I&amp;#39;m new to RTX. Has anyone seen an example of how to run USB
device to SD memory card (I&amp;#39;m using MCB2300) under RTX? I see various
pieces but nothing whole. There&amp;#39;s an RTX demo with USB, but it uses a
dummy memory disk. There are good examples of USB</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: RTX with USB to SD</title><link>https://community.arm.com/thread/79885?ContentTypeID=1</link><pubDate>Fri, 06 Jan 2012 03:49:02 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:a653297f-9d47-4afb-b464-5dcb52479976</guid><dc:creator>David Russell</dc:creator><description>&lt;p&gt;&lt;p&gt;
Thanks guys, I had MDK 4.22 and that last example wasn&amp;#39;t in there.
It is exactly what I was looking for. You saved me a bunch of time
and frustration, now I can compare that example against what I did to
figure out what I did wrong. I appreciate it.&lt;/p&gt;

Look at the example:&lt;br /&gt;
\Keil\ARM\Boards\Keil\MCB2300\RL\USB\Device\RTX\Memory_FlashFS\SD_File&lt;/p&gt;

&lt;p&gt;
It should be exactly what you are looking for.&lt;/p&gt;

&lt;p&gt;
Note: MDK-ARM 4.23 is required&lt;/p&gt;

Doesn&amp;#39;t this example fit to your purpose?&lt;/p&gt;

&lt;p&gt;
C:\Keil\ARM\Boards\Keil\MCB2300\RL\USB_FlashFS\SD_File\&lt;/p&gt;

&lt;p&gt;

Just an update, I attached all of the files, libraries, and config
files as per the instructions, but in the instructions it then says
to call &amp;quot;init_card&amp;quot; which I think is out of date. Looking at the
RL/USB/DEVICE/MEMORY/SD_FILE/MEMORY example, the initialization of
the interface starts with:&lt;/p&gt;

&lt;p&gt;
mc0 = ioc_getcb (NULL); if (ioc_init (mc0) == 0) {&lt;/p&gt;

&lt;p&gt;
The first line seems to execute OK, but if the second line is
included, doesn&amp;#39;t even have to run, the code crashes, goes straight
to retartget.c _sys_exit&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
