Tool/software: TI-RTOS
My question is about RTOS Analyzer -> Execution Graph. I have four tasks, two of them were hooked to functions, ConvertTemp(), LogTempDegC(), by using the app.cfg tool statically, the other two tasks, LoTaskFxn(), HiTaskFxn(), were created dynamically to experiment GateMutexPri usage, please refer to the attachment file for the two dynamically created tasks. The Expression window showed all the four tasks running normally. However, the HiTaskFxn task was not shown in the Execution Graph. Please advise how to make it visible in the Execution Graph.
