Re: Introducing ubiboot N9 (multiboot OS loader)
 

Well, it seems that you managed to get it working at least once, as this attempt you got into the device just fine:

root@garp-Lenovo-B590:/home/garp# ssh -i my_n9_identity root@192.168.2.15

Only, there's no command "apt-get" in ubiboot maintanance console as it is not a debian distribution, so naturally the command fails :D

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Thanks! Could you give me a command it makes sense to test!

Re: Introducing ubiboot N9 (multiboot OS loader)
 

well, "mount" for example... or "ls -l /"

Re: Introducing ubiboot N9 (multiboot OS loader)
 

@juiceme Thanks, it works!

Another Q due to this http://talk.maemo.org/showpost.php?p...postcount=1076

Does it mean installing new Sailfish version (ex. r4) in 7 partitions N9 don't need to delete all in Sailfish partition, make tar --numeric-owner -xf etc with new tar.bz2 file (and change config.conf) and start all over again in Sailfish, but only copy new version of bzImage file into Sailfish /boot/ and new version of modules folder to lib/modules in Sailfish partition and change ubiboot.conf?

Re: Introducing ubiboot N9 (multiboot OS loader)
 

That's a different thing :D

In the post you are quoting, @max83 asked about using a self-compiled new kernel with an existing Sailfish installation.
Answer to that is, yes, just put modules and kernel to ALT_OS partition (normally the mmcblk0p4 partition) and make a new kernel menu line to "Sailfish" section in ubiboot.conf.

What you are talking about here, I suppose, is having 2 different Sailfish versions on the device at the same time, on different partitions?
And the answer to that, too is "of course it is possible" :)
If you want to do that, you need of course partitions for both your installations, and the preparation is similar as for ALT_OS, untarring the images to partitions and then making ubiboot configuration entries for the partitions.
(Additionally, you could change the menu graphics (boot icons) so that you'd have for example "sailfish r3" and "sailfish r4" in your top menu...)

Re: Introducing ubiboot N9 (multiboot OS loader)
 

No then I didn't made it clear. I only have and want to have ONE Sailfish partition together with one Nemo, Harmattan, Nitdroid, Firefox. I only talk about when install new version ex. Sailfish r4 instead of Sailfish r3!

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Well, then you only need to replace the current SailfishOS r3 with r4, right?
Here's one way of doing it, altough there are many possibilities:

• get the filesystem image, for example vgrade-sailfish_r4.tar.bz2
• unpack the archive with bunzip2 to get the tar archive vgrade-sailfish_r4.tar (or if using windows use 7-zip or whatever similar tool?)
• copy the tarfile image somewhere on your N9, for example to your MyDocs/
• go to Harmattan console, and go to root with "devel-su"
• mount your ALT_OS partition with command "mount /dev/mmcblk0p4 /mnt" (now I am assuming your ALT_OS is partition 4...)
• check that you have the correct partition mounted: "ls -l /mnt" (you should see the SailfishOS partition, I assume you know what it looks like)
• delete all files from there with command "rm -rf /mnt"
• check again with command "ls -l /mnt", it should be empty now
• untar the new r4 files there with command "tar -xvf /home/user/MyDocs/vgrade-sailfish_r4.tar --numeric-owner -C /mnt"
• check that all is in order there with "ls -l /mnt"
• sync and umount; "sync ; umount /mnt"

Re: Introducing ubiboot N9 (multiboot OS loader)
 

OK yes, thanks that's the way I do it now and then will do in future!:)

Hi,

I'm following the excellent guides at http://wiki.maemo.org/Ubiboot and http://wiki.maemo.org/Sailfish but I've run into an issue with the Ubiboot-02 flash step:

The only error indicators I see are:
"ERROR: SU_GET_UPDATE_STATUS_REQ terminated with error code 1: Unknown error"
and:
Image too big to fit partition: image 219776+11952768 bytes

Has anyone else run into this or know what the problem could be? Googling the SU_GET_UPDATE_STATUS_REQ error code leads me to a few reported N900 bugs where discussions seem to point to corrupted FAT. I did the first flash step with "sudo flasher -F <yourmainfirmware.bin> -f", so I didn't flash the eMMC, nor did I do the "Zeroize Method". Would any of those methods help?

Some other deviations I did from the guide:
- I couldn't download the Firefox OS files, but I believe there's still a preint file for it
- I didn't push zImage.pr13 since it says it's not recommended
- I didn't unpack Nemo directly after flashing MOSLO - there was a reboot in between (i.e. I re-ran the MOSLO flash and then unpacked Nemo into Alt_OS).

Re: Introducing ubiboot N9 (multiboot OS loader)
 

The ubiboot image is very large; about 12M in compressed form, true, that is because it includes the root filesystem of the repair mode in the kernel image.
However I have not ever seen that it would be too big to be flashed to the kernel MTD partition.

Would it be possible that your kernel partition is smaller than on other devices? I believe that even on MTD there is some flash filesystem that removes damaged flash blocks from use, maybe your kernel partition has been reduced in size?
