Question:

 

How to set the JTAG TCLK Frequency?

 

 

 

 

Answer:

 

JTAG TCLK frequency can be set in CrossCore tool via JTAG Frequency Selection dialog box, it is used to test and set the frequency at which the test clock (TCK) runs in the debug perspective.

 

To access the JTAG Frequency Selection dialog box, choose Target > Settings > JTAG Frequency Selection, after launching a debug configuration,as documented in the help here: CCES>Help > Contents > CrossCore® Embedded Studio 2.8.0 > Integrated Development Environment > Debugging Targets > JTAG Frequency.

 

The blue arrow icon indicates the frequency at which the test clock is currently running. Note: For the ICE-2000 emulator, the arrow icon is not used.
