<p>STM32f429 Discovery on ucLinux
Working the ucLinux get on easily the STM32f429 Doscpvery board. And making image can find github and clone your PC.</p>
<p>For running ucLinux on the STM32f429.</p>
<p>1 Host computer setup. <br />
My host computer is VM that is made VitrualBox.<br />
Host OS ubuntu 14.0.4LTS install to VM.</p>
<p>2 Host OS setup.<br />
Network configure on your environments.<br />
“git” install and setup.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ sudo apt-get update
$ sudo apt-get install git
</code></pre></div></div>
<p>If your environment use proxy when setup proxy environment.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ export http_proxy=http://&lt;&lt;PROXY HOST URL&gt;&gt;:&lt;&lt;PORT&gt;&gt;/
$ export ftp_proxy=http://&lt;&lt;PROXY HOST URL&gt;&gt;:&lt;&lt;PORT&gt;&gt;/
$ export https_proxy=http://&lt;&lt;PROXY HOST URL&gt;&gt;:&lt;&lt;PORT&gt;&gt;/
</code></pre></div></div>
<p>3 Install and Build OpenOCD<br />
OpenOCD needs several packages, so you can find and install them.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ sudo apt-get install libtool autoconf automake texinfo
$ sudo apt-get install libusb-dev libusb-1.0
</code></pre></div></div>
<p>OpenOCD download from the github.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ git clone http://git.code.sf.net/p/openocd/code
</code></pre></div></div>
<p>Build OpenOCD.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code> $ cd code
$ ./bootstrap
$ ./configure --prefix=/usr/local --enable-stlink
$ echo -e "all:\ninstall:" &gt; doc/Makefile
$ make
$ sudo make install
</code></pre></div></div>
<p>4 Installing Toolchain.<br />
Down load “arm-2010q1-189-arm-uclinuxeabi-i686-pc-linux-gnu.tar.bz2”<br />
The file exruct, made arm-2010q1 directory. Toolchain are under bin directory. So make path.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ export PATH=/home/XXXX/stm32/uclinux/arm-2010q1/bin:$PATH
</code></pre></div></div>
<p>In case of execute toolchain when fail commands.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ arm-uclinuxeabi-gcc
</code></pre></div></div>
<p>bash: /home/XXXX/stm32/uclinux/arm-2010q1/bin/arm-uclinuxeabi-gcc: No such file or directory</p>
<p>The toolchain commands are made by 32bit program, and need 32bit running environment.<br />
(My host OS is ubuntu 64bit)</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
</code></pre></div></div>
<p>If toolchain behave to below as OKAY.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ arm-uclinuxeabi-gcc
arm-uclinuxeabi-gcc: no input files
</code></pre></div></div>
<p>5 Install romfs</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ sudo apt-get install genromfs
</code></pre></div></div>
<p>6 stm32f429 linux download, build and install.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ git clone http://github.com/jserv/stm32f429-linux-builder
$ make
$ make install
</code></pre></div></div>
<p>7 But! I cant install!!<br />
Installing use STLink v2 that needs USB2.0, but VirtualBox has only USB1.0.<br />
VirtualBox add to USB2.0 function via extension pack.<br />
Latest VirtualBox version download and install, and more download extension pack. Olacles VirtualBox <a href="https://www.virtualbox.org/manual/ch01.html#intro-installing">here</a> .</p>
<p>And usb device is “root”</p>
<p>$ make install
libusb_open() failed with LIBUSB_ERROR_ACCESS</p>
<p>$ sudo make install</p>
<p>If you want to change kernel or busybox configuration when need ncurses for “make menuconfig”. Top level “make” using configuration files exists in ~/stm32f429-linux-builder/configs are busybox_config and kernel_config.</p>
<p>Running needs environment:</p>
<ul>
<li>STM32F429I-Discovery board</li>
<li>
<p>USB mini B(429) &lt;&gt; A(PC) for ST-Link</p>
</li>
<li>USB serial conversion cable, I bought that.
<ul>
<li>Txd and Rxd line cable.</li>
<li>Ex. serial connections.
<ul>
<li>STM32 PC11 &gt; Cable connector Orange Txd(PC)</li>
<li>STM32 PC10 &gt; Cable connector Yellow Rxd(PC)</li>

Welcome to Dungeon!
Dungeon is a game of adventure, danger, and low cunning. In it you will explore some of the most amazing territory ever seen by mortal man. Hardened adventurers have run screaming from the terrors contained within.
In Dungeon, the intrepid explorer delves into the forgotten secrets of a lost labyrinth deep in the bowels of the earth, searching for vast treasures long hidden from prying eyes, treasures guarded by fearsome monsters and diabolical traps!
No DECsystem should be without one!
Dungeon was created at the Programming Technology Division of the MIT Laboratory for Computer Science by Tim Anderson, Marc Blank, Bruce Daniels, and Dave Lebling. It was inspired by the Adventure game of Crowther and Woods, and the Dungeons and Dragons game of Gygax and Arneson. The original version was written in MDL (alias MUDDLE). The current version was translated from MDL into FORTRAN IV by a somewhat paranoid DEC engineer who prefers to remain anonymous, and was later translated to C.
On-line information may be obtained with the commands HELP and INFO.
