Hi experts,

I ask this for my customer.

My customer is developing the AM2634 and they find the global variable can't be real-time continues fresh in expression window, it just change when the project stop to run.

And I enable the continues fresh and change the memory from cached to non cached, but it isn't work. Is any method to realize the real-time variable continues fresh in CCS?

Not in the way you might expect from other microcontrollers. My understanding is that this particular CPU participates in the JTAG memory access so you cannot monitor memory in this way with zero impact to program timing.

You can use the following techniques:

7.1. Debug Overview — Code Composer Studio 12.8.0 Documentation (Halt the debugger before any debugger access)

AM263x MCU+ SDK: Enabling Real Time Debug

The other option is to use the TRACE port but I think that is out of scope of the question.
