A few days ago, I tried to use ulink pro+keil to test the code coverage of stm32f103, and I completed the task successfully. Now, I want to test the code coverage of TM4C123GH6PM. I enabled the clock of GPIOF, set the mode of PF1, PF2, PF3. When I started debug, the keil reported a error: Trace: Data stream error.
I edited the file Trace.ini and I set the debug option like this. What is the cause of this problem? How can I solve it?
