Re: Introducing ubiboot N9 (multiboot OS loader)
 

Okay, now a new version of ubiboot-02 (rev. 0.3.1) is ready for download at swagman.

Props for coderus with helping to debug the race condition I had in the previous version :)

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Well, I thought more about using sequence from 01 (mtd4/5 r/w). And new logic from 02.
As I see the init code is compiled into the kernel, so there is no chance for own debugging any more, right?


And out of curiosity: what was the problem with harmattans autoboot? I took a look, but did not see nay suspicious.

Re: Introducing ubiboot N9 (multiboot OS loader)
 

What about the ubiboot-01 you find that you need, is it the softlinks in /boot/, like do you need Nemo->/mnt/8 or something like that?
The links are in the cpio, so it's only necessary to change that.

The root cause was not the G_HARMATTAN_AUTOBOOT=1 setting, and neither it was the VFAT on /mtd/4. Actually it was a race condition in init that caused /mtd/2 to be umounted before the kernel selection :eek:
For the whole story, see the IRC log at http://www.swagman.org/juice/ubiboot/irclog

Re: Introducing ubiboot N9 (multiboot OS loader)
 

no that dosn't matter. Will try the 0.3.1 next.

Re: Introducing ubiboot N9 (multiboot OS loader)
 

I think that won't fit. My mtd5 is ~25MB the cpio file >50MB. Have to use it on ~/MyDocs/boot.

The mtd5 is a nice fallback, if you have to debug a little more ;-)

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Please do, that one fixes the selection bug.

What's your HW revision btw? I am still collecting data about revisions where ubiboot has problems, to find out if rev.1603 is the only problematic device.

1501

The 0.3.1 did the first successfull boot. I only changed the cpio-file and flashed the new kernel.

Thanks.

Re: Introducing ubiboot N9 (multiboot OS loader)
 

You can actually trim down thd cpio quite a lot. Most of the 50M is extra kernel modules which I included just in case (for future expansion needs).

You can delete the /lib/modules hierarchy from the cpio and repack it, and the size will be about 3.6M :D

Re: Introducing ubiboot N9 (multiboot OS loader)
 

@juiceme
Could you please post the command for cpio, as I am not used to that format and do not know which parameters to give for packing (unpacking is easy :)).


I had a deeper look into sources this evening, and I was a bit "disappointed" (dont get me wrong!). I thought with G_MOUNTABLE_PARTITIONS we also got configurable Nemo partition. But that is not the case. So I made my own configuration. Not yet tested, as I am on the road without flasher tools, so if you could check that and use that maybe?
I think it will work and all changes are based on 05042013 version. So a diff will let you know easily.
Of course I do need it only for Nemo. But maybe later I want to move Nit to another real partition. And for Harmattan this maybe could also be usable to have a safe copy (dd p2 to p5) of a bootable Harmattan version for developers/tweakers?

--edit
I forgot about the links /boot/Nemo and /boot/Harmattan to /mnt/x.
Attached is v2 of my mods (only affected:@select_animated_os.sh).
They are checked to point to correct configured partition number, else they are removed and created again. I do not know if this is possible with cpio version?

--edit
corrected nit partition number in conf
set chroot folder for nit back to 0p3/nitdroid (default)
added hack for aegis store (.aegisfs, .account, .activesync), onyl needed (or maybe not at all, discussion ongoing) for switching between stock and openmode kernel (hereby creating accounts)

Re: Introducing ubiboot N9 (multiboot OS loader)
 

To unpack the cpio archive to current directory with command: "cpio -id --no-absolute-filenames < ubiboot-02.menus.cpio"

Tp repack the current directory to cpio archive, use command "find . | cpio -H newc -o > ../ubiboot-02.menus.cpio"


Yes, you are of course correct :)
At some point I thought about that, just like I have the initscript defined like in G_HARMATTAN_INITSCRIPT I should perhaps have the partition also configurable...
I just did not implement it at that time :D

Maybe the partition should also be defined like a sed replacement string for the whole partition name
(something like G_HARMATTAN_PARTITION="\/dev\/mmcblk0p2")
