Hi,

the hackers at OpenEmbedded are almost ready to ship a new set of special kexec-enabled 2.6 kernels for all Zaurus machine supported:

c7x0 (SL-C7x0 - SL-C860)
akita (SL-C1000)
spitz (SL-C3xx)
tosa (SL-6xxx)
collie (SL5500)
poodle (SL5600)

These special-purpose kernels are small enough to be flashed on NAND and feature a frambefuffer graphical menu for the selection of the boot media.
Multipartitioned cards and lot of filesystems supported.
Kernel and cmdline reside now in /boot.

THIS IS THE LONG AWAITED SOLUTION FOR BOOTING DIFFERENT DISTROS FROM SD/CF

Release is scheduled for end of December. Stay tuned!

I tried kexecboot on the Akita and Spitz, and it works great.
I'm going to use this for zUbuntu, which makes it work on at least the C3x00,C1000,C7x0,C860...

excellent news indeed. I'm loving the idea of multi-booting cacko and zubuntu!

So , does this take the place of the boot loader? Can I install Kexecboot plus default Sharp ROM, plus another distro to try without losing the use of my default ROM? (I am using SL-6000L.)

I have been trying to get the images in the autobuild directory to boot doing this with no luck, is that because the autobuild images do not include these new kernels? If so, can I just use another set of kernel modules (like the ones zubuntu is using)?

Nevermind, I had formated the partition ext3. Once I formatted it ext2 everything works fine.

Any news here?

I'm waiting for the update because the existing kexecboot does not boot my Angstrom on the internal memory of the CL760 anymore.

see the ubuntu forum, a number of us have graphical multiboot now. make sure you copy your kernel to /boot along with configs, set up /lib/modules etc BEFORE installing the multiboot kernel!

Hi

will the new kexecboot support logical partitions on SD cards? Looks like the current version does not support them

Thanks for the hint -- but the question remains: Are logical partitions supported by the current version and It's a bug that kexecboot does not find the logical parititons on my SD card or are logical partitions not yet supported? If it's not supprted I'll make an entry in the whish list.

regards

The current release supports only 4 mmc peripherals (last is/dev/mmcblk0p3). That's why only 3 partitions are seen.
The new release will fix this too (tested personally).

For /dev/hda, 20 devices are already defined (last is /dev/hda19).

Hope this clears the thing a bit...

Cheers

BTW there is a limit to the number of partitions on mmc devices: 7

http://wiki.openmoko.org/wiki/Booting_from_SD


* The device nodes numbering schema provides minor numbers from 1 to 7 (/dev/mmcblk0p1 ... /dev/mmcblk0p7). Minor number 8 is the next physical device (/dev/mmcblk1). So we're restricted to a maximum of 7 accessible partitions.

* Currently most rootfs' supplies devices mmcblk0p1 through mmcblk0p4. If you want to use extended partitions (5 ...), you need to add those to the udev setup by creating the nodes in /lib/udev/devices/:
