I am having multiple random errors when trying to download/debug
using uVision4 and the ULink or ULink Pro JTAG units on a CortexM3
target. On good days, it actually programs flash and runs. That&amp;#39;s
very rare.

as far as the debugger locking up, unplugging the ulink2 from your
computer usually restores control.&lt;/p&gt;

&lt;p&gt;
Which device are you using?&lt;/p&gt;

&lt;p&gt;
Is this a custom board you are debugging on? Is the board showing
signs that it is running, or is it frozen.&lt;/p&gt;

&lt;p&gt;
If you go to project-&amp;gt; options for target -&amp;gt; Debug tab -&amp;gt;
Settings button (on the right hand side)&lt;/p&gt;

&lt;p&gt;
Can you see the ULINK serial number?&lt;/p&gt;

&lt;p&gt;
Can you see your device&amp;#39;s JTAG ID on the TDO row in on the right
hand side.&lt;/p&gt;

&lt;p&gt;
If this is a Cortex device, have you tried using serial wire
instead?&lt;/p&gt;

Hi Ken,&lt;/p&gt;

&lt;p&gt;
(Let me guess the LPC1788?)&lt;/p&gt;

&lt;p&gt;
I get these errors sometimes because the board is reset and there
is no code at 0x00. Or more precisely the reset vectors aren&amp;#39;t there
or are corrupted.&lt;/p&gt;

&lt;p&gt;
Generally what I do is erase the flash with flash magic
(&lt;a href="http://www.flashmagictool.com/"&gt;http://www.flashmagictool.com/&lt;/a&gt;)&lt;br /&gt;

and I&amp;#39;m back up and running.&lt;/p&gt;

&lt;p&gt;
Regards,&lt;/p&gt;

&lt;p&gt;
Marc&lt;/p&gt;
