[12:21] <tim> hi ... i've got a sharp netwalker z1 and would like to upgrade the version of ubuntu (it comes with 9.04 preinstalled). after a simple update, it does not boot any more, though ... the device is using redboot as boot loader ... before starting a new attempt, does anyone have experience with this device?
[12:24] <tim> also, is there some kind of live-microsd image? sharp just provides an image, that restores the original state of the machine ...
[12:40] <Baybal> eh
[12:41] <Baybal> what kind of upgrade you did?
[12:41] <Baybal> nikulinpi@gmail.com
[12:41]  * Baybal away
[12:46] <tim> Baybal, adapt /etc/apt/sources.list to point to lucid and sudo apt-get dist-upgrade
[12:47] <Baybal> hmm
[12:47] <Baybal> did you update kernel?
[12:47] <Baybal> I think you may have pointed the apt to repository for PC
[12:48] <Baybal> I'm sleepy
[12:48] <Baybal> email me please
[12:48] <Baybal> i'm gonna go bed
[12:50] <tim> Baybal, ok ... i'll send you an email ... i guess, the kernel was updated ...
[14:05] <tim> mc
[14:07] <persia> tim: Hey: I've a PC-Z1 also.  The issue is twofold: 1) it's hard to find any newer kernels for that device, and 2) it ships with Ubuntu for ARMv5, but lucid is for ARMv7+thumb2, which means one needs to essentially reinstall (and compile a new kernel with the lucid toolchain).
[14:08] <tim> persia, hm ... see
[14:08] <tim> persia, did you manage do to that?
[14:09] <persia> Do which?  Upgrade?  I've not found a newer kernel.
[14:09] <tim> i see
[14:09] <tim> btw, what specifics does the kernel have?
[14:10] <persia> My understanding is that lucid udev, upstart, etc. require features not available in the older kernel.  I've not tried it with the mix, but I wouldn't expect it to work.
[14:10] <persia> How do you mean, what specifics?
[14:10] <tim> certain device drivers etc
[14:10] <tim> the source, that is provided by sharp is essentially the 2.6.28 vanilla kernel
[14:10] <persia> Oh, I don't know the specifics.  The source is available: let me see if I can dig it up.
[14:11] <persia> I'm certain the provided source is the real source.  I know there were some patches that got sent upstream.  I don't know if all the patches got sent upstream.
[14:13] <persia> Any of the "araneo" sources at http://netbook-remix.archive.canonical.com/updates/pool/public/l/linux-fsl-imx51/ would be the correct source for the packages installed on the machine.  I think the sendai kernels are for the newer netwalker (without keyboard).
[14:15] <tim> ah ... i see ... btw, i just checked ... there _are_ some differences between the vanilla kernel and the sharp kernel
[14:15] <tim> i will try, maybe i can port them to a recent kernel version
[14:15] <persia> If you can, that would be *great*!  I'd love to run lucid or maverick on the PC-Z1
[14:16] <tim> persia, i'll do my best ... do you know of any source, how to cross-compile a kernel?
[14:16] <persia> I only know a little about how the kernel packages are compiled, but the kernel team usually hangs out in #ubuntu-kernel, and they can probably answer anything that doesn't get a good response here about how the package works (I think the contents are from Sharp or Canonical or someone, so I wouldn't expect the kernel team to know them well).
[14:17] <persia> We generally discourage cross-compilation in Ubuntu.  I seem to remember some document on the kernel team wiki about cross-compilation, but I don't remember the URL.
[14:17] <persia> You might do a text search on the wiki (but it will take a while).
[14:17] <tim> persia, i'll try ..
[14:18] <persia> I've just asked in #ubuntu-kernel, in case anyone knows, but those guys tend to be quiet on the weekends.
[14:19] <tim> btw, do you know, if there is a git respority for the araneo sources?
[14:19] <persia> I don't know.  I heard some rumours that it wasn't developed in git, so if there is, and the rumours are true, the git repo would be more of a back-application of patches.
[14:23] <tim> hm ... i just found an interesting forum posting from someone, trying to port it to 2.6.31 ... and who gave up because of badly written code :(
[14:24] <persia> :(
[14:25] <persia> http://ime.nu/kernel.ubuntu.com/git?p=amitk/ubuntu-fsl-2.6.31.git;a=summary might have some of it, according to http://pc11.2ch.net/test/read.cgi/linux/1258005134/
[14:26] <persia> Well, you might want to fix the redirect on kernel.ubuntu.com :)
[14:47] <tim> persia, hm ... true ... not easy to port :/
[14:48] <persia> That's what everyone tells me :(
[14:48]  * persia hopes someone will make some new small PC that runs Ubuntu well and works with upgrades.
[14:50] <tim> not easy doesn't mean, not impossible
[14:50] <tim> s/im//
[14:55] <cwillu> honestly, mainline kernels work fine for the most part
[14:55] <cwillu> i.e., unless you actually have hardware that we include the driver for
[14:56] <persia> cwillu: You're able to boot a mainline kernel on a PC-Z1?  I was advised this might melt my laptop.
[14:58] <tim> cwillu, i guess, there is some specific hardware in the machine ... almost 400000 lines of code differ between vanilla 2.6.28 and sharp's
[15:07] <cwillu_at_work> (sorry, ran off)
[15:08] <cwillu_at_work> and I missed the bit about non-standard hardware too :p
[15:09] <persia> I'm not sure it's "non-standard", but just not known to be supported mainline today.
[15:10] <persia> It's certainly widely available in retail channels though.
[15:10] <cwillu_at_work> I haven't had my coffee yet, give me a break :)
[15:12] <persia> Sorry: timezone failure :)
[15:17]  * cwillu_at_work checks the time
[15:17] <cwillu_at_work> oh, it's even morning
[15:27] <tim> hm ... if we would know, what the original version of the kernel was, that sharp was modifying, it would be easier :/
[15:28] <persia> I suspect it's the 2.6.28 BSP from FSL, but I can't be sure.
[15:40] <tim> well, it conflicts with very early version of 2.6.28 from the linux-2.6-imx.git tree ... then the sources diverge
[15:42] <persia> Ugh
