CCS: ccs can't connect launchp tms320f28069m i use ccs7 and xds100v2

What is the state of the switches on S1?

From the FAQ section of the LAUNCHXL-F28069M Overview:

3. Why can’t I connect to the LaunchPad in Code Composer Studio?

There are a number of things that could cause this and they all have an easy fix.

• Is S1 switch 3 in the down position? This is the TRST pin that enables and disables JTAG functionality on the chip. This switch must be in the up position for the debug probe to be able to connect.

With S1 switch 3 in the down position I can repeat your error. With S1 switch 3 in the up (ON) position the CCS debugger can connect.
