| 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? | 12:21 |
|---|---|---|
| tim | also, is there some kind of live-microsd image? sharp just provides an image, that restores the original state of the machine ... | 12:24 |
| Baybal | eh | 12:40 |
| Baybal | what kind of upgrade you did? | 12:41 |
| Baybal | nikulinpi@gmail.com | 12:41 |
| * Baybal away | 12:41 | |
| tim | Baybal, adapt /etc/apt/sources.list to point to lucid and sudo apt-get dist-upgrade | 12:46 |
| Baybal | hmm | 12:47 |
| Baybal | did you update kernel? | 12:47 |
| Baybal | I think you may have pointed the apt to repository for PC | 12:47 |
| Baybal | I'm sleepy | 12:48 |
| Baybal | email me please | 12:48 |
| Baybal | i'm gonna go bed | 12:48 |
| tim | Baybal, ok ... i'll send you an email ... i guess, the kernel was updated ... | 12:50 |
| tim | mc | 14:05 |
| 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). | 14:07 |
| tim | persia, hm ... see | 14:08 |
| tim | persia, did you manage do to that? | 14:08 |
| 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? | 14:09 |
| 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. | 14:10 |
| 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. | 14:11 |
| 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). | 14:13 |
| 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 | 14:15 |
| 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). | 14:16 |
| 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 .. | 14:17 |
| persia | I've just asked in #ubuntu-kernel, in case anyone knows, but those guys tend to be quiet on the weekends. | 14:18 |
| 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. | 14:19 |
| 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 :( | 14:23 |
| persia | :( | 14:24 |
| 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/ | 14:25 |
| persia | Well, you might want to fix the redirect on kernel.ubuntu.com :) | 14:26 |

| tim | persia, hm ... true ... not easy to port :/ | 14:47 |
| 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. | 14:48 | |
| tim | not easy doesn't mean, not impossible | 14:50 |
| tim | s/im// | 14:50 |
| 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 | 14:55 |
| persia | cwillu: You're able to boot a mainline kernel on a PC-Z1? I was advised this might melt my laptop. | 14:56 |
| 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 | 14:58 |
| cwillu_at_work | (sorry, ran off) | 15:07 |
| cwillu_at_work | and I missed the bit about non-standard hardware too :p | 15:08 |
| persia | I'm not sure it's "non-standard", but just not known to be supported mainline today. | 15:09 |
| 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 :) | 15:10 |
| persia | Sorry: timezone failure :) | 15:12 |
| * cwillu_at_work checks the time | 15:17 | |
| cwillu_at_work | oh, it's even morning | 15:17 |
| tim | hm ... if we would know, what the original version of the kernel was, that sharp was modifying, it would be easier :/ | 15:27 |
| persia | I suspect it's the 2.6.28 BSP from FSL, but I can't be sure. | 15:28 |
| tim | well, it conflicts with very early version of 2.6.28 from the linux-2.6-imx.git tree ... then the sources diverge | 15:40 |
| persia | Ugh | 15:42 |
