> Please suggest me
Oct 24 09:36:26 <abhishek___> I have development board with Android preloaded on it. I want to run the Ubuntu desktop version on it. What steps I need to perform?
Oct 24 09:36:33 <abhishek___> Please suggest me
Oct 24 09:48:32 <shadeslayer> abhishek___: what board?
Oct 24 09:48:47 <abhishek___> IFC6410
Oct 24 09:49:14 <abhishek___> shadeslayer: I have IFC6410 board with Android pre-loaded on  it
Oct 24 09:49:51 <abhishek___> shadeslayer: I have source code of Android ......downloaded from codeaurora
Oct 24 09:50:09 <abhishek___> shadeslayer:  I want to run Ubuntu desktop on it?
Oct 24 09:50:28 <abhishek___> shadeslayer: can you please suggest me what steps to follow?
Oct 24 09:52:39 <shadeslayer> abhishek___: start with compiling the kernel that comes with it, pack a ubuntu ARM initramfs, combine the two together to create a flashable image, create a standard ubuntu image ( just the ubuntu-standard package) and then flash all of that and try to boot it?
Oct 24 09:54:20 <abhishek___> shadeslayer: I have compiled the kernel .....(Also, I can pic the zImage from Android images available to me)
Oct 24 09:54:33 <shadeslayer> not quite
Oct 24 09:54:48 <shadeslayer> you'll probably have to enable various other kernel options
Oct 24 09:54:49 <abhishek___> shadeslayer: from where to get the Ubuntu ARM initramfs ?
Oct 24 09:55:16 <shadeslayer> abhishek___: you'll have to make one, I usually run mkinitramfs in a ubuntu arm chroot
Oct 24 09:55:27 <abhishek___> shadeslayer: Ok ....I will compile the kernel all by myself and will create the zImage
Oct 24 09:56:52 <abhishek___> shadeslayer: can you please explain
Oct 24 09:57:19 <shadeslayer> explain what
Oct 24 09:57:50 <ogra_> shadeslayer, update-initramfs ... never use mkinitramfs directly
Oct 24 09:57:52 <abhishek___>  I usually run mkinitramfs in a ubuntu arm chroot
Oct 24 09:58:09 <shadeslayer> ogra_: oh, does mkinitramfs eat kittens?
Oct 24 09:58:16 <ogra_> it misses a lot
Oct 24 09:58:23 <shadeslayer> ah I see
Oct 24 09:58:37 <ogra_> its only one step in building an ubuntu initrd (update-initramfs calls it in the end)
Oct 24 09:58:46 <shadeslayer> abhishek___: just debootstrap a ubuntu arm chroot
Oct 24 09:58:52 <shadeslayer> and then chroot into it
Oct 24 09:58:59 <shadeslayer> call update-initramfs
Oct 24 09:59:01 <ogra_> or crab an ubuntu-core tarball
Oct 24 09:59:03 <ogra_> *grab
Oct 24 09:59:07 <shadeslayer> or that ^
Oct 24 09:59:25 <shadeslayer> ( must be something new, I haven't followed ARM stuff in the last 6 months :)
Oct 24 09:59:45 <ogra_> what is new ? ubuntu-core ?
Oct 24 09:59:52 <ogra_> its 3 years old or so
Oct 24 09:59:52 <abhishek___> Ubuntu core tarball can be picked from https://wiki.ubuntu.com/Core
Oct 24 10:00:03 <shadeslayer> oh okay, first time I'm hearing of it :S
Oct 24 10:00:29 <ogra_> well, you need to fiddle with qemu-user/static if you want to chroot into it
Oct 24 10:00:37 <abhishek___> ogra_ : from where to pic the tarball
Oct 24 10:00:51 <ogra_> so qemu-debootstrap is probably the better choice since that does everything for you
Oct 24 10:01:39 <ogra_> abhishek___, there should be links on the wikipage
Oct 24 10:02:04 <abhishek___> ogra_ : can you please link the traces
Oct 24 10:02:13 <ogra_> ?
Oct 24 10:02:21 <abhishek___> ogra_ : I have kernel image ...compiled for my board
Oct 24 10:02:29 <shadeslayer> http://cdimage.ubuntu.com/ubuntu-core/releases/13.10/release/ ?
Oct 24 10:02:39 <abhishek___> now from where to get the initramfs
Oct 24 10:02:40 <ogra_> you will likely need to rebuild it woith many android options dropped
Oct 24 10:02:46 <shadeslayer> ^^
Oct 24 10:03:22 <ogra_> you need to create a chroot or use a core tarball, chroot into it (with /sys, /dev and /proc bindmounted ... and then call update-initramfs
Oct 24 10:03:37 <abhishek___> Ok.....I have kernel image compiled for my board
Oct 24 10:03:56 <shadeslayer> no you don't
Oct 24 10:04:01 <shadeslayer> <ogra_> you will likely need to rebuild it woith many android options dropped
Oct 24 10:04:04 <ogra_> yes, recompile it with android dropped
Oct 24 10:04:26 <abhishek___> ok ....I will recompile with android dropped
Oct 24 10:04:37 * shadeslayer has to go, cya
Oct 24 10:05:19 <abhishek___> ogra_: I also require the bootloader ?
Oct 24 10:05:35 <ogra_> indeed, that is what loads your kernel and initrd
Oct 24 10:06:06 <abhishek___> ogra_ : Android images uses fastboot\
Oct 24 10:06:21 <ogra_> thats fine
Oct 24 10:06:24 <abhishek___> ogra_ : can I use that to load the Ubuntu
Oct 24 10:06:45 <ogra_> yes, you need to use abootimg to create a boot.img file from your kernel and initrd
Oct 24 10:07:00 <ogra_> that one you can feed to fastboot
Oct 24 10:08:04 <abhishek___> ogra_ : So, I have kernel image (fresly compiled for my board) and Ubuntu core tarball .....I will pack those to create boot.img image
Oct 24 10:08:14 <ogra_> no
Oct 24 10:08:19 <ogra_> you need to create an initrd first
Oct 24 10:08:34 <abhishek___> ogra_ : How to create initrd ?
Oct 24 10:08:35 <ogra_> a) compile the kernel with a config that works under ubuntu
Oct 24 10:08:45 <ogra_> b) create an initrd.img
Oct 24 10:08:48 <abhishek___> ok
Oct 24 10:08:54 <ogra_> c) create a boot.img using abootimg
Oct 24 10:09:09 <abhishek___> how to create initrd.img
Oct 24 10:09:11 <ogra_> d) flash the boot.img to the right place so fastboot will find it
Oct 24 10:09:32 <ogra_> e) put the ubuntu-core tarball in place so the initrd can find it and boot into it
Oct 24 10:10:03 <ogra_> abhishek___, that was explained to you a few times now
Oct 24 10:10:12 <ogra_> (how to create an initrd)
Oct 24 10:10:26 <ogra_> for more details please look at documentation of the different tools
Oct 24 10:11:38 <abhishek___> initrd.img using update-initramfs ???
Oct 24 10:12:41 <abhishek___> If I flash the boot.img in the boot sector (using: fastboot flash boot boot.img) .....
Oct 24 10:12:48 <hrw> ogra_: ubuntu used cavium model for arm64 work?
Oct 24 10:13:30 <ogra_> hrw, no idea
Oct 24 10:13:41 <ogra_> hrw, ask infinity
Oct 24 10:13:44 <abhishek___> ogra_ : I also require the recovery.img, system.img images ...
Oct 24 10:13:49 <hrw> ogra_: mkey, thanks
Oct 24 10:15:07 <abhishek___> ogra_ : will I am able to boot the board into ubuntu desktop using the steps explained by you? ....I think I also require the recovery.img and system.img image .....is it not required?
Oct 24 10:16:27 <abhishek___> ogra_ : you gave me step "e) put the ubuntu-core tarball in place so the initrd can find it and boot into it"
Oct 24 10:17:48 <abhishek___> ogra_ : Please tell me .....I am new to this activity ?
Oct 24 10:23:21 <ogra_> abhishek___, why do you care for e) before even having done a) ?
Oct 24 10:23:33 <ogra_> (which might take you days anyway)
Oct 24 10:24:47 <ogra_> expect that you need to read a lot of documentation and dont expect to be dont within a week or two if you havent done this before ... this is not a beginner task and will require you a lot of time and learning
Oct 24 10:25:14 <abhishek___> ogra_ : I have read on the web that if Android boot.img is wrong ...then it will boot from the recovery image .......
Oct 24 10:25:55 <ogra_> yes, thats what the bootloader might do ... depends on how the vendor created it
Oct 24 10:26:17 <ogra_> but recovery or system or all the other android stuff is unrelated
Oct 24 10:26:35 <abhishek___> ogra_ : so, if i flash the ubuntu boot.img in the boot sector and boot the board ...then Android will boot from the recovery image ....and then again i will be in Android
Oct 24 10:26:56 <ogra_> so make sure to have a working boot.img
Oct 24 10:27:13 <ogra_> try to find out whats wrong using the right android debugging tools and fix that
Oct 24 10:27:22 <abhishek___> ogra_ : My problem is ...I don't have uboot (standard bootloader) ...
Oct 24 10:27:38 <ogra_> you dont need uboot
Oct 24 10:27:47 <ogra_> just create a proper boot.img
Oct 24 10:27:48 <abhishek___> ogra_ : So, I don't require bootloader (u-boot)
Oct 24 10:27:59 <ogra_> you have a bootloader already
Oct 24 10:28:17 <abhishek___> If I am able to create the correct boot.img ....then I am able to boot the uBuntu on it ?
Oct 24 10:28:44 <abhishek___> ok .....what abt the GUI ?
Oct 24 10:29:30 <ogra_> stop juping that far ahead, lets talk in one or two weeks about GUIs ... get it booting first
Oct 24 10:29:36 <abhishek___> ogra_ :  can you please give me your email-id ?? .......I will try to follow the steps as mentioned by you .....and will ask you for further suggestions .....
Oct 24 10:29:47 <abhishek___> ok ......
Oct 24 10:30:12 <ogra_> if you have questions it is better to use th eubuntu-devel mailing list, i'll answer there
Oct 24 10:30:48 <abhishek___> ok ...
Oct 24 10:31:57 <abhishek___> ogra_ :  thanks for your help .....
