Title: Success! Ubuntu + Cacko!
Post by: duo on May 10, 2009, 05:05:51 pm

step 1. Nand restore from trisoft.
step 2. Install Cacko, but don't resize the root partition.
step 3. make a folder on a sd or cf card called /boot/ contents:
           zImage (kernel of your choice. I like EvilJazz's)
           kernel-commandline (what should be here is all over these forums)
           Image.nfo (only used if you use Cortez's kexecboot kernel, not used by Angstrom's)
Step 4. flash multiboot kernel

that's it, should work.
if you want the kernel, placed in nand, mount the root partition as rw, then move the /boot/ folder from sd to nand.

Backstory: Every time I tried to get Cacko to load, I would get a long sting of numbers (memory addresses I think) and finally a kernel panic.

Even though i resized the root partition of Cacko to 32MB, as suggested in the readme; and I had the proper config in kernel-commandline,I kept getting erros.
I noticed that even though i resized the partition, and specified a 32MB partition in the commandline, the mtd partitions were always the same.
00000000-00700000 smf
00700000-03c00000 root
03c00000-08000000 home

doing the math,  i realized that the root partition above is 53MB in size. So I reflashed Cacko again for the N+1 time and this time, instead of resizing the root partition to 32MB, I set it to 53MB and then changed the kernel-commandline to reflect this. Instant success!!!

I try it before. But the kernel of Cacko can not be boot.

I am using C760.

What is the model you are using ? Can you tell more details ?

Thanks!

So after trying forever to get Cacko to boot off of Nand, I finally figured out what the hangup was.

thanks for a very helpful post. I will give dual-boot cacko another go!

Strange!
53MB is not standard root size for akita...I'd expect 58.

original 2.4 cmdline for all Zaurus models ( http://digit.que.ne.jp/visit/index.cgi?59414d41 (http://digit.que.ne.jp/visit/index.cgi?59414d41) ):

Kernel command line: console=ttyS0 root=/dev/mtdblock2          mtdparts=sharpsl-nand:7168k@0k(smf),59392k@7168k(root),-(home)    jffs2_orphaned_inodes=delete EQUIPMENT=0 LOGOLANG=1 DEFYEAR=2006 LOGO=1 LAUNCH=q
Console: colour dummy device 80x30

Have you resized your partition with cacko/pdaxrom installers?

I started over with a nand restore from tri-soft.
flashed cacko
used the nand flash utils from the cacko installer
set the root partition to 32MB
booted into cacko, copied the kernel commandline and then flashed the multiboot kernel.
would not boot into cacko (strings of numbers then kernel panic)
did some math (above)
reflahed cacko, this time set the root partition to 53MB
booted into cacko, copied commandline ...etc
this time cacko booted.

i did not bother to flash the Katastrophos kernel, i just left it in the /boot dir on my sd's cacko partition.

did you guys lose the wallpaper and hard drive mount in cacko after starting it from the multi boot kernel?

My cacko is like that and the wallpaper and mount are gone...

I have successfully mounted back the micro drive from cacko. And I can find the wallpaper back from hdd3, but for some reason I can see it but can't apply it as wallpaper.

Is there some kind of access right issue? Can somebody help?

UPDATE: Everything is working again. problem appears to be a jffs2 issue. when installing packages, install only a couple at a time, then reboot. Should work just fine then. Also, i'm currently using the Angstrom Multiboot kernel for akita and it also is hardcoded for a 53MB root partition.



So now Cacko is acting weird on me. I can't PPP with BT or Connect to Wifi anymore. Plus I can't install anything. Something is up. Am going to try reflashing Cacko.

Also came across this on Yonggun's website  (http://yonggun.tistory.com/67) where he says to use 53MB partition on Nand also for dual boot.

Makes me wonder if Cortez's (Omegamoon) kernel is based on, or shares something with Yonggun's (2or0).
