Re: Introducing ubiboot N9 (multiboot OS loader)
 

It is working fine with the prenits that you have provided so I am going to run with it for now. My main aim of getting ubiboot was to install nemo so I can decide on my next phone. I am thinking b/w sailfish and canonical right now. Hope this helps me decide. :cool:

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Well yes you are right maybe that should be removed once and for all... Having that option in preinit messes up the VOIP and in Harmattan you cannot really access the device via SSH until fairly late stage of boot, it's better to get to the device via seral adapter and R&D mode*if that is required.

First thing that comes up my mind is tagging the place in the preinit with some nice symbol, something like G_IP_ADDRESS_TO_BE_ASSIGNED and then in ubiboot domain to run sed on the file and replace that with the desired address.
That would work just once, though as of course on the second run it had already been changed.
Having a bit more complex sed script, you could well have a marker there to signify the place of replacement so that is leaves the marker section there for subsequent runs.
Possible, but is it useful for many people?

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Yep, please remove that then.
And thanks for confirmation (of my bs talk :))! I had smth like that in mind, but ...


Nope, probably not.
But again thanks for pointing to me a possible way to do it (in init of ubiboot). If I am going to do so, I will send you sources. But I do not think so, as it will be only me using p5 for nitdroid nd wanting an own unique IP address. So direct edit will be okay.

But configuration for IP and DHCP range would be nice in ubiboot.


--info
today I got nitdroid booted from p5 :) (call me dumb *ss, as it was again a wrong link :mad:
but some error popped up about android worker process stopped
now I need to fix that :( but maybe it is just due to some SIM card registration failure I have since today?!?
Yes! It is working.

Next step will be booting harmattan with rootfs from p5.
Any idea how to block access to p2, so we can be sure that everything is loaded from p5?

Documentation for ubiboot-02 Installation
 

Hi Friends,

It's been quite a while since I have posted...this "ubiboot-02" is great!

I gave it a try and so far so good; was able to boot up with Harmattan/NITDroid/Nemo. However, I got a little confused with the steps documented in the README file. I participate in a local forum site here in the Philippines where there are also enthusiasts of the Nokia N900 and Nokia N9/50. They are also interested in ubiboot-02, but they did share the same sentiment (that they got confused with the README).

So what I did is to document the steps that I took to get this to work. Initially I intended to have this for personal use, but then again, I thought it might benefit others. Hence, I hope you won't mind if I share this here too. I already converted it to PDF, but I also have the original document.

There are file size restrictions so I wasn't able to attach the documents directly using the Attachment Tool. I uploaded it via Mediafire instead: http://www.mediafire.com/folder/4zua...6cy/ubiboot-02

I have also recorded a video of the steps. I am just converting the videos and will upload (will edit this post accordingly).

Hi Friends,

I attempted to make my first Wiki Page. :) I used the Ubiboot Steps to make it. Please review and hope you like it. Feedback is most welcome (preferably via PM as I am not always online on the forums).

http://wiki.maemo.org/Ubiboot

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Thanks, on first reading the guide seems to be pretty complete :)
I also attempted my first wiki page edit, and I added skeiron as the mirror location of ubiboot files.

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Hej juiceme,

I think I spotted some hurdle when trying to boot harmattan from p5.

Taking a deeper look into the files compiled into the kernel, I have seen that you symlink /etc/passwd and /etc/group directly hardcoded from /mnt/2/etc/ passwd respective /mnt/2/etc/group.
This is what I wanted to avoid (to have the need for some harmattan files/dirs accessible on p2).

I edited /init (attached), but I am absolutely not sure if this will work.
When, at what time, the ubi system needs passwd and group?
If it is only when launching a shell, I think my small modification (peterleinchen 1) may work. But when it is already needed for starting /init itself, then I am doomed. In first case what about the maintenance mode: do we need it here also as it starts a shell (I have begun to modify: peterleinchen 2)?
Please take a look and let me know, please.


And i thought about changing the log location to /mnt/p1/boot/log (peterleinchen 3) as this location is visible to all operating systems and easily to access for everybody. I thought also about saving log to the selected OS /var/log location, but after rethinking discarded this idea. What do you think? (of course this needs to be fixed in all files then as well)

And I edited the wiki for the open mode preparation as Jonni told us. I did not do it this way, but it cannot harm nor cause trouble to try out (if you wanna flash)!

-- oops
forgot the attachment, corrected.

Re: Introducing ubiboot N9 (multiboot OS loader)
 

@juiceme: thanks for reviewing and for adding the mirror site.

@peterleinchen: thanks for adding the tip. :) Actually, I am aware that when the device is newly flashed, the "prepare for Open-Mode" steps will not be required because the folders ./accounts, ./aegis, and ./activesync are still at an empty state, but I just had to put it in there for "mistake-proofing" of "fool-proofing" (I conscientiously thought that there will be a lot of end-users who will try out Ubiboot), just to be sure.

By the way, I cleaned up your edit a bit for formatting consistency, hope you won't mind. :)

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Hi!

I reviewed your changes, and there are some things to note.

First thing, though, you have an older version of init, where you are placing your modifications. Your version does not contain the corrected watchdog kicker and it has the incorrect BME initialization which cause the rev.1603 boot problems with Harmattan. Also the boot partition configuration changes are missing.

Here is the current version of init from the latest ubiboot-02: Attachment 32482

Then, comments about the edits:

1. Actually the symlinks to /etc/passwd and /etc/group are not used for anything at all at the moment. The files are there just as I am trying to get SSHD to work. SSHD requires the entries to manage userids, and my idea here was to symlink those from the Harmattan side so that I could reuse the Harmattan credentials on ubiboot domain. This is maybe a futile idea anyway, so the files are totally excess as of current. (meaning, just do not care if the links point to nothing at all...)

2. About choosing the logging location. Yes, you are absolutely correct there are far better places than Harmattan's /var/log/ to store the logs, obvious location would be of course where ubiboot.conf and the cpio are. Or it could be made configurable in the conf file.
I do not remember exactly what I was thinking when decided to put the logs there... maybe it went on something like, if there's a problem with something users tend do look into /var/log/ to see if there's a hint of the cause...

Re: Introducing ubiboot N9 (multiboot OS loader)
 

There is a similar situation when remote-unlocking an encrypted hard drive. In that scenario, passwd is empty and the auth is key-based. This may be feasible in this case.
