Avoid zombie process
在某些應用中常會需要執行其他的程式,這時候就會需要呼叫fork產生child process並在此執行其他程式.
而當被呼叫的程式執行結束child process也就跟著結束,這時child process就成為zombie process.
if(fork() == 0) { /* Child process*/
/* Run program */
execl("/bin/ntpdate", "ntpdate", "tick.stdtime.gov.tw", "tock.stdtime.gov.tw", (char *)0);
exit(0);
/* zombie process */
}
/* Parent process or error */
wait(0);
zombie process存在的意義是等待parent process來處理child process結束後的事情,例如程式的傳回值.
有兩種方式來避免zombie process
1.明確指出parent process不需要知道child process的結束狀態
在parent process 程式碼中加上
signal(SIGCHLD, SIG_IGN); /* Do not wait for child process */
2.連續fork兩次,藉由結束first child process的方式讓second child process的parent process為pid 1 (通常是 init)
pid_t pid;
if((pid = fork()) == 0) { /*First child process*/
if((pid = fork()) > 0)
exit(0); /* Terminate first child process */
/* Second child process. Run program */
execl("/bin/ntpdate", "ntpdate", "tick.stdtime.gov.tw", "tock.stdtime.gov.tw", (char *)0);
exit(0);
}
/* Parent process or error */

Embedded Linux IPv6 ready logo phase-2
The past month I'm working on IPv6 ready test on an embedded linux platform.
Since the kernel is really old 2.6.10 and I have to do some porting from newer kernel to get IPv6 ready test pass. Last week I finally all pass and below are some tips.
1.The test node (TN) is FreeBSD 7.4 release with v6eval-3.3.2 / v6eval-remotes-3.0 / Self_Test_5.0.0
It's very important that to disable ipv6 autoconfiguration on TN, because the testing suit needs clean ipv6 environment.
To disable ipv6 autoconfiguration, edit /etc/rc.conf and set
ipv6_enable="NO"
then after TN boot, the ipv6 link local address (fe80:X) won't be exist.

This file is really important for self test. It makes the TN to communicate NUT through serial RS232 port. TN can login / logout NUT system even more reboot NUT.
So, find key words below in this file and get it right
$Type="linux-v6";
$Device="cuad0";
$User="root";
$Password="1234";
The TN will detect message from NUT to login / logout. For example "login: " and "Password: ". Also get it right for your NUT's Behavior
# login prompt
%prompt_user = (
...
'linux-v6', 'login: ',
...
);
# password prompt
%prompt_password = (
...
'linux-v6', 'Password: ',
...
);
# command prompt
%prompt_command = (
...
'linux-v6', '(\$|#) ',
...
);
and so on
5.Test TN <-RS232-> NUT
If you can see login screen or promopt, it works
touch /var/log/aculog
chown uucp:dialer /var/log/aculog
chmod 660 /var/log/aculog
cu -l /dev/cuad0
Connected
[root@HL200 ~]$
6.Remote test
To test if TN can login then logout NUT
/usr/local/v6eval/bin/linux-v6/loginout.rmt -o1
HL200 login: root
Password:
BusyBox v1.2.2 (2011.07.20-06:33+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.
[root@HL200 ~]$
[root@HL200 ~]$ exit
7.Run self test
cd Self_Test_5-0-0
make clean
make ipv6ready_p2_host
8.Run parts of self test
There are 5 test sections, you can test separated.
cd nd.p2/
make clean
make ipv6ready_p2_host
Also can test only few items, for example test items 10 to 20
make AROPT="-s 10 -e 20" ipv6ready_p2_host
9.Embedded linux setup.
There are some sysctl for ipv6 need to be set correct.
echo 0 > /proc/sys/net/ipv6/conf/default/forwarding
echo 2 > /proc/sys/net/ipv6/conf/default/dad_transmits
echo 1 > /proc/sys/net/ipv6/conf/default/use_tempaddr
echo 2 > /proc/sys/net/ipv6/conf/default/accept_dad
echo 1 > /proc/sys/net/ipv6/conf/default/optimistic_dad
echo 1 > /proc/sys/net/ipv6/conf/default/accept_redirects
Remember to set promisc and allmulti to ethernet port.
Another tip is to sleep 10 seconds after the ethernet up then go login screen
ip -6 link set lo up
#ip -6 link set eth0 up
ifconfig eth0 up promisc allmulti
echo "Wait 10 secs..."
sleep 10
10.Finally, fix /usr/local/v6eval/bin/unknown/ping6.rmt

LeopardBoard DM368 ffmpeg
For the HD video I need libraries to support video / audio file mux. The ffmpeg is a good choice. With ffmpeg I can save H.264 raw data into mp4 file then play video on PC.
1.Download ffmpeg-0.6.1
Download ffmpeg-0.6.1 and put it in ~/LeopardBoard/DM368
2.Cross compile ffmpeg
I will install ffmpeg into the toolchain sub directory for convenience. My toolchain locate at /opt/arm-2009q1
$ cd ~/LeopardBoard/DM368/ffmpeg-0.6.1
$ mkdir build
$ cd build
$ ../configure --target-os=linux --arch=armv --cpu=armv5te --enable-cross-compile --cross-prefix=arm-none-linux-gnueabi- --prefix=/opt/arm-2009q1/arm-none-linux-gnueabi/libc/usr
$ make
$ sudo PATH=$PATH:/opt/arm-2009q1/bin make install
3.Apply patch to fix Makefile to prevent application link error and add new application video_encode_mp4.
ti-dvsdk_dm368-evm_4_02_00_06_dmai_2_20_00_15_ffmpeg.patch
There will be link error while compile application, so I did some modify to dmai_2_20_00_15/packages/ti/sdo/dmai/apps/Makefile.app
The new application is capable to record HD video and save it into mp4 file
4.Recompile DMAI
$ cd ~/LeopardBoard/DM368/original/ti-dvsdk_dm368-evm_4_02_00_06
$ make dmai
The new application video_encode_mp4 is located at dmai_2_20_00_15/packages/ti/sdo/dmai/apps/video_encode_mp4/linux/video_encode_mp4_dm368.x470MV

4.Now, it's time to encode video from camera. I got mt9p031 (LI-BCM5M03).
If you got kernel log below, the camera is ready

6.There's a application can do H.264 RTP which included in my dmai_2_20_00_15 patch called video_encode_rtp.
This application get frames from camera through VPFE then encoded in H.264 format packeted with H264RTP packet then send to network.
From LeopardBoard DM368
$ cd /usr/share/ti/ti-dmai-apps
$ ./video_encode_rtp_dm368.x470MV -I camera -y 4 -c h264enc -i /dev/video0 -o 192.168.168.72 -p 1234 -e encode -b 2000000
-I camera = camera input
-y 4 = 720P,
-o 192.168.168.72 = Send to 192.168.168.72
-p 1234 = port 1234
-b 2000000 = Bit rate 2000000
I'm decoding the video stream with gstreamer on PC Ubuntu.
$ gst-launch udpsrc port=1234 caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264" ! gstrtpjitterbuffer latency=100 ! rtph264depay ! ffdec_h264 ! xvimagesink
If the video frame sometimes droped, try larger gstrtpjitterbuffer latency = 200 / 300 / 500.

LeopardBoard DM368 running with TI DVSDK
I got LeopardBoard DM368 for a while and get it work with TI DVSDK.
The mt9p031 camera also works and capable of Full HD H.264 encode.
Boot device is SD card.
Below I will show how to do it.
0.Install toolchain
CodeSourcery arm 2009-q3.
See DVSDK download page for detail.
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/index_FDS.html
1.Download TI DVSDK 4_02_00_06
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/exports/dvsdk_dm368-evm_4_02_00_06_setuplinux
2.Install DVSDK 4_02_00_06 into ~/LeopardBoard/DM368/original/
3.Download patch for LeopardBoard DM368
$ cd ~/LeopardBoard/DM368/original/ti-dvsdk_dm368-evm_4_02_00_06
ti-dvsdk_dm368-evm_4_02_00_06_leopardboard.patch
ti-dvsdk_dm368-evm_4_02_00_06_Makefile.patch
ti-dvsdk_dm368-evm_4_02_00_06_dmai_2_20_00_15.patch

$ patch -p1 < ../../ti-dvsdk_dm368-evm_4_02_00_06_leopardboard.patch
$ patch -p1 < ../../ti-dvsdk_dm368-evm_4_02_00_06_Makefile.patch
$ patch -p1 < ../../ti-dvsdk_dm368-evm_4_02_00_06_dmai_2_20_00_15.patch
4.Build everything
$ make
5.Create symbolic link of uImage & u-boot
$ cd psp/prebuilt-images/
$ rm -rf ./*
$ ln -s ../u-boot-2010.12-rc2-psp03.01.01.39/u-boot.bin u-boot-dm368-evm.bin
$ ln -s ../linux-2.6.32.17-psp03.01.01.39/arch/arm/boot/uImage uImage-dm368-evm.bin
$ cd ../..
6.Build SD card
Make sure your SD card device node. For me it's /dev/sdb
$ sudo bin/mksdboot.sh --device /dev/sdb --sdk ${PWD}
The process could be a few minutes...
After the process complete, the SD card is unmount automatically.
7.Fix DVSDK install location
Edit Rules.make
Change this one
EXEC_DIR=$(HOME)/install/$(PLATFORM)
to
EXEC_DIR=/media/ROOTFS
8.Do install everything in root file system
Insert SD card again
$ make install
9.Modify boot.cmd & boot.scr
Edit /media/BOOT/boot.cmd as below
mmc rescan 0
setenv bootargs 'console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw ip=off mem=60M davinci_enc_mngr.ch0_output=COMPONENT davinci_enc_mngr.ch0_mode=720P-60 davinci_display.cont2_bufsize=6291456 vpfe_capture.cont_bufoffset=6291456 vpfe_capture.cont_bufsize=6291456 video=davincifb:vid0=off:vid1=off:osd1=off dm365_imp.oper_mode=0 davinci_capture.device_type=4 vpfe_capture.interface=1 rootwait'
fatload mmc 0 80700000 uImage
bootm 80700000
Create boot.scr
$ cd /media/BOOT
$ mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Execute Boot Script' -d boot.cmd boot.scr
10.Umount SD card and insert to LeopardBoard DM368
Make sure the DIPSW is SD card boot.

11.Fix Alsa probleam
ALSA: Restoring mixer settings...
Configuring network interfaces... No state is present for card EVM
Unknown hardware: "tlv320aic3x" "" "" "" ""
Hardware is initialized using a guess method
No state is present for card EVM
The problem is due to wrong /etc/asound.state
While booting /etc/init.d/alsa-state loads /etc/asound.state if it exist
To fix it, just do
$ rm -rf /etc/asound.state
The mt9p031 camera also works and capable of Full HD H.264 encode.
Boot device is SD card.
Below I will show how to do it.
0.Install toolchain
CodeSourcery arm 2009-q3.
See DVSDK download page for detail.
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/index_FDS.html
1.Download TI DVSDK 4_02_00_06
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/exports/dvsdk_dm368-evm_4_02_00_06_setuplinux
2.Install DVSDK 4_02_00_06 into ~/LeopardBoard/DM368/original/
3.Download patch for LeopardBoard DM368
$ cd ~/LeopardBoard/DM368/original/ti-dvsdk_dm368-evm_4_02_00_06
ti-dvsdk_dm368-evm_4_02_00_06_leopardboard.patch
ti-dvsdk_dm368-evm_4_02_00_06_Makefile.patch
ti-dvsdk_dm368-evm_4_02_00_06_dmai_2_20_00_15.patch
patch
$ patch -p1 < ../../ti-dvsdk_dm368-evm_4_02_00_06_leopardboard.patch
$ patch -p1 < ../../ti-dvsdk_dm368-evm_4_02_00_06_Makefile.patch
$ patch -p1 < ../../ti-dvsdk_dm368-evm_4_02_00_06_dmai_2_20_00_15.patch
4.Build everything
$ make
5.Create symbolic link of uImage & u-boot
$ cd psp/prebuilt-images/
$ rm -rf ./*
$ ln -s ../u-boot-2010.12-rc2-psp03.01.01.39/u-boot.bin u-boot-dm368-evm.bin
$ ln -s ../linux-2.6.32.17-psp03.01.01.39/arch/arm/boot/uImage uImage-dm368-evm.bin
$ cd ../..
6.Build SD card
Make sure your SD card device node. For me it's /dev/sdb
$ sudo bin/mksdboot.sh --device /dev/sdb --sdk ${PWD}
The process could be a few minutes...
After the process complete, the SD card is unmount automatically.
7.Fix DVSDK install location
Edit Rules.make
Change this one
EXEC_DIR=$(HOME)/install/$(PLATFORM)
to
EXEC_DIR=/media/ROOTFS
8.Do install everything in root file system
Insert SD card again
$ make install
9.Modify boot.cmd & boot.scr
Edit /media/BOOT/boot.cmd as below
mmc rescan 0
setenv bootargs 'console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw ip=off mem=60M davinci_enc_mngr.ch0_output=COMPONENT davinci_enc_mngr.ch0_mode=720P-60 davinci_display.cont2_bufsize=6291456 vpfe_capture.cont_bufoffset=6291456 vpfe_capture.cont_bufsize=6291456 video=davincifb:vid0=off:vid1=off:osd1=off dm365_imp.oper_mode=0 davinci_capture.device_type=4 vpfe_capture.interface=1 rootwait'
fatload mmc 0 80700000 uImage
bootm 80700000
Create boot.scr
$ cd /media/BOOT
$ mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Execute Boot Script' -d boot.cmd boot.scr
10.Umount SD card and insert to LeopardBoard DM368
Make sure the DIPSW is SD card boot.

Linux 3.0.0 rc1 released
Linux 終於在5月30日邁入新的重大版本 3.0
根據Linus的說法,這次的進版並沒有任何架構或API的重大變革,
而是Linus本人對於2.6.40以上的版本編號不認同以及2.X版本已歷經接近20年故有此進版動作.
回想Linux 2.2時代我才剛接觸Linux,
對Unix系統完全陌生還活在微軟帝國的勢力範圍,
而Linux 2.4時代進入職場開始真正使用並學習Linux.
時間過的真快啊,呵呵呵.
留一段 linux-omap 3.0.0-rc1 kernel build log 紀念這個重大的時刻.

根據Linus的說法,這次的進版並沒有任何架構或API的重大變革,
而是Linus本人對於2.6.40以上的版本編號不認同以及2.X版本已歷經接近20年故有此進版動作.
回想Linux 2.2時代我才剛接觸Linux,
對Unix系統完全陌生還活在微軟帝國的勢力範圍,
而Linux 2.4時代進入職場開始真正使用並學習Linux.
時間過的真快啊,呵呵呵.
留一段 linux-omap 3.0.0-rc1 kernel build log 紀念這個重大的時刻.

Beagleboard xM - Camera board LI-5M03
玩了一陣子LI-BCM3M1 camera board發現不管什麼解析度都只能達到5~8fps.數據相當的難看,主要原因是driver限制住了.
到chip vendor Aptina網站找mt9t112 datasheet 竟然還要簽 NDA,發信去也不鳥我...Shit.
因此轉而試試五百萬畫素的LI-5M03, Aptina 有提供datasheet

此外更提供給BeagleBoard XM driver source code放在github,我clone了一份.

mt9p031 driver我有做一些修改

Camera 測試的可用gstreamer.
不過實際測試frame rate還是無法到達30fps應該是gstreamer效率的關係,
因此我修改TI提供的demo程式來讀取camera確實就能達到30fps.

BeagleBoard Uart Level Shift
There are three Uart port can be use on BeagleBoard, while Uart 3 as default console port, Uart 1 & 2 are free to use. There are many devices can be connect to Uart, such as GPS module, blue tooth module and PWM controller.
But, there's a serious problem. The BeagleBoard I/O works at 1.8v and for most of devices 1.8v is not "High" enough. So, I'm trying to higher the 1.8v signal to 5v signal.
Google this issue, I found the procdure is called "Level Shift" and can be done with two n-channel FET. The actual electronic circuit as below.
http://www-g.eng.cam.ac.uk/mmg/teaching/linearcircuits/mosfet.html
The n-channel FET is 2N7000
http://www.fairchildsemi.com/ds/2N/2N7000.pdf
According to BeagleBoard SRM (System Reference Manual), Uart 2 pins can be found on the expansion header.
PIN 6 - UART2_TX
Make sure the pin mux is correct configured. It should be work.

BeagleBoard i2c SRF08
SRF08 is an ultra sonic range finder, I'm trying to connect it to BeagleBoard. The hardware interface is i2c and we need to do some modify to kernel & u-boot to get it work.
http://www.robot-electronics.co.uk/htm/srf08tech.shtml
Reference
http://yetanotherhackersblog.wordpress.com/2011/04/07/interfacing-the-beagleboard-with-an-srf08-ultrasonic-ranger-over-i2c/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+BeagleBoard+%28BeagleBoard.org%29&utm_content=FaceBook
1.Hardware interface
BeagleBoard i2c interface runs at 1.8v and SRF08 i2c interface runs at 5v. In order to get it work, we need i2c level shift. There are some chips can do it, what I got is PCA9517.
http://elinux.org/BeagleBoard_Hardware_Interfacing
http://ics.nxp.com/support/documents/interface/pdf/an97055.pdf
2.The circuit
We are planing to use BeagleBoard I2C2 interface, which pins are at expansion connector pin 23 and 24.
Be attention ! all the 10k resisters are rquired.
http://groups.google.com/group/beagleboard/browse_thread/thread/a6c42ef56c6a2da2/1608e6c0f0207a8d?lnk=raot
3.u-boot
First, make sure the pin mux is correct.
boards/ti/beagle/beagle.h
-MUX_VAL((CP(I2C2_SCL), (IEN | PTU | EN | M4) \
-MUX_VAL((CP(I2C2_SDA), (IEN | PTU | EN | M4) \
+MUX_VAL((CP(I2C2_SCL), (IEN | PTU | EN | M0) \
+MUX_VAL((CP(I2C2_SDA), (IEN | PTU | EN | M0) \
Then enable pull-up internal resister on i2c2
http://groups.google.com/group/beagleboard/browse_thread/thread/f5d308f24b27bb38/21febf1a98e0be0c?lnk=raot
4.kernel
Enable I2C2 interface
static int __init omap3_beagle_i2c_init(void)
{
omap_register_i2c_bus(1, 2600, beagle_i2c_boardinfo,

1.Hardware interface
BeagleBoard i2c interface runs at 1.8v and SRF08 i2c interface runs at 5v. In order to get it work, we need i2c level shift. There are some chips can do it, what I got is PCA9517.

2.The circuit
We are planing to use BeagleBoard I2C2 interface, which pins are at expansion connector pin 23 and 24.
Be attention ! all the 10k resisters are rquired.

3.u-boot
First, make sure the pin mux is correct.
boards/ti/beagle/beagle.h
-MUX_VAL((CP(I2C2_SCL), (IEN | PTU | EN | M4) \
-MUX_VAL((CP(I2C2_SDA), (IEN | PTU | EN | M4) \
+MUX_VAL((CP(I2C2_SCL), (IEN | PTU | EN | M0) \
+MUX_VAL((CP(I2C2_SDA), (IEN | PTU | EN | M0) \
Then enable pull-up internal resister on i2c2
http://groups.google.com/group/beagleboard/browse_thread/thread/f5d308f24b27bb38/21febf1a98e0be0c?lnk=raot

Beagleboard xM - Camera board
延續之前 DVSDK ,接著來看DSP Multimedia的應用
1.Beagleboard XM camera board
Leopard imaging inc 有一系列camera board支援BeagleBoard XM.
https://www.leopardimaging.com/Beagle_Board_xM_Camera.html\
有1.3M / 3M / 5M (百萬畫素) 鏡頭.其中 1.3M / 3M camera board 在 DVSDK 上已有driver.
我手邊有 LI-LBCM3M1 三百萬畫素 CMOS sensor mt9t111 (相容 mt9t112), DVSDK PSP linux已經包含mt9t112 driver.
載入camera driver需要修改bootloader 環境變數.
首先將SD card 連接至PC, 新增檔案BOOT/boot_dvi_lbcm3m1.cmd 如下
setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw ip=off mem=55M@0x80000000 mpurate=1000 omap_vout.vid1_static_vrfb_alloc=y omapfb.vram=0:8M mem=384M@0x88000000 omapfb.mode=dvi:hd720 omapdss.def_disp=dvi rootwait vram=8M camera=lbcm3m1'
fatload mmc 0 80200000 uImage
bootm 80200000
接著產生 boot_dvi_lbcm3m1.scr
gigijoe@gigijoe-laptop:/media/BOOT$ mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Execute Boot Script' -d boot_dvi_lbcm3m1.cmd boot_dvi_lbcm3m1.scr

Load Address: 0x00000000

增加camera=lbcm3m1,使相對應的driver會被自動載入.

2.Test camera board
首先先測試camera影像是否正常,最方便的方式是使用DVSDK built-in gstreamer
Camera device node 是 /dev/video0
gst-launch v4l2src always_copy=FALSE ! video/x-raw-yuv,width=640,height=480 ! queue max-size-buffers=8000 max-size-time=0 max-size-bytes=0 ! TIDmaiVideoSink videoStd=720P_60 videoOutput=AUTO numBufs=5
應該會在DVI output上看到影像
3.Play with camera board
現在來看實際上的應用,場景是將Camera board得到的影像透過DSP 壓縮成H.264格式,接著以RTP H.264封裝透過網路傳送到PC端,接著PC端將影像解壓縮並顯示在銀幕上

Beagleboard xM with TI DVSDK 4_01_00_09
Beagleboard xM 跟之前的 Beagleboard有相當多的差異,除了CPU / DSP 時脈的提昇,週邊也多了Ethernet, USB Hub 及 Camera interface.
不過 Nand flash 據說是因為成本的因素而拿掉了.因此Beagleboard xM只能經由 SD card boot.
TI DVSDK 提供很完整的多媒體展示,包含Media encode / decode, OpenGL 3D demo.
接下來將試著將Beagleboard xM DVSDK 安裝至 SD card.
1.參考DVSDK FAQ
http://processors.wiki.ti.com/index.php/DVSDK_4.x_FAQ#How_to_build_and_install_DVSDK_4.01_on_BeagleBoard-xM
根據DVSDK FAQ得知所需要的必要環境是 Ubuntu 10.04. Cross compile 為 CodeSourcery ARM 2009q1
2.Download DM3730 DVSDK 4.01 from TI
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/index_FDS.html
下載 dvsdk_dm3730-evm_4_01_00_09_setuplinux,大小約為1.5G.
下載時 TI 會要求帳號密碼,請自行註冊登入.注意帳號的Email 不能是yahoo之類的免費帳號.
下載完成後先變更檔案權限為可執行
$ chmod 755 dvsdk_dm3730-evm_4_01_00_09_setuplinux
執行安裝
$ ./dvsdk_dm3730-evm_4_01_00_09_setuplinux
3.Download patch script for DVSDK 4.01 to support BeagleBoard XM
http://processors.wiki.ti.com/images/5/5b/Setup-dvsdk-4-01-beaglexm-110126.zip
TI DVSDK並沒有支援Beagleboard xM,因此必須要做一些patch.
解開zip檔後會得到檔案 setup-dvsdk-4-01-beaglexm-110126.sh.
將它放在DVSDK root目錄,再依照以下內容修改 setup-dvsdk-4-01-beaglexm-110126.sh.

這個修改是為了可直接連上internet及修正 git am 所造成的 bug
4.變更權限並執行
$ chmod 755 setup-dvsdk-4-01-beaglexm-110126.sh
$ ./setup-dvsdk-4-01-beaglexm-110126.sh
這時這個script會自動去抓許多patch檔,並更新至DVSDK
5.編譯DVSDK
至DVSDK root目錄下
make clean
make all
6.安裝DVSDK 至 SD card
將SD card 連接至PC, 再來弄清楚device node為何 (用dmesg)
以我來說是 /dev/sdd
$ sudo bin/mksdboot.sh --device /dev/sdd --sdk ${PWD}

這個修改是為了可直接連上internet及修正 git am 所造成的 bug
4.變更權限並執行
$ chmod 755 setup-dvsdk-4-01-beaglexm-110126.sh
$ ./setup-dvsdk-4-01-beaglexm-110126.sh
這時這個script會自動去抓許多patch檔,並更新至DVSDK
5.編譯DVSDK
至DVSDK root目錄下
make clean
make all
6.安裝DVSDK 至 SD card
將SD card 連接至PC, 再來弄清楚device node為何 (用dmesg)
以我來說是 /dev/sdd
$ sudo bin/mksdboot.sh --device /dev/sdd --sdk ${PWD}

MySQL Setup
After compile & install MySQL there still something need to do.
In this case, MySQL install to /media/disk/usr/mysql
So, the $BASEDIR is /media/disk/usr/mysql
1.Create $BASEDIR/etc/my.cnf
# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
[client]
#password = your_password
port = 3306
socket = /tmp/mysqld.sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
user = mysql
port = 3306
socket = /tmp/mysqld.sock
datadir = /media/disk/usr/mysql/var
skip-external-locking
key_buffer_size = 16K
max_allowed_packet = 1M
table_open_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 128K

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (using the "enable-named-pipe" option) will render mysqld useless!
#
#skip-networking

# Uncomment the following if you want to log updates
#log-bin=mysql-bin

[mysqlhotcopy]
interactive-timeout
2.Create user mysql & group mysql
3.Change owner to user & group mysql
chown -R mysql:mysql /media/disk/usr/mysql/*
4.Install database
The datadir in my.cnf is the path to install database which is /media/disk/usr/mysql/var
Execute
# mysql_install_db --defaults-file=/media/disk/usr/mysql/etc/my.cnf --user=mysql
Installing MySQL system tables...

700101 0:34:10 [Warning] option 'myisam_max_extra_sort_file_size': unsigned value 2147483648 adjusted to 2147483647
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/media/disk/usr/mysql/bin/mysqladmin -u root password 'new-password'
/media/disk/usr/mysql/bin/mysqladmin -u root -h localhost password 'new-password'
Alternatively you can run:
/media/disk/usr/mysql/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /media/disk/usr/mysql ; /media/disk/usr/mysql/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /media/disk/usr/mysql/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /media/disk/usr/mysql/bin/mysqlbug script!
