LAUNCHXL2-RM57L: Re: RM57L843: Values of global variables in watch expressions refreshing continuously problem

How to watch values of global variables in watch expressions refreshing continuously?

In the demo board and our project board, all values of the global variables in windows are all zero in real-time.

When I suspend the debug, the value can be seen. If resuming the debug, all the value are zero again.

Here I am using on board XDS110 USB Debug probe. CCS version is 10.2.

Above web shows my efforts and finding a method to solve the problem, but it impacts the interrupt servicing, any other suggestion?

Thank!!!

Has your program enabled the Cortex-R5F caches?

Yes, my program enabled the caches. All the program based on RM48, the expressions refreshing continuously very well.

I will have a try.

Thanks.

I have done the test. If cache is disabled at startup, all the value of global variables can be refreshed continuously.
