CCS/CC2640R2F: Can't Run Target CPU: (Error -2134 @ 0x0)

Hi,

Please check the section JTAG clock speed considerations of the XDS110 page below:

http://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_xds110.html

Given you are in the CCS Cloud environment, the changes shown there can only be applied by editing the XML code of the target configuration file.

Double-click on the target configuration file of your project:

Then, add the text below to the place indicated in the screenshot below:

ccxml said:

<property Type="choicelist" Value="1" id="The JTAG TCLK Frequency (MHz)">
<choice Name="Fixed with user specified value" value="SPECIFIC">
<property Type="stringfield" Value="2.5MHz" id="-- Enter a value from 100.0kHz to 2.5MHz"/>
</choice>
</property>

Save the file. You should be able to connect.  

Hope this helps,

Rafael
