Ubuntu配置上位机Blackfin开发环境手记：

[参考]http://blog.csdn.net/cp1300/article/details/8205282

 

【Section 0: Working Aim 工作目的】

现在手里有一个嵌入式开发板，搭载的是 AnalogDevices 公司的 Blackfin527 Processor，预装板载Uclinux操作系统。现在要配置上位机Linux/Ubuntu12.04 的开发环境，包括BlackfinToolchain，Eclipse开发环境，和Library.

 

【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: 这里要注意的是：

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转换的deb包并不能保证100%顺利安装，所以可以找到deb最好直接用deb

     有时候，我们想要使用的软件并没有被包含到 Ubuntu 的仓库中，而程序本身也没有提供让 Ubuntu可以使用的 deb 包，你又不愿从源代码编译。但假如软件提供有 rpm 包的话，我们也是可以在 Ubuntu中安装的。

方法一：

1. 先安装 alien 和 fakeroot 这两个工具，其中前者可以将 rpm 包转换为 deb 包。安装命令为： Intall the "alien"and "fakeroot" tools:
              

$ sudo apt-get install alien fakeroot

2. 将需要安装的 rpm 包下载备用，假设为 package.rpm。 Assume your package is:package.rpm

3. 使用 alien 将 rpm 包转换为 deb 包： use alien to convert rpmpackage into deb package:

$ fakeroot alien package.rpm

4. 一旦转换成功，我们可以即刻使用以下指令来安装： After a while, if succeed, install it using command:

$ sudo dpkg -i package.deb

如何转换rpm详细教程，参考这里: 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

 

 

 

The Blackfin plug-ins can be obtained from the http://blackfin.uclinux.org/eclipse/ site via the Update Manager:

             1.Select Help→Install New Softwarefrom the Eclipse menu
             2.Click the Add button
             3.Add http://blackfin.uclinux.org/eclipse/ as anew site"Blackfin GNU"

Thenyou can select the plug-ins to install:

     

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."

Click Next and anything else to finishthe install ...

2: Open the view

Navigate to: Window -> Show View -> Other ... -> Terminal -> Terminal (NOTE:singular Terminal, not plural Terminals)

3: Open a terminal

The rest should be fairly obvious as the view contains icons toConnect, Disconnect, Settings, etc which are related to Serial, SSH and Telnetconnections.

Reference: click here

 

TargetManagement Terminal Serial Connector requires RXTX

Installationas an Eclipse Plugin via Update Manager:

InEclipse, choose Help > Software Updates…

AddNew Remote Site:

Name = RXTX URL =http://rxtx.qbang.org/eclipse/

          · select proper version, InstallAll

 

Untill Now, we have installed the components:  

BlackfinucLinux (Blackfin plug-ins)

GDB Hardware Debugging

Target Terminal Management

ZynxCDT (We installed ZylinCDT instead)

 

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:

       

 

        This method is only for building theuClinux app. If you want to build Bare-Metal

================= 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转串口芯片驱动程序安装，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: 
 http://blog.sina.com.cn/s/blog_55a4cddc0101afs8.html

 

    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.

        4. Use the Enable button to enable the site.

 

        ---------

        Install the GDB Hardware Debugging plug-invia the Update Manager:

        1. Select the Eclipse menu Help→Install NewSoftware

        2. Select thehttp://download.eclipse.org/tools/cdt/releases/indigo site in the Work Withlist

        3. Enable the GDB Hardware Debugging pluginunder CDT Optional Features

 

        ---------

        The Blackfin plug-ins can be obtained fromthe 

        http://blackfin.uclinux.org/eclipse/    site via theUpdate Manager:

 

        1. Select Help→Install New Software from theEclipse menu

        2. Click the Add button

        3. Add http://blackfin.uclinux.org/eclipse/as a new site "Blackfin GNU"

 

        ---------

        Then you can select the plug-ins to install:

        The Blackfin Debug plug-in resultsin extra selectable entries in the “Debug Configuration” dialog, 

        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

WARNING: TRENDnet TU2-ET100 not found.

  1) Validate USB connection from TU2-ET100 to host.

  2) Validate TU2-ET100 is connected to virtual machineinstead of host).

     check: Virtual Machine -> RemovableDevices -> asix ax88772

Press <ENTER> to continue, <CTRL>-C to stop

./palTelnet.sh: 44: read: arg count

-----------

        Itsays the TRENDnet TU2-ET100, I thought it was because of the driver ofTU2-ET100 was not configured.

        (The gray part does not work, youcan just skip it)

        Download the driver from:

       http://www.trendnet.com/downloads/list_subcategory.asp?SUBTYPE_ID=1003

        Extract it into:

       /home/sonictl/Downloads/LINUX2.6.9_REV122/AX88772_772A_LINUX2.6.9_REV122/

open readme, it says:"This driver is only for Kernel 2.6.9to 2.6.13"

It seems like I need to download the Kernel2.6.9. get it 

        from:get"linux-2.6.9.tar.bz2" from: www.kernel.org/pub/linux/kernel/v2.6/

 

        Open a terminal and execute thefollowing commands.

        

        > $ cd ~

        > $ sudo mv~/Downloads/linux-2.6.9.tar.bz2 /usr/src/

        > $ cp/usr/src/linux-2.6.9.tar.bz2 .

        > $ bunzip2 linux-2.6.9.tar.bz2

        > $ tar xf linux-2.6.9.tar 

        > $ cd ~/linux-2.6.9

        

        Recompile and Reinstall the cp210xDriver,From within a terminal, execute:

        > $ cd ~/linux-2.6.9

        > $ make oldconfig

I pressed all Return Key.

        > $ make prepare

        > $ make scripts

        > $ cp/usr/src/linux-headers-3.2.0-34-generic-pae/Module.symvers .

        

To here I get halted. I searched online for a while, and Did thefollowing:

========================================================

 

        Retry Install the ASIX AX88772Driver for Linux

        

        Download the driver for Kernel3.x （my kernel is 3.2.0, you can update your kernel by 

> sudoapt-get install build-essential linux-source 

 unzip the Package_YouDownloaded.zip

 go into the folder, and open the readme file in gedit

$sudo su

# make

        If the compilation is well, the asix.ko will be created under the current

        directory.

        If you want to use modprobecommand to mount the driver, executing the

    following command to install the driver into your Linux:

# [root@localhosttemplate]# make install

        

     ----------------

     Usage:

     ----------------

 

     1. If you want to load the drivermanually, go to the driver directory and

        execute the following commands:( this does not work, skip )

 

[root@localhosttemplate]# insmod asix.ko

 

     2. If you had installed the driverduring driver compilation, then you can use

        the following command to loadthe driver automatically. (I used this one)

 

[root@localhostanywhere]# modprobe asix

 

     Ifyou want to unload the driver, just executing the followingcommand:

 

[root@localhostanywhere]# rmmod asix

     ----------------

        Test if the driver is loaded:

        But How?

 

==================================

        So, Ibegan to configure the Host Manually.

 

       First, check the USB devices connected on Ubuntu Linux:

         >lsusb

       we get:

-----------

       $ lsusb

       Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 roothub

       Bus 001 Device 002: ID 80ee:0021 VirtualBox USB Tablet

       Bus 001 Device 006: ID 10c4:ea60 Cygnal IntegratedProducts, Inc. CP210x Composite Device

       Bus 001 Device 007: ID 0b95:7720 ASIX Electronics Corp.AX88772

 

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.

    And I received the notes form the TLL board provider:
----------------------
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的开发环境，但是没法配置适用于TLL所有板载功能的开发环境。因为TLL板自己的开发环境为了使用TLL板，有太多的东西需要配置。我并没有完整的配置文档。或许他们公司经过一次次的修改，才发布的SDE本身已经不知道要配置哪些东西了。

到此为止吧。。。。。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:

   /* For My Nuggets On Ubuntu12.04:
    * You need library  "TLL6527M_C_API_uClinux_TLL2012R1DevTEST" at /prerelease20120823/libary/elfStatic/
    * You need include  /prerelease2012xxxx/inclue/common/
    *
    * For Audio:
    * You need library  "dl" (No need to assign its path, system default.)
    * You need library  "asound" from /opt/ALSA_LIB
    * You need include  .../prerelease2012xxxx/inclue/audio/
    * You need include  /opt/ALSA_INCLUDE/alsa/sound
    */

    
=====================================================
遇到 Eclipse 编译时出现：
undefined reference to '_dlclose'
undefined reference to '_dlopen'
undefined reference to '_dlsym'
undefined reference to '_dlsym'
我的解决办法：
    我是修改了.mk 文件，实际上是增加了一个库， dl (dynamic link) 
    在原本描述链接库的地方:

LIBS := -lTLL6527M_C_API_uClinux_TLL2012R1DevTEST -lasound

    修改为:"

LIBS := -lTLL6527M_C_API_uClinux_TLL2012R1DevTEST -lasound -ldl

再重新编译，就没有错误产生了。

=====================================================    

    But I still met the errors sent from board when I was launching the audio app on the board:
