Hello, 

 
I&amp;#39;ve got a board with the AT91RM9200, where a u-boot bootloader is
installed. Now, I want to erase the external flash (SPI-Flash) where
the bootloader is installed to write my programm to the target
without a bootloader. But I always get</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: AT91RM9200: no jtag target found</title><link>https://community.arm.com/thread/130206?ContentTypeID=1</link><pubDate>Wed, 10 Oct 2007 03:14:17 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:4c72e0fa-71a9-40d6-9391-bc7f6a1b8c3b</guid><dc:creator>Tina Berger</dc:creator><description>&lt;p&gt;&lt;p&gt;
now I get the right connections for the jtag interface - it&amp;#39;s
almost the same connection of the ARM 20-Pin Connection (Ulink2).&lt;/p&gt;

&lt;p&gt;
So I use the 16-pin connector with the 20-pin ARM connector and
connect the first 16pins - but it doesn&amp;#39;t work....&lt;/p&gt;

&lt;p&gt;
The only difference is, that the 16-pin connector on the board has
no RTCK (AT91RM9200) and therefore the company has left this pin
unconnected...&lt;/p&gt;

&lt;p&gt;
I don&amp;#39;t know where could be the problem now... the JTAG speed is
100kHz, and I connect the jtag connector to the board and then I turn
of the voltage, so that the u-boot bootloader don&amp;#39;t start.&lt;/p&gt;

&lt;p&gt;
I hope anybody could help me with this problem&lt;/p&gt;

&lt;p&gt;
best wishes&lt;br /&gt;
Tina&lt;/p&gt;

&amp;gt;The left pin row is numbered 1-8, and the right pin &amp;gt;row is
numbered with even (sometimes colliding) &amp;gt;numbers...&lt;/p&gt;

&lt;p&gt;
right - I will call them tomorrow. But if you are right, and the
right pin row is GND, the left pin row is not suitable with the
ulink2, is it?&lt;/p&gt;

That is a very buggy JTAG description!&lt;/p&gt;

&lt;p&gt;
The left pin row is numbered 1-8, and the right pin row is
numbered with even (sometimes colliding) numbers...&lt;/p&gt;

&lt;p&gt;
I&amp;#39;m quite sure that the left pin row should be odd numbers, and
that all even numbers should be GND.&lt;/p&gt;

I read that in the datasheet of the board...&lt;/p&gt;

&lt;p&gt;
&lt;a href="http://www.taskit.de/ftp/manuals/Portux_TechnicalReference.pdf"&gt;www.taskit.de/.../Portux_TechnicalReference.pdf&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
Page23 is the pin assignment for the jtag interface... so I have
no chance to use this board together with my keil
&amp;Acirc;&amp;micro;vision edition 3? Do you know which jtag interface I
can use for this board?&lt;/p&gt;

&lt;p&gt;

Nine VCC and no GND???&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: AT91RM9200: no jtag target found</title><link>https://community.arm.com/thread/48730?ContentTypeID=1</link><pubDate>Mon, 08 Oct 2007 09:58:19 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:8942733c-7371-46ee-a426-2dc9ce0a7249</guid><dc:creator>Tina Berger</dc:creator><description>&lt;p&gt;&lt;p&gt;
could it be that the pin assignment of the jtag adapter is wrong
to use it together with the ulink?&lt;/p&gt;

&lt;p&gt;
Pin1 = VCC&lt;br /&gt;
Pin2 = VCC&lt;br /&gt;
Pin3 = NTRST&lt;br /&gt;
Pin4 = VCC&lt;br /&gt;
Pin5 = TDI&lt;br /&gt;
Pin6 = VCC&lt;br /&gt;
Pin7 = TMS&lt;br /&gt;
Pin8 = VCC&lt;br /&gt;
Pin9 = TCK&lt;br /&gt;
Pin10 = VCC&lt;br /&gt;
Pin11 = TCK&lt;br /&gt;
Pin12 = VCC&lt;br /&gt;
Pin13 = TDO&lt;br /&gt;
Pin14 = VCC&lt;br /&gt;
Pin15 = NRST&lt;br /&gt;
Pin16 = VCC&lt;/p&gt;
