Hi, can you provide a bit more details about how to program
Serial.c ? I dont even know how to make printf() works....&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Library Retarget File and Low Level I/O Routines</title><link>https://community.arm.com/thread/61680?ContentTypeID=1</link><pubDate>Tue, 19 Feb 2013 07:36:59 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:1609b591-4820-4e46-8030-ecae0b538d4b</guid><dc:creator>Dan Curran</dc:creator><description>&lt;p&gt;&lt;p&gt;
in these folders you will find a Retarget.c&lt;/p&gt;

&lt;p&gt;
C:\Keil\ARM\Boards\Freescale\TWR-K20D72M\RL\USB\Host\MSD_File&lt;/p&gt;

&lt;p&gt;
cant help you with your device as I am working on STM M3 devices
but I belive all hte retargets.c are the same&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
