【Section1: Install Toolchain】
Install Blackfin Toolchain
Refer to the Note after this section if you meet some issueduring this installation.
1.1 Package Installation (recommended)
l? Get the latest Blackfin Toolchain from?ADI
l? Current up to date version is: 2011R1-RC4
l? Example download command:
> wget http://blackfin.uclinux.org/gf/download/frsrelease/531/9508/blackfin-toolchain-2011R1-RC4.i386.rpm
> wgethttp://blackfin.uclinux.org/gf/download/frsrelease/531/9512/blackfin-toolchain-elf-gcc-4.3-2011R1-RC4.i386.rpm
·??????????????????Check if a previous toolchain is already installed
·?????????????????If so, remove old tool chain using rpm -e ...
> rpm -qa blackfin-toolchain\*
·??????????????????Install Toolchain using RPM.
·?????????????????Note: If a previous toolchain is installed, you may need touninstall the previous toolchain see above
rpm-ivh blackfin-toolchain-*
More details on toolchain installation can be found atADI's?installation wiki entry.
1.2 Source Installation (advanced)
·??????????????????Prequisites
yuminstall automake autoconf ncurses-devel zlib-devel texinfo
·??????????????????set desired version
setVERSION=2011R1-RC2
·??????????????????Get the latest Version of the GNU toolchain
svncheckout svn://sources.blackfin.uclinux.org/toolchain/tags/$VERSION/
·??????????????????Compile and Install
>cd bfin_toolchain.$VERSION/buildscript/ > ./BuildToolChain -o<COMPILER_NSTALLATION_DIR>
Note:?這里要注意的是：
1.ADIoffers serious packages of toolchain of one version for different usages. Youshould select which one is needed.? I downloaded the 3 packages:
?> blackfin-toolchain-2012R2-RC1.i386.rpm
?> blackfin-toolchain-elf-gcc-4.3-2012R2-RC1.i386.rpm
?> blackfin-toolchain-uclibc-default-2012R2-RC1.i386.rpm
????? ??from the Blackfin Linuxwebsite in the toolchain file release page
?
2. Ubuntu does not support installing this toolchain by RPMtool.
? ??I used the "How to Install rpm package onUbuntu" approach to go around it. Chinese tutorial:
?????注意，用alien轉(zhuǎn)換的deb包并不能保證100%順利安裝，所以可以找到deb最好直接用deb
?????有時(shí)候，我們想要使用的軟件并沒(méi)有被包含到?Ubuntu?的倉(cāng)庫(kù)中，而程序本身也沒(méi)有提供讓?Ubuntu可以使用的?deb?包，你又不愿從源代碼編譯。但假如軟件提供有?rpm?包的話，我們也是可以在?Ubuntu中安裝的。
方法一：
1.?先安裝?alien?和?fakeroot?這兩個(gè)工具，其中前者可以將?rpm?包轉(zhuǎn)換為?deb?包。安裝命令為：?Intall the "alien"and "fakeroot" tools:
??????????????
$?sudo apt-get install alien fakeroot
2.?將需要安裝的?rpm?包下載備用，假設(shè)為?package.rpm。?Assume your package is:package.rpm
3.?使用?alien?將?rpm?包轉(zhuǎn)換為?deb?包：?use alien to convert rpmpackage into deb package:
$?fakeroot alien package.rpm
4.?一旦轉(zhuǎn)換成功，我們可以即刻使用以下指令來(lái)安裝：?After a while, if succeed, install it using command:
$ sudo dpkg -i package.deb
如何轉(zhuǎn)換rpm詳細(xì)教程，參考這里:?http://zhidao.baidu.com/question/377062512
[Section2. Install Eclipse]
Follow OS independent instructions:
Generally, follow instructions at:?link
Note: It seems that Blackfin Toolchain only works in HeliosEclipse
Install components:?
????? Blackfin ucLinux
????? GDB Hardware Debugging
????? Target Terminal Management
????? ZynxCDT
Below is my steps:
Refer to this web page:http://docs.blackfin.uclinux.org/doku.php?id=toolchain:eclipse:install
???2.1.Install the JavaRuntime Environment (JRE)
Checking your Java Runtime Environment version:?
$java -version
If you do not have Java installed, go through the :Install Java Runtime Env. 1.6.0?
After you finished, the lines below should be displayed:
$ java -version
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)
?
?2.2 Install the IDDE (Eclipse)
There are no executable installers for Eclipse. It isdistributed as a zip archive which you can unpack anywhere you like, and thenjust run the?eclipse.exe?program in the eclipse sub-directory.
To get the installer, visit?the?Eclipse download page.
You will be presented with a variety of download choices. Theonly difference between them is the default plug-in set. Since you will mostlikely be compiling/debugging code for the Blackfin processor, you shouldpick?Eclipse?IDE?for C/C++ Developers.:?
?Note: It seems that Blackfin Toolchain only works in?Helios Version?(Downloadthis verion)
Extract: eclipse-cpp-helios-SR2-linux-gtk.tar.gz ,?
???????1.Double-Clickon Archive and Extract Eclipse into /tmp
???????2.Open?Terminal?Window
???????3.Install RequiredPackages
?
$?sudo su
# apt-get install g++
?
?4.Relocate Eclipse
#?mv/tmp/eclipse /opt
?5.Create a Symlink
#?ln-s /opt/eclipse/eclipse /usr/bin/eclipse
6. After, you can Start Eclipse from Terminal simply with:
#?eclipse
or: (the way by which we launch Eclipse is under the Super Userpermision)
$exit
$ sudo eclipse
???????If you want toovercome the root permission issue, refer to:?here.?but it does not work on my Ubuntu.
?
???????Reference:?How-to Install Eclipse Juno4.2 C/C++ on Ubuntu
????????IfInstalled Eclipse on Linux, but it does not start,read this
????2.3 Install the?Blackfin Plug-ins
?The Blackfin plug-ins willrequire Eclipse 4.2, as well as the CDT. Additionally, you will have to installthe GDB Hardware Debugging CDT plug-in (it is usually not installed bydefault).?
??????????Toinstall the GDB Hardware Debugging plug-in, the CDT update site needsenabled.?
??????????Toenable the CDT site:
1.????????????????Select the Eclipse menu Window→Preferences.
2.????????????????Select Install/Update→Available SoftwareSites and select the site,?http://download.eclipse.org/tools/cdt/releases/juno.
(HereI used Helios, it's a little different. Keep it Enabled.?Maybe we need to add the link in the lastline)
3.????????????????Use the Enable button to enable the site.
?????Install the?GDB?Hardware?Debuggingplug-in via the?Update Manager:
1.????????????????Select the Eclipse menu Help→Install NewSoftware
2.????????????????Select the?http://download.eclipse.org/tools/cdt/releases/indigo?sitein the Work With list(Add this, if there isn't.)
3.????????????????Enable the?GDB?HardwareDebugging plugin under CDT Optional Features

TheBlackfin Debug plug-in results in extra selectable entries in the “DebugConfiguration” dialog, while the Tool chain plug-in allows for selecting thedesired tool chain out of a list from within the New Project Wizard dialog.
?
Install the Zylin CDT
TheEclipse C/C++ Development Tools (CDT) has excellent?GDB?support.However, there are a few stumbling blocks when trying to debug embeddedapplications, which?ZylinAS?has made some modifications in Eclipse CDT to improvesupport for?GDB?embedded debugging.
Pathfor update manager “Add Site”:?http://opensource.zylin.com/zylincdt
?? ? ? ?
?
?
Install Subclipse (SVN) ? (I skipped this)
Whilenot released with Eclipse, there is a Subversion plugin called?Subclipse. Visit the Subclipse homepage forsome?conciseinstall directions.
Onceyou have Subclipse installed, the interface is the same as usingthe?CVS?plugin.
?
Target Management Terminal
AnANSI (vt102) compatible Terminal including plug-ins for?Serial,?SSH?and?Telnet?connections.
To use a serial terminal in Eclipse Juno. (Here we use Helios)
?
1: Install the software for serial terminals:
Navigate to:?Help?->?Install New Software...
Dropdown list for?Work with:?tosay?Juno - http://download.eclipse.org/releases/juno
Select:?Mobile and Device Development,especially?Target Management Terminal?which is "An ANSI(vt102) compatible Terminal including plug-ins for Serial, SSH and Telnetconnections."

Section3.Library Installation
?
Checkout of common code
>svn co?https://nuforge.coe.neu.edu/svn/pal/tags/v1.1_gnu/0.1/bare-c
Edit Makefile.macros located in bare-c/common
Edit the prefix to the path where you want the library to beinstalled? For ex:?
> # --- Installationdirectories prefix = /home/student/agarwal/temp/pal
Edit the COMPILER macros to the path where you have installedthe compiler above
The defaultinstall path for all of our toolchains is?/opt/uClinux/
#-- Compiler COMPILER = ?<COMPILER_NSTALLATION_DIR>/bfin-elf/bin/bfin-elf-gcc
?
eg. #-- Compiler COMPILER= /opt/uClinux/bfin-elf/bin/bfin-elf-gcc
?
BackUP:
#-- Compiler
COMPILER = /ECEnet/Apps1/sce-ext-pkg/sw/bfin_toolchain.2011R1-BETA1/bfin-elf
For Compiling the library we need to source the blackfincompiler path .
For tcsh shell?
>?setenv PATH <COMPILER_NSTALLATION_DIR>/bfin-elf/bin/:$PATH?
For bash shell?
> export PATH;PATH=<COMPILER_NSTALLATION_DIR>/bfin-elf/bin:$PATH
? ? Here we use:
>export PATH; PATH = /opt/uClinux/bfin-elf/bin:$PATH?
Follow these steps to install the libraries
>cd common ?
> make clean?
> make?
> sudo make install
? Validate your environment???
>source <installation path>/bin/setup.sh?
?eg.> source /usr/uClinux/bfin-elf/bin/setup.sh
>cd demo?
> make clean?
> make
??????? This make shouldcomplete without error. (But we meet several errors)
? ==============================================
Here, I just referred some other instructions, and:
?1.deleted Eclipse,?
?2.Downloaded the Eclipse(Juno)
?3.Set the PATH
?
1. ReInstall the Eclipse
? ? ? go to the "eclipse" folder:
>cd /opt
>rm -rf eclipse
2. Download the Eclipse (Juno)
?
? ??Select the Juno version,?Download the eclipsepackage from:?Linux 32bit
? ? ? ?
? ? ? ?Extra it into/home/yourname/programfiles/
?
? ? ? ?We have Installed the Java RuntimeEnvironment above, so we don't need to install it here.
?
3. Configure the?environment variable(PATH)
?
? ? ??Modify the environment variable of "bfin-linux-uclibc-gcc"
? ? ? ? In Terminal, run:
>sudo gedit /etc/profile
?? ? ??Modify the EnvironmentalVariable. Note, this is user environmental variable, After this we can only use
"bfin-linux-uclibc-gcc" but cannot use"sudo?bfin-linux-uclibc-gcc". All the command after"sudo" is for using?
system environmental variable but not user's environmentalvariable.
? ? ? ?In the gedit window add the linebelow at the tail.
?>export PATH=$PATH:/opt/uClinux/bfin-linux-uclibc/bin?
? ??And for the JRE PATH configure, add the line below:
?>JAVA_HOME=/opt/java/32/jre1.6.0_16
?> PATH=$JAVA_HOME/bin:$PATH
?? ? ?See the snap below:
? ??
?
4. Building a uClinux Hello World project?
?? ? ? ?Go to the location ofeclipse:"/home/yourname/programfiles/eclipse", Run the eclipse by:
>cd?/home/yourname/programfiles/eclipse
> ./eclipse?
? ? ? ? ? In Eclipse,New->Project->C/C++ -> C Project -> "Project type:Executable/Empty Project" and?
"ToolChains:Cross GCC " -> "Next" ->Set the path of your "bfin-linux-uclibc-gcc" ?-> finish.
See the snap:
? ? ? ?
? ? ? ?And build your Hello Worldproject:

================= Connect with Target Board =================
? ? ? ? In this Section, we are going todownload the executable bin file made by Eclipse down to target.
? ? ? ? 1. Install the minicom
? ? ? ? 2. Install the USB-UART bridgeconverter driver on Linux
? ? ? ? 3. Install the USB-Ethernet bridgeconverter driver on Linux, and Configure it.
? ? ? ? 4. Test the Communication functions.
? ? ? ? 5. Test the J-TAG connection if Ihave interests.
?
???1. Install the minicom
? ? ? ? ?In the Terminal, input:
>sudo apt-get install minicom
? ??2. Install the USB-UART bridge converter driver on Linux
? ? ? ?Install driver for USB-UART bridge converter on Linux Ubuntu12.04
? ? ???Ubuntu下USB轉(zhuǎn)串口芯片驅(qū)動(dòng)程序安裝，支持cp210x,pl2303等
?
? ? ???Reference:?Fixing the cp210x open - Unable toenable UART Error
?
? ? ???When you plugin your USB-UART converter, and run "> ls /dev/tty*", if you don'tsee the
?/dev/ttyUSB0 (or similar), your Linux does not detect your USB-UARTdevice.
?
We need to install the driverfor your device.
?
Here we use Ubuntu12.04, andUpdated the source to 3.2.0 version. If there is difference about?
version Number from your OS platform, please try to modify it into yours.
?
?
1.Download the Linux Source Code
?
Open a terminal and executethe following commands. Note that your version of Linux may differ?
slightly -- adjust accordingly.
$cd ~
$sudo apt-get install build-essential linux-source
$cp /usr/src/linux-source-3.2.0.tar.bz2 .
$bunzip2 linux-source-3.2.0.tar.bz2?
$tar xf linux-source-3.2.0.tar?
$cd ~/linux-source-3.2.0
?
?
?
2.Recompile and Reinstall the cp210x Driver
?
From within a terminal,execute:
$cd ~/linux-source-3.2.0
$make oldconfig
$make prepare
$make scripts
$cp /usr/src/linux-headers-3.2.0-34-generic-pae/Module.symvers .
?
Here, I have the"3.2.0-29" version also, I launched the command above, but not thebelow:
?"cp /usr/src/linux-headers-3.2.0-29-generic-pae/Module.symvers ."
?
Recompile and Reinstall thecp210x Driver
Here, We can actually installmany kinds of USB-UART converter drivers. We take cp210x as the
?example.
From within a terminal,execute:
?
$make M=drivers/usb/serial
$sudo mv /lib/modules/$(uname -r)/kernel/drivers/usb/serial/cp210x.ko/lib/modules
? /$(uname -r)/kernel/drivers/usb/serial/cp210x.ko.old
$sudo cp drivers/usb/serial/cp210x.ko /lib/modules/$(uname-r)/kernel/drivers/usb
? /serial/
$sudo modprobe -r cp210x
$sudo modprobe cp210x
?
Reboot Linux system.
?
Run Terminal:?
$ls /dev/tty*
The we can see the device isdetected by Linux Host OS:
?
? ? ?Reference:?http://pharos.ece.utexas.edu/wiki/index.php/Fixing_the_cp210x_open_-_Unable_to_enable_UART_Error_-_04/17/2011
?
? ? Then, We can configure the minicom to communicatewith our target board.
?
?
======================================================
Here is an example ofconfigure the parameters of minicom for TLL6527M PAL board:
I just copied it here hardlywithout any font editing. Sorry about that.
Serial Communications from Host-PC to TLL6527M Target Hardware
TheTLL System Design Environment (SDE) running on the host PC comes pre-configuredwith
?the required settings for serial-UART communications between the host PCand the TLL6527M
?base module. Generally, for use with TLL6527M the settings need not to bechanged?
(Note: From the SDE OS version 0.3.2, the serial terminal program Minicom isset to?
open /dev/ttyUSB0 with the needed configuration as mentioned above.).
Tostart serial communication from host to the TLL6527M, open the serialcommunication terminal?
program Minicom. Just open a terminal window on your Linux SDE running on thehost PC? and?
type the command "minicom" at the command prompt on your host PCterminal console.
TheTLL6527M on power-up? is set by default to the following serial-UARTcommunication settings:
Bitsper second = 115200
Databits = 8
Parity= None
StopBits = 1
Flowcontrol = None
?Makesure that the TLL6527M's USB-UART port has been mapped to a ttyUSBx device nodein the /dev?
folder on the host PC SDE. See following example:
?
Nowmake sure that this "ttyUSBx" is set as the destination port, baudrate is 115200,
?and 8N1 mode for minicom, by running the command 'minicom -s'. Note thatrunning the?
"minicom -s" command as a normal user will only apply the settingsfor the current?
session. In order to make the settings permanent, these commands need to be runwith?
root privileges.See example below:?
Thefollowing window will appear on your host PC terminal window:?
Goto ‘Serial port setup’, following screen will appear, make sure that serialdevice is set to ‘/dev/ttyUSB0’?
and bps/par/bits is set to 115200 8N1:
?
Nowgo back to the main menu and choose ‘save setup as dfl’. This will save theconfiguration settings and from next time?
onwards user can directly run ‘minicom’ command without the option ‘–s’ and itwill load settings from the saved file.
RESETthe target by using the SDE's TLL6527M reset utility or by pressing the RESETbutton on the target.?
Followingmessages will be displayed on the terminal. By default, U-Boot is setupto?
automatically start booting the OS after waiting for a few seconds for the userto?
interrupt the automatic launch by pressing any key. So to stop U-Boot fromloading?
uClinux and provide U-Boot command prompt, just hit any key. (This is assumingTLL6527M?
is flashed with u-boot and uClinux. TLL6527Ms are pre-flashed with firmwarebefore shipping).
?
?
?
?
?
? ? ? ? ?Go to the website of yourconverter applier, for me:?Here, Download?
? ? ? ? ?I halted here. :( But I nevergive up, solved it next:)
?? ? ? ? Here is another simpler way to install thedriver:?

?
? ??3. Minicom configuration:
?? ?See:?http://blog.sina.com.cn/s/blog_55a4cddc0101afs8.html
??To here, we canuse Eclipse to develop our own Blackfin-uClinux app and send it down to ourtarget
?? ? board (TLL6527M PAL Board), But there is still no our desiredToolChain?outof a list from within the New Project Wizard dialog
?? ??
?
==========?Add the?Blackfin Linux FDPIC GNU Toolchain(bfin-linux-uclibc)?==========
? ? ? ??Then I installed the Blackfin Plug-ins againfor Juno
? ? ? ??Reference :?Installing Eclipse 4.2 (Juno)
? ? ? ??There contains:
?? ? ??? ? ? ??`. A Java Runtime Environment (JRE) version1.6 or newer
?? ? ??? ? ? ??`. Eclipse IDDE (version 4.2 recommended)
?? ? ??? ? ? ??`. C/C++ Development Tools (CDT)
?? ? ??? ? ? ??`. Blackfin toolchain
?? ? ??? ? ? ??`. Blackfin Plug-ins
?
? ? ? ??Here we only installed thePlug-ins:
? ? ? ??The Blackfin plug-ins willrequire Eclipse 4.2, as well as the CDT.?
? ? ? ??Additionally, you will have toinstall the GDB Hardware Debugging?
? ? ? ??CDT plug-in (it is usually notinstalled by default). To install?
? ? ? ??the GDB Hardware Debuggingplug-in the CDT update site needs enabled.
?
? ? ? ??--------
?? ? ? ?To enable the CDT site:
? ? ? ??1. Select the Eclipse menuWindow→Preferences.
? ? ? ??2. Select Install/Update→Available SoftwareSites and select the site,?
? ? ? ??3.http://download.eclipse.org/tools/cdt/releases/juno.

? ? ? ??The?Tool chain plug-in?allows?for selecting the desired tool chain out of alist from within the?
? ? ? ??New Project Wizard dialog.
? ? ? ??
? ? ? ??As the dialoge box said, restart Eclipse.
?
? ? ? ??---------
? ? ? ??Then when we creat a C Project, "Projecttype":Empty Project, in the "ToolChains" box,?
? ? ? ??there appears:"Blackfin Linux FDPIC GNUToolchain(bfin-linux-uclibc)"
? ? ? ??See the Snap pic below:

======================================
=========== Ethernet Connection ==========
?
? ? Here, I'm going to configure the Ethernet manually.
?
? ? ? ? I tried to run palTelnet.sh, butfailed by some errors.:
-----------
./palTelnet.sh: 44: read: arg count

Manually Setting IP Address
Thissection shows what happens inside the script described in section 2 and allowyou to follow the
setup?manually.
1. Identify the Ethernet Interface Name inside the VirtualMachine
Each timethe Ethernet adapter is connected a different name may be associated with it.To list
the currentlyknown Ethernet interfaces, open a new terminal, and execute
>ifconfig
Ifconfig will list two connections.?
?? ?A) Interface with IP address (this is the connection to theinternet), Example output:
eth0Link encap:Ethernet HWaddr 00:0C:29:51:9B:E6?
inet addr:192.168.64.138?Bcast:192.168.64.255 Mask:255.255.255.0?
inet6 addr: fe80::20c:29ff:fe51:9be6/64 Scope:Link?
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
B) Interface without IP address (connection to PAL)
The device #: 00:50:B6:xx:xx:xx is your Ethernet Adapter #
eth1Link encap:Ethernet?HWaddr 00:50:B6:0A:2A:1A?
inet6 addr: fe80::20c:29ff:fe51:9be7/64Scope:Link?
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
? ? ? ? ?The PAL interface can berecognized by?
?
? ? ? ? ?(1) a different second line: the line startingwith "inet addr" is missing?(even though the "inet6addr" may be listed)
? ? ? ???(2)the HWaddr starts with 00:50:B6.
2. Set IP address for interface connected to PAL
Assign IP address by using the following command?
(weassume?eth1?is the Ethernet connection without specified IPaddress)
>sudo ifconfig?eth1?192.168.40.1
"sudo" allows executing a command as root(administrator). ?For VM pal user, PW:real happy?
3. Validate that the interface has accepted the IP setting
Use "ifconfig" again
4. Establish a Telnet connection to the board.
Each PAL is set by default to the IP 192.168.40.211 (you can use"ifconfig" through minicom to get it)
Open a telnet session by
>telnet 192.168.40.211
For my target PAL board, Username: root, PW:uClinux
I Set it succesfully, So the Ethernet connection is configuredcorrectly. That means our driver installation is?Done!
?
?
========== ?Configure your telnet connection with thetarget board ? =======
Sometimes, when our automatically network connection is notstable, i.e. the DHCP can not work proplerly,
?we need the mannually conifigure the ip for our telnet.
Manually Configuring Ethernet
This section describes how to manually configure the Ethernet connectionon SDE 5.3.x. This is an?
alternative to?running the automated setup script add-trendnet-adapter.py.
1. Connect TU2-ET100and make sure it is connected to the Virtual Machine (see instructions?here)
2. Open context menu toto configure connections through NetworkManager.
Click right mouse button on NetworkManager icon
Select "Edit Connections ..."
3. In the dialog box"Network Connections", select the Wired Connection that correspondsto your USB
Ethernet adapter.
Note which connection has appeared after plugging in the USBEthernet adapter. The image below,?
assumes??"eth0" is the connection for the TU2-ET100.
Then, select "Edit ..."
4. Validate that theTU2-ET100 was correctly selected
The Device MAC address should start with 00:50:b6.
5. Select Tab"IPV4 Settings", and configure the interface.
Under?Method,?select "Manual"
Select:?Add
Enter the following values into line under Addresses
Address: 192.168.40.1
Netmask: 255.255.255.0
Gateway: 192.168.40.1
Close "Editing eth0" dialog box by selecting"Save"
Save button is grayed out unless valid values are entered forAddress.
6. Close dialog boxNetwork Connections.
The Ethernet connection is now configured. The sameconfiguration will be recovered next time
the same USB Ethernet adapter is connected.

?===============================================
If you want to use the library "libasound.a/out",?
you may need the "libasound2" package.
?* For My Nuggets:
?* I need library "TLL6527M_C_API_uClinux_TLL2012R1DevTEST" from /prerelease20120823/libary/elfStatic/
?* I need include /prerelease2012xxxx/inclue/common/
?*
?* For Audio:
?* I need library ?"asound" from /opt/ALSA_LIB
?* I need include .../prerelease2012xxxx/inclue/audio/
?* I need include ?/opt/ALSA_INCLUDE/alsa/sound
? ? I found there is no /opt/ALSA_LIB folder in my Ubuntu12.04 system disk.

----------------------
At this moment we're only supporting our Fedora based TLL SDE as Design / Development host OS for TLL platforms, this enables us to ensure all the tools/settings/dependencies work seamlessly with each other and thus requires us to concentrate efforts on a single platform avoiding a proliferation of different OS flavors. Hence we've tested the nuggets and build tools ONLY on TLL SDE(Fedora).
I would guess that ALSA libs would not be OS flavor dependent and might be usable just by coping library binaries and include header files over to your Ubuntu machine. However we'll not be able to support any issues you might face there.
Why don't you consider building a personal TLL SDE bootable pen drive which you can plug into your own machine while working with TLL platforms and then just reboot your system into your ubuntu when you need to use other things you are using. You can install it on a 4GB (or greater) pen drive.
Here is a link to SDE installation notes:
https://tll.assembla.com/spaces/designcenter/wiki/System_Design_Environment#2._installation_of_tll_sde
Please feel free to let us know any issues you face with this use mode of SDE.
?---------
Hello ,
let me echo his words.
I would not recommend any use on a custom installation. There are too many variables that can not be sufficiently controlled. As such it is practically infeasible to support such an installation.
Alternatively, you can install/run the SDE directly as outlined by Ashish, however at a loss of company-specific customizations.

? ? ----------------------------
至此，我配置好了blackfin的開(kāi)發(fā)環(huán)境，但是沒(méi)法配置適用于TLL所有板載功能的開(kāi)發(fā)環(huán)境。因?yàn)門LL板自己的開(kāi)發(fā)環(huán)境為了使用TLL板，有太多的東西需要配置。我并沒(méi)有完整的配置文檔。或許他們公司經(jīng)過(guò)一次次的修改，才發(fā)布的SDE本身已經(jīng)不知道要配置哪些東西了。
到此為止吧。。。。。但是：
=============================================================================
? ??
? ? But when I compile the accelerometer, there is no errors happened. This makes me burn a new fire in my mind.
? ? I began to test the other nuggets except audio.
=============================================================================
? ??? ? OMG!!!
? ? I fixed this problem by: add the libarary -ldl into my objects.mk file which is created by Eclipse.
? ? so:

=====================================================
遇到 Eclipse 編譯時(shí)出現(xiàn)：
undefined reference to '_dlclose'
undefined reference to '_dlopen'
undefined reference to '_dlsym'

我的解決辦法：
? ? 我是修改了.mk 文件，實(shí)際上是增加了一個(gè)庫(kù)， dl (dynamic link)?
? ? 在原本描述鏈接庫(kù)的地方: LIBS := -lTLL6527M_C_API_uClinux_TLL2012R1DevTEST -lasound? ? 修改為:"LIBS := -lTLL6527M_C_API_uClinux_TLL2012R1DevTEST -lasound -ldl再重新編譯，就沒(méi)有錯(cuò)誤產(chǎn)生了。
