/dev/vmmon error

When I start VMwarePlayer 2, error occur could not find /dev/vmmon.
In google, many people say "use vmware-config.pl", But mostly they do it as same as casting spell.
Also my VMware has not that perl file.
Maybe depend on user that boot VMwarePlayer and load module list.(need more debug myself)
Anyway,load vmmon.ko then ok.

1.check where is my vmmon.ko
# vmplayer
then it show vmmon.ko path.
2.load it
# sudo insmod _that_path_vmmon.ko
3.run VMwarePlayer

Error when reading rootfs

Embedded linux on SD card, Hiding problems in many case as doubt.

• sometime kernel could not boot

Kernel panic - not syncing: No init found, Try passing init= option to kernel".

• sometime read SD card

SD card Buffer I/O error.

• sometime dd command could not done

read error or write error

Please consider it before doubt your embedded linux system.
1st,that kernel panic is evidence u-boot,grub,any boot system are maybe ok.
2nd,try mkfs against rootfs partition and write rootfs all again.
3rd,change SD card writer that using write rootfs.

In my experience mostly SD card writer are problem.
Error occur while dd command, Usually SD card problem. I used many SD card even famous brand.
But how do you believe it?

There is much much illegal copy brand.

It is little help to choice with R mark or not when you purchase SD card.
It is much case in dd command error that using without R mark SD card.
By the way how weak SD card...

Gumstix Overo Fire!!!

But it is not only for overo issue. I never think ANTENNA is so much important in very close range.
When I try check wifi chip RT2870, It is still not work completely.
Anyway Fire:88W8686 needs ANTENNA even 30cm radius from AP.

And headache cross compile RT2870.
Change Makefile like that,Hope it will help for another too.
I used bitbake, So better use that tool chain for cross compile. Because bitbake already gitted kernel headers and build tool chain.
For example, little change RT2870's Makefile.
in ~/tmp/work dir there is source for build and ~/tmp/cross dir there is Tool chain.
But end of line should be "arm-angstrom-linux-gnueabi-", compiler will attach on that end.

ifeq ($(PLATFORM),PC)
# Linux 2.6
LINUX_SRC = ~/overo-oe/tmp/work/overo-angstrom-linux-gnueabi/linux-omap3-2.6.31-r51/image/lib/modules/2.6.31-omap1/build
LINUX_SRC_MODULE = ~/overo-oe/tmp/work/overo-angstrom-linux-gnueabi/linux-omap3-2.6.31-r51/image/lib/modules/2.6.31-omap1/kernel/drivers/net/wireless/

endif

'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n'
that version doesn't work in arm... still I am testing.

Bitbake how to rebuild easy

My proposal is TAKE SNAP SHOT.

When change foo.config for configure.
Bitbake does not rebuild include that reconfigure pkg.
For example, When add some recipes to ~/images/omap3-console-image.bb.
1st build,that added recipes include for deploy images.

But

,when need reconfigure again for that. 2nd times,never include what you want.(from my experience).
It is sure rebuild by rm -rf tmp, But it will make again soooooooooooooo long building time.
My Idea is use VM.(many people use it,when developing)
It is best use-case that TAKE SNAP SHOT since VM take snap shot history ever(maybe), Just build simple omap3-console-image then Take snap shot and after that easy to add recipes,reconfigure,rebuild... also faster.

C++ Associativity

When reading c++ code, find interesting.
If input 0 then num1 is 5 else num1 is input number.

#include    

     int
 main ( )
 {
     int num1;
     std::cin >> num1;
     num1 || (num1 = 5);
     std::cout << num1 << std::endl;
     return 0;
 }

If input 0 then num1 is 0 else num1 is always 5.

#include    

     int
 main ( )
 {
     int num1;
     std::cin >> num1;
     num1 && (num1 = 5);
     std::cout << num1 << std::endl;
     return 0;
 }

interesting.

C++ and C setting for VIM

OmniCppComplete & C/C++ IDE

1.get src.

ctags

c.vim : C/C++ IDE

OmniCppComplete : C/C++ omni-completion with ctags database

2.setup ctags

# tar xzvf ctags-XXXX.tar.gz
# cd ctags-xxxx
# ./configure
# make
# make install
when install,should be root or user has permission.

3.setup vim plugin

# mkdir ~/.vim
# cd ~/.vim
# unzip
# unzip

4.add .vimrc

# vim ~/.vimrc
---add this below 2 lines---
filetype plugin on
set nocompatible

5.activate OmniComplete

# vim foo.cx
:helptags ~/.vim/doc

Then now able to do this functions.
OmniComplete
Adding file header
Adding function/frame comment
Including default code snippet
Performing syntax check
Reading documentation about a function
Converting a code block to comment, and vice versa

redmine & git repo on debian

1.setup redmine

普通にrubyの環境があって、passengerが入ってて、redmineが/var/wwwの下に展開されています。
サーバのホスト名:base08。
セットアップしているマシンのユーザがtknv。

#/etc/apache2/httpd.conf
LoadModule passenger_module /home/tknv/.gem/ruby/1.8/gems/passenger-2.2.4/ext/apache2/mod_passenger.so
PassengerRoot /home/tknv/.gem/ruby/1.8/gems/passenger-2.2.4
PassengerRuby /usr/bin/ruby1.8

PassengerDefaultUser www

ServerName base08
DocumentRoot /var/www/redmine/public

で、redmineで使用するdbの準備が完了していれば、http://base08でredmineが表示されるはず。
表示されないようだったらサイトで確認。
サーバで/var/log/apache2のログを見てもおかしいところがなければ、redmine/tmpのパーミッションが強すぎだったり、666では起動する。または、/etc/apache2/.htaccessファイルがあっていないとか、、、

2.git リポジトリーを立てる。

このサイトが参考になります。
概要:ここで作成したgitユーザがこのbase08ホストで、gitのリポジトリーを立てたり、アップデートしたりします。
注意は説明で行われている、gitリポジトリーを使用するユーザ、gitユーザもbase08ホストで使用しますが、通常業務(趣味ではやらない)で使用するほうで、gitosisの設定を行います。
下記ユーザのマシンでの設定

#~/gitosis-admin/gitosis.conf
[gitosis]

[group gitosis-admin]
writable = gitosis-admin
members = aaa@TKNV bbb@bbc usr1@base08 root@base08

[group dev-Ateam]
writable = project1 project2 project-foo project-wow
members = aaa@TKNV tuka@REP USER1@thinkpad-x300 usr1@base08 root@base08 git@base08

# git@base08が今回の肝です。

[repo project1]
gitweb = yes
owner = tknv@amateras
description = module for UI and support Ajax

大事なのはgit@base08

アカウントをredmineで登録したいリポジトリーのグループに入れておくこと。
あとは、リンクにあるように、/gitosis-admin/keydirに、git@base.pubのように、sshの公開鍵を入れて、gitでサーバにプッシュ。必要なユーザ分、全部おこなう。

3.サーバ上でどうやって、gitリポジトリーを作成しpushのたびに更新するか。

ここ参考になります。しかしながら、ネットにある大抵のHowToは簡単には最近、うまくゆかない。こちらのスキルレベルもあるが、こんだけユーザが多いと、ゴミ情報がたくさん、また、最近は新しいこうゆうテクノロジーが出てくると、とにかくやってみて(やればいいのだが、未検証もあり)サイトにアップする人が多く、間違えもそのままコピペしていたり、、、で

#~/home/git/repositories//hooks/post-update
export GIT_DIR=/home/git/checkout//.git

pushd /home/git/checkout/ > /dev/null
git reset --hard
git pull
popd > /dev/null

WORKDIR="/home/git/checkout/"

/usr/bin/git-update-server-info

unset GIT_DIR

で、先のサイトにもあるが、Don’t forget to create a _local git copy_ (via git clone git@localhost:.git in /home/git/checkout (or whatever folder you prefer)
しかし、このままでも、まだ、無理で、もう2つやることが必要で、まずは、

1.先の今回の肝、git@base08がこの、cloneした、ソースのユーザになっている必要がある。
2.ssh-agentでこのgit@base08ユーザの秘密鍵の方を登録して、パスワード認証を無しにする必要がある。

チェックリスト

• git@~ ユーザがredmineでブラウジングしたいgitリポジトリーのアクセス許可グループに入っているか？(gitosis.conf)
• git@~ ユーザのsshの秘密鍵がサーバ(redmineとgitリポジトリのある)にてssh-agentで追加され、パスワード認証が不要になっているか？
• サーバ(redmineとgitリポジトリのある)の/home/git/checkout/のユーザがgit@~ であるか？
  

勘違いでした。
git clone で問題ない、、、

Debian Enable IBM embedded bluetooth

Bluetooth

Works out of the box using the bluetooth and hci_usb driver. The laptop's Bluetooth device is USB-attached internally and shows up in lsusb as:

$ lsusb
Bus 003 Device 004: ID 1668:0441 Actiontec Electronics, Inc. [hex] IBM Integrated Bluetooth II

The device is not enabled per default though (which is a good thing), you can enable it like this:

$ echo enable > /proc/acpi/ibm/bluetooth

Disabling is equally simple:

$ echo disable > /proc/acpi/ibm/bluetooth

After that, you can use hcitool / hciconfig etc. as usual, and/or enable more related stuff with /etc/init.d/bluetooth restart.

Computers,cars and motorcycles.

For example, when since 80's motorcycle or car is broken,,,

• The coil was broken. => Want a coil => I want to buy only coil => There is only Assy, no choice. And should to get a combined order. => Will take a heavy flywheel and coil.
• The car window open switch was a broeken. => I want to buy a switch => There is only Assy, no choice. And should to get a combined order. =>Will take all electrical system is on the inside of the door.
• Ignition timing is wrong. => CDI problem. => Impossible repairs => Exchange.

For example, when the old 60's motorcycle or car is broken,,,

• The coil was broken. => Want a coil => Search => To replace the coil.
• The car window open switch was a broeken.(Maybe no electric window open) => Adjust or replace the gear.
• Ignition timing is wrong. => Something wrong with the governor. => Re-adjust or replace the timing capacitor.

For example, Microsoft WindowsXP,,,

• When Excel often down. => I do not know. => Excel send report, But MS does not send any reply to the report, even fell frequently. => Re-install it.Because paid soft,don't want waste.
• When Blue back. => Not start. => I do not know. => MSN is going to the site, the comments that have rotation spots to hit similar problems. (Why MS does not support by phone?)
• When IE8 has been updated by automatic(People usually think so). => Can not browse some site. => Can not be downgraded. => Probably reinstall windowsXP.

For example, GNU/Linux,,,

• When OpenOffice down. (Sometime A little heavy, But never down) => So what the hell(This is free). => Re-install.
• When Kernel panic on wake. => Not start. => I do not know. => Ask for help from the community. Usually can find answer.
• When FF 3.5 is an updated itself. (But does not update without expressly) => Can not browse the site occurs. (Not currently), some plug-in is unusable. => Give up pulg-in or downgraded.

I am not saying Linux is old, Mostly Linux has the User. Microsoft has the Customer. It is your money that for supporting.

Who make good software free ! Although Bill Gates is saying. But paying money without support. Who attention to pay ?

Also, Now increaseing people leave for be freedom from Microsoft product net even pay.

The Delight of old cars and motorcycles are feeling that old maker build that fine and strong with builder pride and enjoy my own repairs and the custom, because it is able to be attempted understanding the mechanism.

This is open source in GNU/Linux. Able to read the source, you can try to understand. Analysis of electron injection program the ROM to try to tune in, here's Linux side. It was tuned to the ROM is replaced, this is a windows side and they want.

CDI will be replaced as maker say the manufacturer has failed. When strange Governor, who will happily tell us how to do, of course able to understand it yourself too. Because you can open.

There are some differences work and hobby. But we should have no stress.

I want be surrounded by known and open things.
