Release Ubuntu 12.04 LTS on SD card

[scorpio16v]

I've a maybe stupid question.


I've logged in as user 'pandora' with password 'p'.


Now, I try to set up my network printer. The printer is recognized and to finnish the setup, it asks for the username and passwort.


But it fails at user pandora and password p. What's wrong ?

If it asks for a username it's not a regular sudo-prompt where you just have to supply your regular user password 'p'.


Is it possible that the printer or the print server needs some kind of authentication?

Can someone write a short review ? Just to know if Ubuntu is a good system on Pandora, worth installing and all ?


That would be helpful.

Since I've updated to SuperZaxxon Final, the image didn't start anymore.


Ends with "ERROR: can't get kernel image !"


Change in new OS is

Kernel 3.2 moved from /lib/boot to /boot/uImage-3 (or /boot/uImage symlinked)

So, I believe, that's the reason, right ?

 

[Linux-SWAT]

Sounds right.

 

[scorpio16v]

Hm, should I ask my questions in a more specific way to get a more complete answer ?


My wild noob guess is, that I must edit the boot.txt.


Would you, or someone other, be so kind to post a solution for unexperienced (Windows) user like me ?

 

[Linux-SWAT]

Create a /lib/boot folder on the SD_card.


Boot latest Zaxxon on NAND.


Copy /boot/uImage-3 to /media/SD_card/boot/uImage


Copy /lib/modules/3.2.21/ to /media/SD_card/lib/modules/

 

[scorpio16v]

Got a problem. Things, I've done.

sudo mkdir /media/mmcblk0p1/lib/boot


sudo cp /boot/uImage-3 /media/mmcblk0p1/boot/uImage


sudo cp /lib/modules/3.2.21/ /mmcblk0p1/lib/modules/

the last one gives me a

omitting directory '/lib/modules/3.2.21'

edit


OK Google isn't evil and gives the answer

sudo cp -r /lib/modules/3.2.21/ /mmcblk0p1/lib/modules/

but Ubuntu stopps with the same error message

 

[Linux-SWAT]

Strange.


Maybe :


sudo cp /boot/uImage-3 /media/mmcblk0p1/boot/uImage-3

 

[scorpio16v]

No, it gives me a

/lib/boot/uImage not found!
Wrong Image Format for bootm command


ERROR: can't get kernel image !

Even if I

sudo cp /boot/uImage-3 /media/mmcblk0p1/lib/boot/uImage

 

[Linux-SWAT]

Check the boot.txt or autoboot.txt at the root of the SD card.


Post the content here.

boot.txt

setenv bootargs debug root=/dev/mmcblk0p1 rw rootdelay=2 vram=6272K omapfb.vram=0:3000K
ubi part rootfs


ubifsmount rootfs


ubifsload 0x82000000 /lib/boot/uImage


bootm 0x82000000

 

[Linux-SWAT]

try to change this line :


ubifsload 0x82000000 /lib/boot/uImage


into


ubifsload 0x82000000 /boot/uImage


or, if it doesn't work:


ubifsload 0x82000000 /boot/uImage-3


of course, ensure you have /boot/uImage and /boot/uImage-3

 

[scorpio16v]

Ah, I'm in.


Last one starts the kernel.


Thank you for your help.


So, back to my former problem with the printer setup. The Password and Keymanager wants an authentication.

 

[Linux-SWAT]

That probably can be fixed by removing some .folder, but i don't know which one.


Maybe try to create another account and log in with it ?

 

[scorpio16v]

Yes, you were right. It works now.

Thank you all of you, now I got it working, too. As others may come across this thread,


this is what my boot.txt looks like (installed on first partition):



setenv bootargs debug root=/dev/

mmcblk0p1

rw rootdelay=2 vram=6272K omapfb.vram=0:3000K




ubi part rootfs




ubifsmount rootfs




ubifsload 0x82000000

/boot/uImage-3




bootm 0x82000000

Sadly, the Wifi does NOT work in Ubuntu with the recent SuperZaxxon Final.


Everything else looked good, I like Unity on the pandora although I would not use it on the desktop.


It was also much easier than installing (Pan-)Debian.


I hope for an update now :rolleyes:

Thanks for writing that down. The kernel location has changed with the latest firmware causing the original boot.txt to fail.

Sadly, the Wifi does NOT work in Ubuntu with the recent SuperZaxxon Final.

Also a kernel problem. As the kernel changed new modules are needed. I don't know when I will get around to updating the image, but I guess you should be able to get it to work by using P-Boot. This will make the modules from NAND accessible when booting from SD/USB/NFS. This should hopefully make WLAN work.

I'd say Xfce, to get consistency with Zaxxon.


For memory usage, i don't know which one if the best.

2x for xfce or KDE. Ubuntu 12 can eat a whole X86 CPU by itself just for the Unity junk.


xfce is actually the least 'hogish' of them. My ideal would be Linux Mint XFCE or KDE - it shares the primary repository of Ubuntu - and gets all of the software, but has a MUCH cleaner user interface.

lxde?
