MeeGo 1.1 for NexusOne status part2 and how to work(Using microSD and No fastboot! You can also dualboot both of MeeGo and Android).

Sun, 07 Nov 2010 02:49:00 +0900

As you see, Here is about MeeGo 1.1 can boot on NexusOne from microSD via fastboot.

Part1: http://blog.mitsutaka.org/2010/11/meego-11-for-nexusone-status-and-how-to.html

As I referred at LinuxCon Japan, Next step is standalone boot. So it’s complete replacement. Android => MeeGo. BTW, The slide of LinuxCon Japan is the following.

Warning: APPLY THIS AT YOUR OWN RISK!

I replaced boot.img the Android to MeeGo. But boot partition(/dev/mtdblock2) is too small. This block only can write data about 2.5MB. So It can’t put fully rootfs or intelligent initrd. then boot.img(recover.img) is required zImage and initrd. But zImage only booting has already been proven. So It’s ok that we prepare zImage and empty initrd.

MeeGo 1.1 for NexusOne status and how to work(Using microSD and Boot vi fastboot).

Wed, 03 Nov 2010 18:05:00 +0900

Updated on 20101107(kernel build, kickstart file, dialer screenshot, fdisk /dev/mmcblk0)

Part2. Single boot: http://blog.mitsutaka.org/2010/11/meego-11-for-nexusone-status-part2-and.html

As you know, MeeGo could be worked on the NexusOne. It was v1.1 development release that time. Then I tried if MeeGo 1.1 final release could work on it. Of course, It could be work. and We’ve made it more responsive to running.

LinuxCon Japan 2010 my summary and review

Tue, 05 Oct 2010 01:08:00 +0900

LinuxCon Japan is the premiere Linux conference in Asia. Attending many core open source developers, kernel hackers, administrators, users and so on. It’s an important opportunity for open source contributors. So this is my summary and review.

About my session. It’s my first time presentation in English. Actually I had prepared three months. First, I’m not a native speaker. don’t speak English well. So it needed. Second, My presentation was a plan to port the MeeGo to a device. When I sent a CFP, I didn’t have anything. It was challenge. Then result was so good. MeeGo could work on the NexusOne. I was able to communicate this possibility. Of course, this plan has many issues.

MeeGo 1.1 Development Release(1.0.90.1.20100831.1) for N900 status

Mon, 13 Sep 2010 10:57:00 +0900

As you know, MeeGo 1.1 Development Release(Nightly build) has been released. I saved some log files on my N900 when it was booted by microSD.

I used in the following files.

meego-handset-armv7l-n900-nokia-proprietary-1.0.90.1.20100831.1-mmcblk0p.raw.bz2

meego-handset-armv7l-n900-nokia-proprietary-1.0.90.1.20100831.1-vmlinuz-2.6.35.3-5.2-n900

You can get this image from http://tablets-dev.nokia.com/meego-codedrop.php on which you need your N900 product ID.

BTW, N900 image can display the Handset UX. Also rotation can be worked.

MeeGo kernel was paniced on the N1. then I used android kernel was built by myself.

X.Org doesn’t work yet.

MeeGo 1.0 for N900 status

Thu, 27 May 2010 18:50:00 +0900

As you know, MeeGo 1.0 has been released. Netbook has the User Experience then you can test that using image on your netbook. But N900 and IVI image has no UX. They seem to be development release in position :(

I have a time now, so I output dmesg on my N900 when it was booted by microSD and temporaly boot of kernel.

I used in the following files.

meego-n900-open-armv7l-1.0.0.20100525.1-sda.raw.bz2 ( bzcat xxx.bz2 | dd of=/dev/sdX(microSD) bs=4k)

About MeeGo, MeeGo Netbooks UX screenshots

Thu, 08 Apr 2010 03:43:00 +0900

As you know, MeeGo codes has been opened on the end of March. You can get ia32/arm RPMS/SRPMS now.

http://repo.meego.com

But currently User eXperience doesn’t published. MeeGo community promised to release at Stard of April. And then, The promise was carried out :-) But we can only boot up and see console screen. There were some opinion to this activity on MeeGo mailing list. For example, “User interface has not been released. so It’s not keeping promises”.

Moblin vs Chrome OS

Sat, 28 Nov 2009 09:10:00 +0900

I compared Moblin 2.1 and Chrome OS before time.

Project page Moblin 2.1: http://moblin.org Chrome OS : http://www.chromium.org/chromium-os

Kernel Moblin 2.1: 2.6.31(-netbook, -ivi, -menlow, -mrst) Chrome OS : 2.6.31(-chromeos-intel-menlow) but It isn’t included psb driver Currently, I think this kernel is for netbooks, CULV laptops

Base distribution Moblin 2.1: Original Chrome OS : Ubuntu Karmic

Kernel parametor Moblin 2.1: vga=current quiet root=/dev/sdx (no initrd) Chrome OS : (USB) quiet console=tty2 initrd=initrd.img init/sbin/init boot-local rootwait root=LABEL=C-ROOT ro noresume noswap i915.modeset=1 loglevel=1 (HDD) quiet console=tty2 init/sbin/init boot-local rootwait root=/dev/sda ro noresume noswap i915.modeset=1 loglevel=1

snd-intel-hda.c

Sat, 09 Aug 2008 04:26:00 +0900

あるH/Wのサウンドコーデックが見えないのでkernelを追ってます。もしかするとH/Wの問題かもしれません。。。あるべき変数のビットがたっていないのH/Wの接続PIN位置がずれているように感じます。

なぜviからemacsへ変える決心を？

Mon, 19 Nov 2007 10:02:00 +0900

会社の中にkernel hackerがいるのですが、ある日linuxの/procについていろいろ教えてもらっていました。その人のモニタを見ながらいろいろしていたのですが、emacsを使っていました。linux kernelのソースコードを一緒に読んでいたのですが、バッファの使い方が非常に高速でびっくりしました。しかも自分向けにカスタマイズしたemacs(emacs本体)を使っているんだそうです。やはり次元の違う方でした。

Linuxでファイル暗号化

Mon, 01 Oct 2007 19:53:00 +0900

kernelの機能でdm-cryptというものがあります。ファイルシステムのファイル内を暗号化することができ、比較的簡単に使えます。

ファイルタイプのファイルシステムの場合はloopbackデバイスを経由してやり取りすることになります。redhat系で代表的なのは以下のパッケージで利用することができます。

開発環境と運用環境はやっぱり別?

Mon, 03 Sep 2007 20:44:00 +0900

開発環境はMacbookでも十分に使えます。Linux kernelのコンパイルもそこまで遅く感じません。

ターミナルを卒業したい

Fri, 12 Jan 2007 19:29:00 +0900

ターミナルを使い続けて１年以上になりました。xterm, kterm, gnome-terminalなどいろいろ使ってみましたが、文字コードを使い分ける時があるのでgnome-terminalが一番使いやすいです。MacOSXではもちろん「ターミナル」です。ほとんどgnome-terminalとかわりませんが。

今年の目標

Wed, 03 Jan 2007 07:48:00 +0900

今年の目標を列挙します。

ruby on railsを使いこなす。
linux kernel日々勉強。
英語日々勉強
とあるコミュニティに参加
海外デビュー?

などいろいろ。とにかくがんばります。
