Note: Work with Meteor and NodeJs on Ubuntu 14.04

Posted in Works with tags , , , on 2017 年 01 月 16 日 by Kun-Yi

去年某個案子開始用Nodejs/Meteor 不過是北歐的合作廠商負責的 我還是只負責底層 BSP porting 用的是Yocto Distribution 本來案子被我很快的呼嚨完客戶很快的就量產 但是技術債就是這樣遲早都要還 經過半年後 客戶發現某一部份功能不太穩定 希望我這邊重新看看可不可以修正

結果卻發生怎樣都沒辦法build meteor package 重新裝了 meteor/build-essential/nodejs … 等等
還是 build failed 跟之前作案子時完全不同, 經過幾小時嘗試各種方式 然後去看build log 只知道某些 npm package 安裝 failed然後又重新裝各種 nodejs 0.10.x/npm/node-gyp … 還是無法解決 >_<

直到我重新review host 上的 gcc version 才發現目前default 用gcc-4.9, 起因是前幾周在測試 Qt5.6 ~ Qt5.8/Boot2Qt 等等時, 它需要切換到gcc-4.9 配合新的語言標準才行,

但是此時卻發生了npm install packages failed後來透過 sudo update-alternatives –config 把gcc 切回gcc 4.8 果然解決問題

 

Tips:
Debug 中 學到下列
cd ~/.meteor/
ls -al可以看到安裝的meteor version
meteor->packages/meteor-tool/<RELEASE>/<PLATFORM>/meteor
curl https://install.meteor.com > meteor.install
vim meteor.install # 可以去找RELEASE 改成想要安裝的版本, 我自己的案子目前建議還是用 “1.3.2.4″ 目前抓到的應該是 “1.4.2.3″
修改過後用 cat meteor.install | sh 就可以安裝了

Note: Test build Legato Platform of Sierra on Ubuntu 14.04

Posted in Hardware, Works, 未分類 with tags on 2015 年 12 月 29 日 by Kun-Yi

只需要在Sierra Wireless 上註冊帳號就可以下載他的 Source code
它現在採主流 Embedded Linux 的開發環境 Yocto Project,解開後很簡單只需下 make 就可以完成 喔對了網頁上會寫要裝哪些套件成功 build code

但是如果按照這樣的步驟會發現有兩個 package 會出現問題 原因是他在bb 的function 中呼叫了 bash 的內建函式 而bb是呼叫/bin/sh 在 Ubuntu 上預設的 sh 是dash 所以會不能正確執行, 需要做一個work around 當然你也可以手動砍掉symolically 在重新建立連到 bash 的link 也是可行的

 

  • Check that /bin/sh (ls -l /bin/sh) is not symbolically linked to dash. “dash" is a POSIX compliant shell that is much smaller than “bash" — however some broken shell scripts still make use of bash extensions while calling into /bin/sh. To work around this issue call “sudo dpkg-reconfigure dash" and select No when it asks you to install dash as /bin/sh.

 

WorkNote: git-daemon-run & add remote repository to fetch

Posted in git, Works on 2012 年 05 月 29 日 by Kun-Yi

Host A, IP:192.168.10.4 ( fetch remote repository )
Host B, IP:192.168.10.5 ( remote repository, have a branch “uPad" )

First on Host B install git-daemon-run service (on Ubuntu/Debian) and follow the below steps.

read /usr/share/doc/git-daemon-run/README.Debian document, the article describe how do to setup a git daemon on your computer.

1. sudo ln -s ~/kernel/android-3.0/.git /var/cache/git/android-3.0.git  # create a syminks for git-daemon-run
2. touch ~/kernel/android-3.0/.git/git-daemon-export-ok  # create a tag file for git-daemon-run
3. su sv restart git-deamon  # restart git-deamon-run service

On Host A fetch the git repository step

5. git remote add MyRepo git://192.168.10.5/git/android-3.0.git
6. git fetch MyRepo uPad:uPad

Results:

remote: Counting objects: 15, done.
remote: Compressing objects: 100% (8/8), done.
remote: Total 8 (delta 7), reused 0 (delta 0)
Unpacking objects: 100% (8/8), done.
From git://192.168.10.5/git/android-3.0
* [new branch] uPad -> uPad

Note: an UNetbootin tip

Posted in 電腦和網際網路, Works on 2012 年 05 月 15 日 by Kun-Yi

Today I need to setup a host machine to run Ubuntu 10.04 for my work(Android development), so I download an Ubuntu 10.04.4 LTS (Lucid Lynx)  ISO and UNetbootin for Windows version. Just went make a USB disk for Ubuntu install.

But always got a “NTLDR is missing”message when use the Install USB Disk to boot system.

I to try again and again to fixed the issues until reformat the USB Disk and file system change to FAT32.

Keypoint:should check your USB disk is FAT system first when use UNetbootin or similar program

Close WM6 BSP relation workitem, Next workitem

Jun 13. 2008 過了WM6 CIT 的 LTK Certification

今天又收到了 WM 6 AKU1.3.0 的Professional(include Phone Edition) notification mail for CST LTK certification

算是真的將Windows Mobile 告一段落了, 還有可能的事情是Change Phone module/Upgrade size of MDOC(H3)不過這些都做過了, 真的要改也是一兩天的事情而已。

接下來就是 new ATOM 平台的工作

Windows XP/Vista/Linux 32/64bits GPIO/ACPI driver and application for wireless control.

Windows 的AP應該會繼續用 WTL寫.

Linux 的目前想法會寫一個console app + GTK 的wrapper UI 透過 redirection standard I/O 方式, 這樣應該比較容易應付客戶的各種需求

Embedded Controller 的Firmware Modify有P社/I社的Code base, P是Keil A51, I是 Keil C51. 配合Hotkey 定義 add combination key

BIOS 應該是 P社的 MASM + C wrapper to EFI inteface

should need create the following application by myself or outsourcing.

  • Change display resolution application
  • Rotate display oriented.
  • Hotkey manger and launch application.
  • Pointer driver and setting applicaiton(from touch panel/pointer vendor)
  • Hook keyevent on Linux to implement Hotkey manger

Building Mobile Linux image on the platform

建議HW 使用EC的GPIO 不要透過Southbidge的 GPIO, 建立在ACPI的機制上, 將driver單純與單一化, 並且可以用在新的chipset平台上, 不受INTEL的未來規劃影響.

Work Note : WM 6.1 Network Policy & Monitor

Posted in WinCE, Works on 2008 年 08 月 07 日 by Kun-Yi

Finial Network Policy WiFi/Bluetooth items

add RegistryNotifyWindow() to WM_CREATE/RadioManager

add RegistryCloseNotification() to WM_DESTORY/RadioManager

add process WM_USER for registry change notification

Work Note: RIL

Posted in Works on 2008 年 08 月 06 日 by Kun-Yi

SIEMENS – RILDrv v1.2.5.10, MC75 rev 3 or rev4 (Test on rev 3 module)

WM 6 AKU 1.3 Build 20269

症狀:

        有時Power On 開機會發生, GSM Module 燈亮, 但是Today 顯示No Service 過了幾分鐘後, 會顯示 Phone Off, 在Clean boot 時, 特別容易發生。

除錯:

        觀察與比對正常與不正常的 RETAILMSG 發現有時會開不了 "com" port, 判斷是MUXDRV 還來不及建立 COM/DATA/AUX PORT

 

Workaround:

        修改TurnOnModule method 呼叫 OpenPortDevice 時加入 Re-try mechanism (3 times) + Sleep(50)

測試結果:

測試10 times, 觀察到都只發生一次Re-OpenPortDevice 即可成功正確打開GSM Module
