Hello Tuan

Thanks. Which debug probe/prod are you using to connect. Please go through the following application report on using JTAG for TM4C devices.

Hello Amit,

Thank you very much. My problem is solved. I am using JTAG probe on section 4.6 from the document you gave me. And my problem is that I forgot connecting reset pin on Launchpad with reset pin on my tiva board!!!!

Thanks again,
Tuan
