Hi, 
I&amp;#39;ve been searching for two days now without any result so I post
this message and hope that someone could help me. 

 
I&amp;#39;m writing a program using ISR on the timer 0 and a button, on a
processor ARM9 from ST with their libraries.

Hi,&lt;br /&gt;
I finally found and resolve my problem :&lt;br /&gt;
The ST libraries are designed to fit with many compilators. But the
way those compilators indicate an ISR is different, for example in my
situation, the keil&amp;#39;s compilator needs the keyword &lt;b&gt;__irq&lt;/b&gt; in
the handler declaration.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
