USE DIFFERENT CROSS COMPILING TOOL CHAIN UNDER LTIB
---------------------------------------------
[4] [5]
[6] Why doesn't Sourcery G++ Lite Edition contain libraries for big-endian GNU/Linux? Or for systems with VFP or NEON?
Why does CodeSourcery provide GLIBC? Can I use the version that comes with my GNU/Linux distribution?
Why is the configuration name for GNU/Linux arm-none-linux-gnueabi instead of just arm-none-linux-eabi? Is there a GNU variant of the EABI?
Answer
The Free Software Foundation prefers that configuration names for GNU/Linux contain both the string linux and the string gnu. The configuration arm-none-linux-gnu refers to the legacy ARM ABI for GNU/Linux. Some tools depend on the fact that configuration names have at most three hyphens, so gnu and eabi were combined into a single word.
The ABI used on GNU/Linux is not a special GNU variant of the EABI; it is just the EABI.

BUILD FROM SCRATCH
------------------------------------------------
Note:
This will remove rootfs and all configrations.

Build all packages and kernel from scratch.
[root@localhost ltib-qs]#./ltib -m distclean
[root@localhost ltib-qs]#./ltib --config


ADD CUSTOMER BSP INTO LTIB MENU
--------------------------------
Steps to Add your new board into LTIB menu (CM-HS1)
01-MAR-2012
1. Add new machine ID for the new board:
Register a machine ID for the new board via http://www.arm.linux.org.uk/developer/machines/ website and then update mach-types.h under /linux_kernel_dir/arch/arm/tools/ to the latest version;

2. Add new board information into the LTIB menus:
a. Make a folder for the new Board Support Package (BSP) under '/ltib/config/platform/'. The folder name should be the same as that defined in main.lkc, i.e., '/ltib/config/platform/gsncomm'. Please refer to 2.c below.
b. Copy all files from an existing Board Support Package (BSP) folder to the new BSP folder. We use the one we did the evaluation, i.e., from 'phy3250';
c. Make necessary changes to main.lkc under new BSP folder '/ltib/config/platform/$NEW_BOARD/'. All contents in main.lkc that are related to CPU and board need to be modified.
d. Create a Linux kernel pre-configuration file, e.g., 'linux-2.6.34-gsncomm.config'. This file can be manually generated by running the LTIB, which has Linux Kernel configuration GUI. 'linux-2.6.34-gsncomm.config' is generated based on 'linux-2.6.34-phy3250.config' with some modifications to mach GridSense Lpc 3240 board. 'linux-2.6.34-gsncomm.config' has to be stored under path '/ltib/config/platform/$NEW_BOARD/'
e. Overwrite the Linux board configuration file 'defconfig' and 'defconfig.dev' under ''/ltib/config/platform/$NEW_BOARD/' with your own board configuration file, in which different Linux kernel pre-configuration file, and installed Linux packages can be defined. New Linux board configuration file can also be generated with the help of LTIB, which has a Linux board configuration GUI. Basically, board configuration file will decide what application will be installed in Linux Root File System (RFS).

3. Add new BSP into to Linux Kernel (here we use lpc32xx based board as example):
a. Add new board choice to Kconfig under '/linux_kernel_src_dir/arch/arm/mach_lpc32xx/'. Add sub menu items if required;
b. Add board level initialisation BSP source code under the folder. It is recommended the main source code file name follow the board name. i.e., BSP source code 'gsncomm.c' under '/linux_kernel_src_dir/arch/arm/mach_lpc32xx/'.
c. Add board level initialisation code file(s) to the Makefile within the folder.
d. Copy Linux kernel pre-configuration file 'linux-2.6.34-gsncomm.config' to folder '/linux_kernel_src_dir/arch/arm/configs/' and rename it to 'gsncomm_defconfig'.

4. Use LTIB menu-based GUI to do further configuration and then build the kernel. Fix any error raised during porting.




CHOOSE CUSTOMER BSP
-------------------------




UPDATE ALL PACKAGES AND PATCHES FROM CVS
---------------------------------------------
Just run"cvs update" in your ltib directory. It'll fetch the updates and in the ltib config you can see the 2.6.34 kernel support.



MISSING NODES UNDER /DEV/
--------------------------------------
Has to change default phytect 'busybox.config', and add support for 'mdev'.
then /rootfs/sbin/mdev will appear and symbol link to busybox.







Make /DEV/ nodes from device_table.txt
If the target architecture is different from the original one, a different cross compiler will be needed. It will be downloaded and installed in the correct location if it isn't already present.
How to add device nodes
Device nodes with static major/minor numbers can be added to the file ltib/bin/device_table.txt. The format is described in the file itself.

Since there is no dependency checking for device_table.txt, after adding a new entry, force rebuild devices to make sure the new /dev nodes are in the file system:

$ ./ltib -p dev -f


MISSING /PROC/DEVICES
-------------------------------
After changing the property of all files under 'etc/rc.d/init.d/', adding 'x' right, problem is solved.

HOW TO UNINSTALL LTIB
-----------------------------
[2] 在ubuntu系统上，假如ltib已经安装了，我们只需编译、重新配置ltib，
以非root用户登陆，进入ltib所在文件夹，依次输入以下两条命令：
./ltib clean
./ltib -c
即可先后配置linux应用软件包、linux内核。
编译成功后，~/ltib/rootfs/boot目录下，有新编译的内核文件uImage、设备树mpc8315erdb_default.dtb，分别拷贝到/tftpboot目录下。

MULTIPLE LTIB INSTALLATION
-----------------------------------
[1]Can I have more than one root file system on my host at the same time
Yes, the system will support multiple root file systems, for the same or for different target architectures.
If you are using an iso image, install your ltib archive into an different directory by entering a new directory name for the installation when prompted by the install script..
If you are using CVS, check-out CVS into a different directory by using the -d option to cvs co. For example:


ADD FILES TO THE TARGET ROOT FILE SYSTEM
------------------------------------------
[1] Can I add files to the target root file system without creating a package

Yes, to do this, you need to create a merge directory. There are 2 options:
1 Top level merge directory, that applies to all targets 2 Platform specific merge directory
The platform specific merge directory contents override the top level merge directory, which overrides the corresponding file(s) in your rootfs
Example:
You have a CVS version of LTIB, and you have build the tqm823l default configuration, now:
1 You want to add the a platform specific file /home/fred/myfile1 2 You want all platforms you may build to use your own /etc/hosts file
Here's what you would do:

$ cd
$ mkdir -p config/platform/tqm823l/merge/home/fred
$ cp /myfile1 config/platform/tqm823l/merge/home/fred
$ mkdir -p merge/etc
$ cp /hosts merge/etc
$ ./ltib

NOTES FROM LtibConvertPcsBsp
-----------------------------------------
-----+++ Deploying the BSP

The primary deployment mechanism in ltib is expected to be NFS. By
default ltib will build a root filesystem suitable for exporting as
a root filesystem in ~/ltib/rootfs . It is the user's responsibility
to export this directory and setup the bootloader parameters to
use this. Note that the built kernel can be located in ~/ltib/rootfs/boot


---++ Saving your work

Once you have booted your board and are happy to check in your work,
you need to do the following:

* copy the updated .config to defconfig
cp config/platform/mpc5200/.config config/platform/mpc5200/defconfig
* checking ltib changes to CVS
* copy new source files to the GPP

Machine ID Management.

[root@localhost ltib-qs]# service xinetd restart
#show whether tftp is running.
[root@localhost ltib-qs]# netstat -a | grep udp
[root@localhost ~]# chown q.yang /var/lib/tftpboot
[root@localhost ~]# chgrp users /var/lib/tftpboot
alternatively:
[root@localhost q.yang]# chown q.yang:developer /var/lib/tftpboot/
[root@localhost q.yang]# chmod g+w /var/lib/tftpboot/

#chmod 777 /var/lib/tftpboot


RESTART TFTP SERVER
---------------------
[root@localhost ltib-qs]# service xinetd restart


FAIL TO PUT FILE TO TFTP SERVER [4]

check the /etc/xinetd.d/tftp file..

change:
server_args = -s /tftpboot

NFS TROUBLE SHOOTING
-------------------------------------
Fail to connect NFS due to firewall
-----------------------------------
1. Upgrade system-config-firewall/system-config-firewall-tui rpm package so that
correct /etc/sysconfig/iptables, /etc/sysconfig/iptables-config can be generated.
2. Disable firewall.

UPGRADE FIREWALL RPM PACKAGE MANUALLY
----------------------------------------
The files modified and generated as a result of system-config-firewall (system-config-firewall-1.2.16-3.fc9.noarch.rpm)
[root@localhost eclipse]# ll /etc/sysconfig/ |grep ip

Packages that are needed when compiling Linux Kernel
-------------------------------------
With support for ppp_async, pppoe.


Maintaining a permanent connection to the net with pppd.

You can see why ppp failed from this log:
[root@GsnCommsModule user]# cat /var/log/messages


You can shut down the pppd connection by:
killall -HUP pppd


AUTO PPP
---------------------------
/svn/CableTracker/CommsModuleLinuxKernel/trunk/rootfs/etc/rc.d/rc.local
can automatically run all the shells that root user want to run after restart.


PPP account and connection retry
---------------------------------
/svn/CableTracker/CommsModuleLinuxKernel/trunk/rootfs/etc/ppp/peers/gsm

$cat gsm
lcp-echo-failure 0
/dev/ttyUSB3
115200
debug
defaultroute
usepeerdns

#ipcp-no-address
#ipcp-no-addresses
ipcp-max-failure 4
ipcp-accept-local
ipcp-accept-remote

# AUTHENTICATION
# If noauth works, use that, otherwise you have to pass
# the user name and password. This is an example of a
# standard Cingular user/pw combo

noauth
#ppp account infomation
user GridSense0002@maxwan.com.au
password GTre387a

crtscts
#persist will cause connection retry after ppp off-line
persist
maxfail 100
lock
connect '/sbin/chat -v -t6 -f /etc/ppp/peers/gsm_chat'

PULL DOWN ETH CONNECTION
----------------------------
[root@GsnCommsModule user]# ifconfig eth0 down

Decimal point in java script

[1] http://www.mredkj.com/javascript/nfbasic2.html

// Example: toFixed(2) when the number has no decimal places
// It will add trailing zeros
var num = 10;
var result = num.toFixed(2); // result will equal 10.00

// Example: toFixed(3) when the number has decimal places
// It will round to the thousandths place
num = 930.9805;
result = num.toFixed(3); // result will equal 930.981


PADDING '0'
-----------------------------------

function PadDigits(n, totalDigits)
{
n = n.toString();
var pd = '';
if (totalDigits > n.length)
{
for (i=0; i < (totalDigits-n.length); i++)
{
pd += '0';
}
}
return pd + n.toString();
}
