Hi, 
I have board which contains Silabs 8051F060 MCU. It is working fine
when it is programmed with EC2 (RS232). It contains all protection
circuit on JTAG as suggested by Silabs like Schottky diode, series
resistors. 
When i try to connect this board</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Can't connect USB debug adapter</title><link>https://community.arm.com/thread/136093?ContentTypeID=1</link><pubDate>Mon, 15 Mar 2010 22:17:55 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:69bc45eb-cf3d-4328-b427-6a52c0bae936</guid><dc:creator>Sailesh Kumar</dc:creator><description>&lt;p&gt;&lt;p&gt;

HI,&lt;br /&gt;
Which .ini (initialization file) i have to select in &amp;quot;Debug&amp;quot; tab in
&amp;quot;Options for target&amp;quot; menu ?&lt;/p&gt;

&lt;p&gt;
I have selected &amp;quot;C:\SiLabs\MCU\USBXpress\Driver\setup.ini&amp;quot;.&lt;/p&gt;

&lt;p&gt;
Is it correct ?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Can't connect USB debug adapter</title><link>https://community.arm.com/thread/115599?ContentTypeID=1</link><pubDate>Fri, 12 Mar 2010 05:23:50 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:83b733f3-d6a9-449f-ad1f-c196f58180cb</guid><dc:creator>&amp;#178;erik malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
the IDE can not erase a protected chip. To erase a protected chip
you need to use the &amp;quot;Flash utilities&amp;quot;&lt;/p&gt;

&lt;p&gt;

Datasheet of C8051F060 says&lt;br /&gt;
&lt;i&gt;When the page containing the security bytes has been Write/Erase
locked, a JTAG full device erase&lt;br /&gt;
must be performed to unlock any areas of Flash protected by the
security bytes. A JTAG full&lt;br /&gt;
device erase is initiated by performing a normal JTAG erase operation
on either of the security byte&lt;br /&gt;
locations. This operation must be initiated through the JTAG port,
and cannot be performed from&lt;br /&gt;
firmware running on the device.&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
I have erased the flash with USB adapter.&lt;br /&gt;
But when try to connect for programming it shows error message (as
previous post).&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Can't connect USB debug adapter</title><link>https://community.arm.com/thread/90296?ContentTypeID=1</link><pubDate>Fri, 12 Mar 2010 02:17:12 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ed191196-e1a0-4b8c-8936-d11a6211b73f</guid><dc:creator>Tamir Michael</dc:creator><description>&lt;p&gt;&lt;p&gt;
Sounds like your CRP bit is enabled. I&amp;#39;d say you need to erase
your internal flash with a tool like FlashMagic (NXP) or via your own
internal bootloader/ISP.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Can't connect USB debug adapter</title><link>https://community.arm.com/thread/57888?ContentTypeID=1</link><pubDate>Fri, 12 Mar 2010 02:08:30 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:817d7c03-2bc7-4e61-b630-c4e7a71ffd56</guid><dc:creator>Sailesh Kumar</dc:creator><description>&lt;p&gt;&lt;p&gt;
