Hi, 

 
I have upgraded my keil IDE:: LPC1800_DFP version from 2.6.0 to
2.7.0. my program is built with no error. Now i am trying to debug my
program using ULINK2. But i am not able to debug. it is always
showing error message.

Check SWD connectivity rather than JTAG&lt;br /&gt;
Check &amp;quot;Connect under Reset&amp;quot; options&lt;br /&gt;
Check the device is powered and connected properly, and you are not
running code that is breaking the debugger interface. ie
reconfiguring the pins it uses.&lt;/p&gt;

&lt;p&gt;
Check the availability of local training and support resources. ie
teachers, people you work with, people you went to school with,
etc.&lt;/p&gt;

This is a user forum, support has direct contact information.&lt;/p&gt;

&lt;p&gt;
Re-read the overview if this isn&amp;#39;t clear&lt;br /&gt;

Could someone tell how to fix?&lt;br /&gt;
Ant support from Keil is there or not?&lt;/p&gt;

Also note i am able to do Flash and erase.&lt;/p&gt;

&lt;p&gt;
Here i am getting 2 different error messages at different
scenario&lt;/p&gt;

&lt;p&gt;
scenario 1: once i loaded the program which is upgraded to 2.7.0,
then it is giving error message as &amp;quot;could not stop cortex M device,
please check the JTAG&amp;quot;&lt;/p&gt;

&lt;p&gt;
scenario 2: I tried first erasing the chip and trying to debug. On
that time i am getting error message as &amp;quot;CPU locked up stopping
target&amp;quot;&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
