Hi Keshav,

How about your issue? I test TI-RTOS code in MSP432P401 and do not found this problem you described.

Hi, Keshav!

We have encountered with the same problem. In our case, it was not related to code. Breakpoints in different tasks prevented the code from working correctly. Perhaps you have a similar problem.
