maemo.org - Talk - [WIP] Ubuntu 9.10 on the N900

I'm not 100% where it is located on your N900 (bootmenu).

I have a zimage (which will work for as well) in:
/boot/ and in /boot/multiboot (you may have a /boot/bootmenu/ )

and I have them in:
/etc/multiboot/

So maybe I'm outta luck, I'm not sure where it is - Thank you very much anyhow! :)

Re: [WIP] Ubuntu 9.10 on the N900

you should be able to just put ITEM_KERNEL="2.6.28.10power40" in your *.item and it will flash power40 when you boot.

Re: [WIP] Ubuntu 9.10 on the N900

I wanna give 10.10 a go.
When i try to get the ubuntu img on my sd it stays blank ???
I tested
sudo sh -c './ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img >/dev/sdc4

sudo dd bs=4M if=ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img of=/dev/sdc4

latest gave me output like this :

2094403584 Bytes (2,1 GB) copyed, 389,831 s, 5,4 MB/s

still empty... Where do i go wrong ? I have tested unmout whole sdc and only sdc4 nothing helped :(

Good luck. I haven't seen him post here in a while, but, Im pretty sure that h-e-n depends on bme, which is closed source. So basically without proper battery management h-e-n is out of the question.

I got the image, and try to put it on the sd, all done on a ubuntu pc, no luck yet. Dont know if this works on a partition, or if i need a whole sd ...
Gettting the files from the meego img was quite easy ...

Edit : Solved the problem by using a new sd card :D

Re: [WIP] Ubuntu 9.10 on the N900

wait it is a whole sd image not only a partition.
so it's
> /dev/mmcblck1
without the pxx
look at the ubuntu page for a copy and paste command.
and you use /dev/sdc is on purpose?

I spent all day yesterday trying to back-port drivers to 9.10, but no luck, It depends on the new kernel to much.

Could someone clear this up for me, the wikis say the A8 is armv7, but because of our broken THUMB support we can only run armv6?

Also considering the Ubuntu 10.10 image is armv7 optimized, should we build our own kernel image without thumb (if possible)?
We probably should build a root filesystem image ether way because we can make the image alot smaller by leaving out alot of the pointless/self-reinstall-able packages.

OR your way of mounting images on windows..

you get the offset via sfdisk -lu
the startnumber it tells you needs to be multiplied with the blocksize and this is the offset.

Code:

 losetup /dev/loop0  ${MEEGO_IMAGE}

 sfdisk -lu /dev/loop0

look up the start of the partition. it's the 1rst number in the line with part.type "linux" or 83 Hex and multiply it with the blocksize, should be 512(it tells you in the head!)

Code:

losetup -d /dev/loop0

wait: don't use that ooold image in the chroot howto but a new one! see for instance:
http://wiki.meego.com/ARM/N900/Install/MMC#Linux
now mount that with the offset of the real image you have( the image i tried had an offset of 512 ).

I cannot mount the meego image.

Code:

sfdisk -lu /dev/loop0

returns

Code:

unrecognized format - using sectors

I have re-downloaded the image to check that it is not corrupt and got the same error. How do I fix this?

yep - at least this is what sfdisk says..i don't know if you need a different image, or download the same image again or the losetup didn't work out. and maybe try -luB if you dont ge't units in blocks with the -lu - but that shouldn't be the issue in your case(it doesn't show you anything and not something using with wrong unit).

Ive heard qole say is 100 times at least.

So if we compile with

CONFIG_ARM_THUMB=n
CONFIG_ARM_THUMBEE=n

Thumb would be disabled?

yes: if you dissable thumb you cant execute thumbcode anymore(but imo you will want to).

and i don't doubt what you say. it's just that i want to know the issue. for it seems i am quite successfully working around an issue i am not aware of.

Re: [WIP] Ubuntu 9.10 on the N900

i want to make something clear. all that thing with patching ubuntu with the meego kernel was to show you can start it.

what it clearly is not, never was, and never was intentend to be: a way of getting a ubuntu you can use in any way. it is not. it does not work!
it is a way to get a start to how to tackle it.

i do not try to get it working with the meego or the maemo kernel or such approaches. what i do is patch up brandnew kernels to the brim with the newest patches i can find. and see if i can apply them. partly manually apply patches. change the kernel again and again and see if it works better. and get better results with every try but it is still not good. and if you go down and look a the a copied part of my modules you will find every module with a little description what it does. and thats only part of it. so you can look at it and see if you have the driver or not and might find a hint who the troublemaker could be - or give me a hint to better use some other drivers/patches.

additionally i take packages and compile them myself take other things from various gits and compile them define new depencdies to make it work and so it goes.

thats nothing you could simple copy and paste and just use.
thats nothing to put on a emmc for it may crash and simple destroy it for good. it may even render your device unusable.

but it can go very fast that we get it working. many things work. actually most. still that doesn't help much for the things that don't work spoil everything. and with ubuntu the spoilers hit one even more for it does many things automaticly which is nice for a enduser but very odd if you have a unstable thing and want to separate the troublemakers and find problems(eg network manager: )

no, a distribution it not just downloading software and installing it. its a lot, lot of work to make them work together.

again i wrote the steps together for the folks who repeatedly begged for instructions how to tackle it and for the ever repeating same questions. especially keyboard which never was an issue. and to get away from the non issue to see a loginscreen to the real issues. and i used the meego kernel only for it is a precompiled kernel good enough for the poc(no need to describe every step necessary to compile a kernel) but it is by no means realy working with it.
also: it makes no sense at all to take a precompiled kerneldriver for a kernel it wasn't built for: might work in some cases. generaly it doesn't. makes no sense to put such a thing online - the source of the patch does make sense and whoever want that will find it(have it for the kernel you use. it may have changed since it was submitted the first time).

i hope that was clear enough to how i think about this.
i really like the comunity thing and realy like to have things in the open. that is all what imo hacking is about: to see whats happening behind the scenes. and i don't keep my stuff to myself and share if it is possible, but until it is not made working: it doesn't work.

Re: [WIP] Ubuntu 9.10 on the N900

I'm still having trouble with bluetooth on 10.10 and 2.6.28.10-power45.

I copied everything in /lib/firmware and /lib/modules,
but the system->settings->bluetooth says I have no bluetooth hardware.
I tried:

Quote:

echo "<My bt address>" > /sys/devices/platform/hci_h4p/bdaddr
modprobe -r hci_h4p

but still nothing

Any hints?

Also, everything seems to segfault rather frequently. I can't open gnome-terminal, and it takes a few tries to get wicd to connect without X crashing.

most everything else seems to work ok.

2010-11-23 09:36

Re: [WIP] Ubuntu 9.10 on the N900

its anyways more than this driver. but 2.6.28 i'd say really is a no go. unless you realy copy half of maemo and even in this case expect problems. i mean: you can get it to work but the result will be either a maemo or somthing that is neither maemo nor ubuntu.

usable kernels start with 2.6.35(thats what ubuntu uses) together with bugfixes. 2.6.36 slowly becomes usable, still needs patches.

btw: i still need a frontend for the phone.

EDIT1: i think 2.6.33 was the first kernel that was able to boot but thats more like: "hurray we booted it".
EDIT2:2.6.37 might be tempting but i didn't see a lot of improvements so 2.6.36 with patches still seems the best to go atm.

EDIT3:segfauts and oopses are to expect unless everything is sane. and maemo kernel on ubuntu sure is not.
EDIT3: whatchout for thumb code as well....

I haven't had any trouble booting, logging in, and getting online with firefox (once everything is set up). I would describe it as mostly usable on 2.6.28-power45.

Unfortunately, the new microSD i just got in the mail today is garbage and has already failed, so i'm still installing to the emmc.

I've got bootmenu-n900 loading after uboot. Can I use uboot to dual-boot a different kernel from the emmc? Sorry for the lame question, but I don't really know where to begin with that one.

I would try karmic, but I've never been able to get around the inverted touchscreen when using kernel-power. Perhaps now that I have a BT mouse, it'd be worth giving it another shot.

Anyone know the command to run the bluetooth settings from the terminal on karmic?

Re: [WIP] Ubuntu 9.10 on the N900

a) uboot: yes. works fine. just point it to the kernel and the rootpartition and it boots.

b) your problem with bluetooth has little to do with ubuntu but something to do with maemo and how to set up bluetooth under maemo. as you are not using ubuntu but maemo you should be able to use the maemo stack for bluetooth and have no problem at all.
c) login: did you realize that it is a unfinished ubuntu setup or did you finalize the ubuntu setup? how did you get your useraccount? i guess you did a chroot and never came across the real problems...
d) networkmanager: is it working? powermanagment applet(any from ubuntu): does it work? or do you have the bme in the background? how does ubuntu interact with bme? could you successfully make a call with ubuntu?

EDIT: to that networmanager: ubuntu needs something to enable the phone. so what do you use? ubuntu's phonstack is telepathy-ring with ofono and on top maybe empathy. try it and look into you logs. and you'll see!

naturally. After setting up the user account in the chroot, I remove linux-image* (to avoid problems with updates), and then install openssh-server and wicd.

No, but wicd works.

haven't checked.

Quote:

I'm really not too worried about phone stuff at the moment. Presumably, if i can get my BT headset working, i could just use ekiga and sip over wifi. This would be find for me.

Really, my main reason for wanting to do this is to get a normal window manager and full keyboard support. I know i could just use easy debian for a window manager, but ctrl and alt don't work even with the bt-hid scripts. And my bluetooth keyboard performs even worse inside easydebian.

Thanks for your help. I'm not really bothered if the OS i use is some sort of Frankenstein hybrid between ubuntu and maemo, as long as it meets my needs.

yeah. the real fun starts if you realy do the first boot. it initializes the system askes you for login, for your locals(keyboard), the timezone...
and somwhere in the process... it crashes(while you are going through the wizard, networkmager probes the devices and ... ). thats what i ment with you missed a lot of fun.

you could simply chroot from maemo. some "easy ubuntu" (like the easy debian only with ubuntu ) in that case you have everything set up from maemo and the desktop from ubuntu(not completly stable but not too bad a solution if it is for the apps or the windowmanager and omitting a lot trouble ).

Why doesn't it do this when running the maemo kernel? I would have figured gdm would just launch that if there were no user accounts or something. This is a kernel thing? I suppose it's more complicated than i'd thought.

For me, the problem with this is the poor BT keyboard support inside maemo (no ctrl, alt, fn, or key repeat). I was hoping it would be better in ubuntu.

sory can't help you with that, my tries with bluetoth go as far as to pair with another machine. don't know anything about the keyboard issue. but as an idea: did you try to fuss with the xconfiguration of maemo? i can imagine that it just uses the keyboard definition it was told to use with the n900 keyboard and you need a second section for the other keyboard with a different kb type? but i don't know what i am talking about in this regard so thats only an idea ..,

Inside ubuntu, after actually entering the right command, (i'd goofed up on previous attempts, leaving out the first "modprobe;")I was able to pair the keyboard, but it didn't seem to actually do anything. I guess i'll be messing with the ubuntu xorg.conf this weekend.

My usb bluetooth adapter for my laptop should be arriving tomorrow, perhaps that will help me gain some insight on to how to handle this in ubuntu.
