Hi, 
may a &amp;quot;long&amp;quot; going interrupt service routine crash the KEIL RTX? 

 
I currently porting a USB-CDC-Firmware to work with RTX and came
into trouble, but did not find the problem yet.

I found the problem(s):&lt;br /&gt;
- I used os_evt_send instead of isr_evt_send&lt;br /&gt;
- the task returned because of a break inside the invinite loop&lt;/p&gt;

&lt;p&gt;
Many thanks for all ideas and hints.&lt;/p&gt;

Possibly, you were just &amp;quot;on the edge&amp;quot; without RTX - and with it,
you are (just) over the edge?&lt;/p&gt;

&lt;p&gt;
Does the RTX &lt;b&gt;documentation&lt;/b&gt; state any limits on ISR
timings...?&lt;/p&gt;

But without RTX it does NOT crash...&lt;/p&gt;
