Re: Introducing ubiboot N9 (multiboot OS loader)
 
Just found many people got a problem after install apps from store or deb, all running apps closed after installation, but this is not everytimes.

Maybe this is because of the hw rev problem also? same as ubiboot booting previously?

System has this process called Out of Memory handler which issues "kill -9" to the applications that are not whitelisted when memory tresshold limit is reached. And installing applications eats usually quite much memory, which causes OOM process to start the killing spree.

If the treshold limit is not reached then nothing is killed.

Ubiboot rebooting issue was more because of watchdogs not beeing triggered.

Thats nothing to do with open mode, it happens on secure mode too. System kills background applications if it decides that its low on RAM. Its a feature and not a bug.

But this happens only in open mode for me... It closes even one app, usually i don't keep much apps open...

See, ubiboot 0.3.3 searches for the conf files in this order:
1.) mtd4/
2.) mtd5/
3.) mmcblk0p1/boot/

So if you take into use your mtd4, for example, and put your ubiboot.conf and cpio there, it will find that first and not try to search for files on mmcblk0p1/boot/

I already noted before, that loading from mtd5 does not work yet (at least for me), due to not 'unmounting' mtd4 or numbering ubi devive mtd5 as #2.

Yes, and that is already fixed in the 0.3.3-alpha. The problem was a typo in initscript:

juice@osiris:~/kernel_dev$ diff 2.6.32.54-ubiboot-02_may/usr/ubifs/init 2.6.32.54-ubiboot-02_sep/usr/ubifs/init | grep /mnt/u5
< mount -t /mnt/u5
> mount /mnt/u5

Hey guys, I have a question! Some days ago I installed Ubiboot without installing Nemo (only Harmattan and NitDroid) but now I'd like to try it, what's the way to follow? Can I just follow the nemo-related steps in the wiki or I have to flash ubiboot again? :confused: Thanks :)

TMavica 2013-09-24 10:42

@juiceme i will test later when i free

No need to reflash it, just boot with the MOSLO kernel&rootfs to repartition your mmcblk0. (remember you need to have enough free space on partition 1 for this tu succeed... and of course take backup of everything...)

When the partitioning is done and you boot the device, your ubiboot environment works just like before.

When you have repartitioned the device, you can extract the Nemo rootFS to your mmcblk0p4 either via the MOSLO export or ubiboot maintanance console. (or you can do it in the device console, whatever...)

Thank you, and let me know if/when it works.
As I do not have windows I have not tested creating extfat partion and mounting it myself. (altough I guess it would not be too difficult to just port mkfs.exfat to the device)
