Project: How to setup the mini2440 dev tools

It took me a little while to get the 'out of the box' tooling up and running for the mini2440 (3.5") so I'm putting the steps here. To get your own 2440, try here.

These instructions are for the no-frills sofware that comes with the mini2440. Nothing fancy, just the default Qtopia 2.2.0 on 2.6.29.

Host Linux (Ubuntu 9.10 - 32bit)
I can't stand Red Hat so I couldn't bring myself to use the arm9.net RH9 iso for the host pc.  Instead, I shot myself in the foot by using a 64bit version of Ubuntu 9.10. This was more trouble than it's worth and ultimately I couldn't resolve all the 64/32bit library issues, so I installed a vmware image of 32bit Ubuntu 9.10.

Dependencies
With a brand new 9.10 install, run the updater and then get these additional packages.
sudo apt-get install g++ libx11-dev libxmu-dev libxext-dev zlib1g-dev libjpeg62-dev libssl-dev uuid-dev

The arm-linux-gcc-4.3.2 toolchain
The following is based on the instructions found in this very handy manual PDF (English) with some minor changes for Ubuntu.

We'll need these archives from the DVD or website
arm-linux-gcc-4.3.2.tgz  examples.tgz

Extract the contents
chmod +x *.tgz
sudo tar xfzv arm-linux-gcc-4.3.2.tgz -C /

Add the bins to your path
sudo gedit /etc/bash.bashrc  (and add this line: PATH=$PATH:/usr/local/arm/4.3.2/bin )

reload your profile and see if they are found
arm-linux-gcc -v

If all went well, you should see this:
    Using built-in specs.
    Target: arm-none-linux-gnueabi
    Configured with: ....[config details]
    Thread model: posix
    gcc version 4.3.2 (Sourcery G++ Lite 2008q3-72)

Install the examples 
Note: the "opt/FriendlyARM/mini2440" path name is hard-coded into the build scripts so unless you want to adjust them, you should use this convention (case sensitive)
sudo mkdir /opt/FriendlyARM
sudo mkdir /opt/FriendlyARM/mini2440
sudo tar xfz examples.tgz -C /opt/FriendlyARM/mini2440/
sudo chown -R [yourgroup]:[youruser] /opt/FriendlyARM

now verify the tooling by compiling one of the examples:
cd /opt/FriendlyARM/mini2440/examples/hello/
make

You should see:
arm-linux-gcc -o hello hello.c

and the binary appears as well:
ubuntu:/opt/FriendlyARM/mini2440/examples/hello$ ls -l
-rwxr-xr-x 1 user:user 5061 2010-02-01 01:30 hello
-rw-r--r-- 1  user:user   73 2006-08-25 13:48 hello.c
-rw-r--r-- 1  user:user   98 2004-10-09 14:23 Makefile

check the executable:
file hello
hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.14, not stripped

Follow the instructions in the PDF above for moving the file to the 2440 and running it.

These examples demonstrate some of the hardware bits that are available on the 2440.  They dont use qt though, so if you want to build an app with a gui, then you'll need to read on...

Installing x86-qtopia
x86-qtopia provides tools and support for developing qt applications and running them on the host pc in a simulated embedded environment.  Here's how to set it up.

Extract the archive to: /opt/FriendlyARM/mini2440/
sudo tar xfvz  x86-qtopia.tar.gz  -C /opt/FriendlyARM/mini2440

Extract the individual archives:
cd /opt/FriendlyARM/mini2440/x86-qtopia/
sudo chmod +x *.gz
sudo tar xfz qtopia-2.2.0.tar.gz
sudo tar xfz konq.tar.gz
mkdir qtopia-2.2.0-FriendlyARM/qtopia/image
sudo tar xfvz fonts.tar.gz -C qtopia-2.2.0-FriendlyARM/qtopia/image

Some of the source code needs to be adjusted slightly in order to compile. Big thanks for the help here and here (skip2816)

Edit the four files below as noted:
sudo gedit  /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/libraries/qtopia/qmemoryfile_unix.cpp
line 141:  --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
line 141:  +++ f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

sudo gedit /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qt2/src/tools/qmemoryfile_unix.cpp
line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

sudo gedit /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/libraries/qtopia/backend/vobject.cpp
line 419: --- char *dot = strrchr(g,'.');
line 419: +++ char *dot = (char *) strrchr(g,'.');

sudo gedit /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/plugins/codecs/wavplugin/wavplugin.cpp
line 435: char *ext = strrchr( path.latin1(), '.' );
line 435: char *ext = (char *) strrchr( path.latin1(), '.' );

Grab ownership or else the install will fail...
sudo chown -R [youruser]:[yourgroup] /opt/FriendlyARM/

I edited the build scripts to remove the initial archive removal and extractions.  This will prevent the source code changes above from being deleted and overwritten (which the scripts will do).  Alternatively, you can simply run the configure statement by hand, then run make, make install, etc..

UPDATE: I've posted the build scripts I've used here.

Finally you can run the build...
./build-all

That should do it.

Installing arm-qtopia
Extract the archive to /opt/FriendlyARM/mini2440/
sudo tar xfz arm-qtopia.tgz -C /opt/FriendlyARM/mini2440/

Edit the build scripts to remove the tar and rm entries
sudo gedit build build-konq

Manually extract the archives:
cd /opt/FriendlyARM/mini2440/
sudo chmod +x *.gz
sudo tar xfz qtopia-2.2.0.tar.gz
sudo tar xfz konq.tar.gz
sudo tar xfz fonts.tar.gz

Edit the following source files as indicated.
sudo gedit /opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/libraries/qtopia/qmemoryfile_unix.cpp line 141:  --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
line 141:  +++ f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

sudo gedit /opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qt2/src/tools/qmemoryfile_unix.cpp
line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

sudo gedit /opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/libraries/qtopia/backend/vobject.cpp
line 419: ---char *dot = strrchr(g,'.');
line 419: +++char *dot = (char *) strrchr(g,'.');

sudo gedit /opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/plugins/codecs/wavplugin/wavplugin.cpp
line 435: ---char *ext = strrchr( path.latin1(), '.' );
line 435: +++char *ext = (char *) strrchr( path.latin1(), '.' );

Grab ownership or else the install will fail...
sudo chown -R [youruser]:[yourgroup] /opt/FriendlyARM/

UPDATE: I've posted the build scripts I've used here.

run the build...
./build-all


Building an example (host)
Once the tools are in place, you can run a qt example and run it on the host.

Build the example:
cd /opt/FriendlyARM/mini2440/x86-qtopia/hello
./build

Change the last line of the run-hello script to find the hello executable:
sudo gedit run-hello
line 17: --- hello -qws
line 17: +++ /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/bin/hello -qws

./run-hello

At this point you should see the emulator display the hello example:


Building an example (arm)
Building the example for the embedded device is similar:

cd /opt/FriendlyARM/mini2440/arm-qtopia/hello
./build

Now move the binary to this folder so we can transfer it to the device (optional)
cp ../qtopia-2.2.0-FriendlyARM/qtopia/bin/hello .

To run this app on the 2440, first we have to move it there...

Moving the example app to the mini2440 (via ftp)
Since I'm running a linux vm under windows, I had to manually assign an ip address to my local area connection ( 192.168.1.120 ) via network connections.  Then I can ftp from the linux vm (which I set up to use NAT) to the 2440 via the crossover cable.

dev@ubuntu:/opt/friendlyARM/mini2440/arm-qtopia/hello$ ftp 192.168.1.230
Connected to 192.168.1.230.

200 PORT command successful.
150 Opening BINARY mode data connection for 'hello.desktop'.
226 Transfer complete.
97 bytes sent in 0.06 secs (1.7 kB/s)
ftp> quit

Running the app on the mini2440
In terminal on the 2440:
chmod +x hello
mv hello /opt/Qtopia/bin
mv hello.desktop /opt/Qtopia/apps/Applications

Reboot the MINI2440

Hello2440 should now appear in the Applications menu, where you can run it.

Where to go from here...
Along with the tooling you also installed the Qtopia documentation. To find the api docs, tutorials and lots of other information, point your browser here:

Qtopia docs:
file:///opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/doc/html/index.html

Qte docs:
file:///opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qt2/doc/html/index.html

Good luck 
Hope this guide is helpful and good luck with your own projects.

  2. I added it to the very end of the file.

    Alternatively, you can add it to the /etc/environment file editing the PATH entry to:

    PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/arm/4.3.2/bin"

  6. good work , better that official docs.

    I can compile leds in ubuntu 9.10 (I dislike RH too) but have troubles with I2c examples with a ton of errors.
    Is it because the libs that gcc tries to use and that are x86 instead of the one for mini2440 ?

    ReplyDelete
  7. Thanks for these instructions, very useful !

    Now, I'm trying to compile the examples included with QT Creator to make them work on the mini2440, but it don't work...

    Anyone know if is possible to compile a project created with Qt Creator to make it work on qtopia, on the mini2440 ??

    Thanks in advance !

  10. hi gopinath,

    I'm not sure I understand the question.

    Stephane,

    I believe you can use creator (the old version is installed along with x86qtopia) to generate the ui portion of the app. I didnt get anywhere with that though so I'm just use build scripts for the moment.

  25. Hi Everyone,

    I've added a post with all the build scripts I used for the tutorial.

    http://equallybad.blogspot.com/2010/04/x86-qtopia-and-arm-qtopia-build-scripts.html

    Let me know if these scripts help resolve any of the build issues.

    Good luck!

  31. Hi Jon, The package "uuid-dev" should install the libuuid library to /usr/lib/libuuid.so. Can you verify you have that installed? Also, which command are you executing?

    ReplyDelete
  32. Hi impossible

    The library /usr/lib/libuuid.so is not there.

    However I have installed it - yum install uuid-devel

    Package uuid-devel-1.6.1-8.fc12.i686 already installed and latest version

    I am running build-all from:
    /opt/FriendlyARM/mini2440/x86-qtopia/


    I imagine there is a issue with the missing libuuid.so file yet fedora knows its installed.

  33. SOLUTION

    Good news everybody!

    Thanks for Impossible for saying "The package "uuid-dev" should install the libuuid library to /usr/lib/libuuid.so"

    This was not the case. However after digging around I found that the library was in actual fact installed into /lib (Must have been Fedora 12 issue).

    TO SOLVE THIS:

    cd to /usr/lib and create a symbolic link using this command...

    ln -s ../../lib/libuuid.so.1 libuuid.so

    This library now should work. Run a make clean and ./build-all and your Qtopia installation should work.

    Well it did for me :).

  34. Hi Jon,

    Great find. Thanks for posting a solution.

  35. I think on the lines:
    line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
    line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

    You meant:

    line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
    line 143: +++ f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

    By the way, my version of the code has the following line:
    f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, 0777);

    You didn't say where to download the x86-qtopia, so I downloaded it from the http://www.friendlyarm.net website. I am going to presume that their version will not have the problems as you have stated and that 0777 will be the same as S_IRUSR|S_IWUSR. If not I will need to hunt down the root cause of the errors you were seeing to put in the correct fix for my version.

    ReplyDelete
  36. I downloaded arm-qtopia from http://www.microarmsystems.com. After extracting, the files were placed into /opt/FriendlyARM/mini2440/arm-qtopia, not the mini2440 directory. In this case I think the line of your instructions: cd /opt/FriendlyARM/mini2440/ would need to be changed to cd /opt/FriendlyARM/mini2440/arm-qtopia instead before manually extracting the files.

    ReplyDelete
  37. As it turned out the x86-qtopia I downloaded from http://www.friendlyarm.net worked fine with the 0777 in place of your S_IRUSR|S_IWUSR fix. Apparently they have updated their files- if that was your original source. Also I had trouble logging in as root. As I recall, you need to set up a root password before this can be used. Instead I logged in as plg with password plg. In my FriendlyARM terminal (minicom) I had to change the mode for the tmp directory to allow permissions from the ftp side to write the directory. The command I used was:
    cd /
    chmod o=rwx tmp

    ReplyDelete
  38. One more comment and I will be on my way. For those who may be confused by the phrase "In terminal on the 2440:". The best way to do this is as follows:
    Windows: Download Hyperterminal Private Edition
    Linux:
    1. Open a terminal window
    2. Enter cmd: sudo apt-get install minicom
    3. Enter cmd: sudo minicom -s
    4. Serial port setup
    +---------------------------------------+
    | A - Serial Device : dev/ttyS0 |
    | B - Lockfile Location : /var/lock |
    | C - ... |
    | D - ... |
    | E - Bps/Par/Bits : 115200 8N1 |
    | F - Hardware flow control : no |
    | G - Software flow control : no |
    | Change which settings? |
    +---------------------------------------+
    5. Exit
    6. Enter cmd "minicom"
    7. Attach the serial cable from your Mini2440 device to the serial port on your computer.
    8. Turn on the Mini2440 device.
    9. Press "enter" when directed to do so.
    If successfull you will get the following prompt:
    [root@FriendlyARM /]#
    Now you can navigate your FriendlyARM device from your Linux PC keyboard.

  41. Hi Anon,

    You have to install the software into the directory: /opt/FriendlyARM/mini2440

    and run the example from within the installed packages e.g. /opt/FriendlyARM/mini2440/x86qtopia

  45. Hello!

    Have you been able to write threaded applications with these tools? I've succesfully installed my tools according to your instructions and created a few applications. However, I can't compile threaded applications since I get an error that says:

    libqte-mt can't be found

    I've tried to configure qt2 again using -thread but I still won't succeed.

    Can you give me any advice?

  46. Hello,

    I've posted on friendlyarm forum as well but i can't solve this problem which Joe C., Jon Ambrose, Books and mr.Kolry encountered. Guess they solved, but i couldn't. I'm using ubuntu 10.04. I'm using the build* files as you described and followed your tutorial.

    I tried this soft link command but it's already linked. I mean;

    in /usr/lib i have;
    libuuid.so -> /lib/libuuid.so.1.3.0

    in /lib i have;
    libuuid.so.1.3.0
    libuuid.so.1 -> libuuid.so.1.3.0

    What can i do, i get the same error like others. Thanks.

    (Thanks for the tutorial as well...)

  49. Firstly, thanks for the great post!:) It worked perfectly for me, except the ending:

    (Building an example (host) part of the post)
    when I run the ./run-hello I get this instead of the output window
    shown:

    "Using display 0
    Cannot create lock file as an old version of QVFb has opened
    /tmp/qtembedded-root/QtEmbedded-0. Close other QVFb and try again
    Can't open framebuffer device /dev/fb0
    driver cannot connect"

    I have no idea what this is! I tried fuser -v /dev/fb0 but that didn't show
    anything, and "fuser -k -KILL /dev/fb0" didn't work either!

    Even running as root didn't work!

    Here is the output from the build: http://pastie.org/private/lgpty3p4y666xkm8gxcxcw

    Please do help me out! Thanks in advance!

    PS In case this matters, I'm running Ubuntu Lucid Lynx

  50. How do you create new UI forms? I was trying to use the current QT Creator but it makes version 4.0 ui files and I think this compiler needs version 2.2, right? Do I have to manually create XML files? Thanks. (I've been sort of following http://farm2440.blogspot.com/2010/07/hello-world-with-gui-application-for.html)

  51. Please disregard the previous post. I originally downloaded the QT Creator from http://qt.nokia.com/products/ but I've discovered the old Designer is already included in the qtopia-2.2.0-FriendlyARM/qt2/bin folder.

    Could you help me to solve it?

    Thank you in advance.

  53. to tsimur and others that have found the same problem: the trouble lies in some wrong reference to /usr/lib in a .la file, you can find info about this kind of problem at http://www.metastatic.org/text/libtool.html. I saw there is a new DVD but it takes 6 days to download, so...
    After a while (cursing someone's ancestors) I did this:
    - compile as much as you can, before the error
    - manually edit the file /opt/FriendlyARM/mini2440/arm-qtopia/konq/libtool
    - modify the line 6143 (sys_lib_search_path_spec="/lib /usr/lib /usr/local/lib"
    ) to sys_lib_search_path_spec=
    - build the hello sample
    It seems working

  56. Hello,

    First of all, my compliments for this great tutorial, I had it "up and running" in no time.
    (Ubuntu 10.04)

    I installed QTCreator via the available synaptic packages in this ubuntu release, but when I try to open hello_base.gui with QTdesigner, it gives me an error that it can't read the file. (tags with "name" on line 6 of this file doesn't seem to be OK)

    Is there something I need to configure within QTCreator/QTDesigner, or do I need another version of this tool ?
    (I'm using Qtopia 2.2.0)

    Thank you,

  68. Hi,
    Thanks for this tutorial. I need help with Touchscreen.
    I compiled Qt and tslib successfully.
    Typing "cat /dev/input/ts" works as mentioned (weird chars when touched).
    ts_calibrate and ts_test work fine too (touch screen is working fine).

    If I use "export QWS_MOUSE_PROTO=tslib:/dev/input/ts" it shows "Segmentation fault". When I replace this line by just "export QWS_MOUSE_PROTO=" (without "driver:options") my "Hello World" shows perfectly, but no touch screen.

    Compiling Qt with "-no-freetype" generates the same result: "Segmentation fault".

    I can't find a way to work touch with my app.

    Any suggestion?
