ลง ScratchBox สำหรับพัฒนา Nokia N770

Submitted by sake on Fri, 01/02/2009 - 17:17

ครั้งก่อน ได้ลง OS 2008HE ไป แต่ไม่ปลื้ม เพราะว่า พอใช้ wireless แล้วเปิดเว็บ เกิดอาหารแฮงค์ รีบูตตัวเองบ่อยครั้ง
เลยโหลด OS2007HE มาลงเหมือนเดิม สุดท้ายก็เหลือปัญหาภาษาไทย ที่ต้องจัดการ เอาไว้เขียนตอนหน้าละกัน

เริ่มต้น ต้องลง scrachbox ซึ่งเป็น development toolkit ตัวหนึ่ง สำหรับ cross compile โปรแกรมต่าง ๆ ลงบน embeded device โดยที่ตัว Maemo และ Nokia ได้สนับสนุนการทำงานโดยมี sdk เสริมเข้ามา
เท่าที่เพิ่งลองเล่น ข้อดีอีกอย่าง คือสามารถ emulate ได้เลยทันทีก่อนไปลงเครื่อง สะดวกสบายพอสมควร

สำหรับ OS2007HE ที่ลงนั้น ใช้ Maemo 3.1 หรือ bora เครื่องที่ผมใช้เป็น Ubuntu8.10 ครับ

ไปที่ http://repository.maemo.org/stable/3.1/ เพื่อโหลดสคริปในการติดตั้งมา โดยสคริป จะดาวน์โหลดตัว gz มา แต่จริง ๆ สามารถใช้เป็น .deb ได้ แต่ที่ผมลงแล้วรู้สึกเพี้ยน ๆ เลยลงแบบ gz ดีกว่า

sake@sake-laptop:~/project/Embeded/N770/maemosdk$ wget http://repository.maemo.org/stable/3.1/maemo-scratchbox-install_3.1.sh
sake@sake-laptop:~/project/Embeded/N770/maemosdk$ sudo ./maemo-scratchbox-install_3.1.sh -u sake -s /scratchbox
This script will install Scratchbox 1.0.7 'apophis' release to your computer.

Running first time script.
Do you want to use sudo mode? [yes/no] (no): Give the name of the scratchbox group (sbox): Stopping Scratchbox: umount, binfmt_misc.
Starting Scratchbox: binfmt_misc, mount.
Now you should add one or more users with /scratchbox/sbin/sbox_adduser
Adding scratchbox user 'sake'.
ผู้ใช้ `sake' ได้เป็นสมาชิกของกลุ่ม `sbox' นี้แล้ว
Scratchbox user account for user sake added
Installation was successful!
----------------------------
You now have Scratchbox 1.0.7 'apophis' release installed.
Scratchbox cannot be run as user root. Instead, use your normal login
user account. Add additional scratchbox users and sandboxes with the
following command (outside scratchbox with root permissions):
# /scratchbox/sbin/sbox_adduser USER yes
Running this command will create sandbox environment for that user and
add user to the 'sbox' scratchbox user group.
You will need to start a new login terminal after being added to the
'sbox' group for group membership to be effective.
Scratchbox service must be started for CPU transparency to be functional.
Run the following command (outside scratchbox with root permissions):
# /scratchbox/sbin/sbox_ctl start
Add this command to e.g. /etc/rc.local file to start scratchbox service
at boot time.
Login to scratchbox session using the following command (as user):
$ /scratchbox/login
Refer to scratchbox.org documentation for more information re scratchbox:

จากนั้นทำการโหลด sdk maemo มาโดยใช้สคริปเช่นเดียวกัน

sake@sake-laptop:~/project/Embeded/N770/maemosdk$ wget http://repository.maemo.org/stable/3.1/maemo-sdk-install_3.1.sh
sake@sake-laptop:~/project/Embeded/N770/maemosdk$ bash maemo-sdk-install_3.1.sh

Installation was successful!
----------------------------
IMPORTANT! Please read this.
You now have the maemo 3.1 'bora' installed on your computer.
You can now start your maemo SDK session with /scratchbox/login and
then select your target with 'sb-conf select SDK_ARMEL' for armel
target or 'sb-conf select SDK_X86' for i386 target.
If you have any problems with targets' package databases, you can try
running 'fakeroot apt-get -f install' on your scratchbox target.
This command will try to fix any problems with the package database.
Even though the SDK was successfully installed, the installation process
was unable to run 'apt-get update' inside the installed targets in order
to update the local package database. This could be due to a error in
network configuration inside scratchbox. A common causes are incorrect proxy
settings and the 'hosts' line in /scratchbox/etc/nsswitch.conf.
For the 'hosts' line in /scratchbox/etc/nsswitch.conf the following should
usually be enough:
hosts: files dns
Once network connections inside scratchbox are working, you should run
'apt-get update' on both targets.
Nokia EUSA binaries
-------------------
The package maemo-explicit is a metapackage of Nokia EUSA licensed
binaries which can be installed to scratchbox targets. It is highly
recommended to install this package on both targets to ensure a fully
working system.
If you want to install these, login to scratchbox (see commands above)
and run the command 'fakeroot apt-get install maemo-explicit' for both
armel (SDK_ARMEL) and i386 (SDK_X86) targets.
Happy hacking!

หลังจากนั้น เราเริ่มเข้าใช้งาน scratch box กันครับ

#/scratchbox/login
Welcome to Scratchbox, the cross-compilation toolkit!
Use 'sb-menu' to change your compilation target.
See /scratchbox/doc/ for documentation.
[sbox-SDK_X86: ~] >

เราสามารถเปลี่ยนระหว่าง host กับ target ได้ โดย

[sbox-SDK_X86: ~] > sb-conf select SDK_ARMEL
[sbox-SDK_ARMEL: ~] >
[sbox-SDK_ARMEL: ~] > sb-conf select SDK_X86
[sbox-SDK_X86: ~] >

ตัว sdk ของ maemo นั้น แนะนำให้อัพเกรด เป็น version ใหม่ คือ 3.2 สามารถใช้ apt ในการปรับปรุงได้เลยครับ

[sbox-SDK_X86: ~] > apt-get update
Err http://repository.maemo.org bora/free Packages
Could not resolve 'repository.maemo.org'
Err http://repository.maemo.org bora/free Release
Could not resolve 'repository.maemo.org'

เกิดปัญหาขึ้น เนื่องมาจากการค้น DNS ที่คัดลอกมาจาก /etc เราสามารแก้ไปได้โดยไปที่นอก scratchbox แล้วแก้ไฟล์ /scratchbox/etc/nsswitch.conf
แก้ให้บรรทัด
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
ให้เป็น
hosts : file dns

ลองใหม่ ผ่านแล้ว เริ่มอัพเกรดได้ ต้องทำทั้ง host และ target

[sbox-SDK_X86: ~] > apt-get update
[sbox-SDK_X86: ~] > PAGER=less fakeroot apt-get dist-upgrade
[sbox-SDK_X86: ~] > sb_conf select SDK_ARMEL
[sbox-SDK_ARMEL: ~] > PAGER=less fakeroot apt-get dist-upgrade
sb-conf select SDK_X86
...
mmap: permission denied when building
dpkg: error processing /var/cache/apt/archives/maemo-af-desktop_2.9.99.25-1_armel.deb (--unpack)

เกิดปัญหาในขั้นตอนที่สอง เราสามารถแก้ไขได้ โดย ปิด vdso และ limit memory map ให้เหลือ 4096 แทนค่ามาตรฐาน 65535

[sbox-SDK_ARMEL: ~] > echo 0 | sudo tee /proc/sys/vm/vdso_enabled
[sbox-SDK_ARMEL: ~] > echo 4096 | sudo tee /proc/sys/vm/mmap_min_addr

จากนั้น อัพเกรดอีกครั้ง จะพบว่า สามารถลงได้เรียบร้อย

จากนั้น เปิดเทอร์มินอลมาลง xserver-xephyr สำหรับรัน X อีกตัว และให้ scratchbox ติดต่อ และ

sake@sake-laptop:~/project/Embeded/N770/maemosdk$ sudo apt-get install xserver-xephyr
sake@sake-laptop:~/project/Embeded/N770/maemosdk$ Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac

และเรียกสคริปที่ scratchbox ให้เริ่มทำงาน gui
