Dual Booting Pdaxrom And Angstrom?

Yes !!! Please do.

Fromp what I understand, it wouldn't only be possible to dual boot pdaxrom and angstrom, but also to dual boot pdaxrom and pdaxrom !! Two different setups, one one nand and one on microdrive .... I love it    

I already tried the kernel for C3100 posted by svs57(?) in the debian-and-uboot-thread to boot pdaXrom from the microdrive. It works, but I have some issues with the touchscreen (similar to those who own a CXX0 and try to run r198, I believe). But at least it boots and loads X etc.

Really looking forward now ...

Yes Meanie, I would be interested too,
I think it would help a lot of people to test kernels and to debug them bit by bit while still having another system to boot into.  This would probably be the most important devlopment for me trying Angstrom or debian, as I could still use my zaurus without having to reflash.

Well the problem is that quite a fes issues may arrise by the use of different kernels ... here is just a few:
nand flash layout problems,
specific distribution kerlen patches missing can break things like zaurushw,
old-ABI is only experimental OPTION in EABI kernels so not all old-ABI code may run fine on an EABI kernel (even if the option is enabled).

Although I do not like it much currently the solution that would take the least effort for multi boot is kexec with a rare exception of r121+ pdaxrom versions that can share the same kernel (as a matter of fact on my C860 I have r198 in nand and a higly modified r121 in MMC and use just u-boot to select whic one to boot).

Would it be possible to do the same and boot from the microdrive instead ? (I'm looking for a solution to run r198 from microdrive) ?

In theory. I was trying to get Gentoo boot from microdrive, but for some reasons kernel detects partitions after booting (see at emergenc system - I got there "Unknown partiton layout" - same thing I get if when booting from microdrive)

And what about OZ's altboot? I thought it could boot system from other than nand devices...

Yes but I think a special kernel is neaded ... not sute if you can do it with a normal pdaxrom kernel.
You can try and see what happens ....
Use the sd bootable image builder from my home page ... modify it to target a partition on your microdrive and the boot by while pressing "3" ....

Yes, it use kexec, but it also starts rather fast... So maybe it can be useful for dual booting?

Since nobody really answered, I'll do it myself :
It was (is) already possible - no special kernel needed.
(thanks louigi600 !!!)  

Having a lot of fun,

That would be difficult if not impossible : you'd have to mix 2.4 and 2.6 kernels.

Is it possible to boot pdaxii13 from u-boot?  And if not, why not?
I'd like to have pdaxii13 on NAND and a debian system on SD and use u-boot to choose which one to boot.

Let's try to wake up this thread while bitbake is eating all the CPU time

I'm interested in this, but I think the best would be to allow different kernels... That is, either use u-boot to boot angstrom, or altboot to boot pdaXrom. Using altboot + kexec, we could change the running kernel, and if altboot is started soon enough (it was the case when I used the hentges rom on my 5500) the additional boot time won't be a problem.

However, I have not yet a clear enough understanding of u-boot, pdaxrom and angstrom to know which problems would need to be addressed. The last time I changed kernel parameters I had to use the mean old buildroot (I needed a /bin/sh to repair, and there was no altboot at the time...), that tells you how old my knowledge is

I'm willing to spend time on this, any pointer / help / doc is welcome

I had a go at making Angstrom boot of the mmc (like I do for my modded r121) but it was a no go.
I think that there is 2 problems involved:
angstrom kernel seems to have ither no support for ext2/3 (or at least only in modules),
angstrom kernel is ignoring command line parameters passed by u-boot (may need a u-boot patch).

To check out these things one would need the Angstrom kernel sources ... currently I cannot putup the OE build environment to get the sources for me and I've not been able to figure out how to make a Angstrom kernel by starting from a vanilla one.
Is someone could supply ... I'd have a look into it.
