I am using STR9. While trying load the program to the flash
memory, I get the following error, 

 
In debug: &amp;quot;memory mismatch address 0x00000 value: 0xff extected
0x18&amp;quot; 
while downloading: &amp;quot;flash download failed could not stop ARM9E device

If automatic JTAG detection fails on STR9 then JTAG communication
is not working (manual settings will not help in this case and
debugging/flashing will still fail).&lt;/p&gt;

&lt;p&gt;
Check your HW and JTAG connection and try the following:&lt;br /&gt;
- reduce JTAG clock&lt;br /&gt;
- check also: &lt;a href="http://www.keil.com/support/docs/3215.htm"&gt;http://www.keil.com/support/docs/3215.htm&lt;/a&gt;&lt;/p&gt;

Yes I verified the algorithm. The microcontroller is STR912FAWX6,
and the algarithm is &amp;quot;ULINK arm debugger&amp;quot;. However, automatic device
chain initilization is failed. I manuelly add the device. If I choose
auto detection, it it says that &amp;quot;JTAG connection failed&amp;quot;.&lt;/p&gt;

&lt;p&gt;
When I press the load button, the device is resetted. But I get
the massage &amp;quot;flash download failed could not stop ARM9E device please
check the JTAG cable&amp;quot;&lt;/p&gt;

&lt;p&gt;
best regards&lt;/p&gt;

Ramazan&lt;/p&gt;

did you verify that the correct programming algorithm is
selected...?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
