I have a K64 project with multi-task using FreeRTOS, I noticed that some of tasks I can make BPs and step into it for debugging and MCUXpresso works properly, but some of the tasks I can make BP and the SW execution will stop at the BP but there is no any indication at all, so I am not able to do anything. I am using Tera Term to monitor system working condition so I know how the system is working.
If I suspend the program running (clicking the yellow double-bar button), I will get a warning of "Interrupt failed". At this point, if I click on Task List for Kernel Awareness, there is nothing come out. There is no interrupt handling in these tasks and it happens repeatably 100% even with single BP in the project.
