I am using KDS 3.0.0, KSDK 1.2.0 and OpenOCD connected to a FRDM-K64 board. TAD works with the hello_frdmk64f demo. While working through some of the lab exercises from this site to familiarize myself with the system and MQX, I found that TAD would not return data when the program was paused. I eventually traced the problem to the stack size declaration in the task setup. With a declared stack size of 900 or less for each task, it works, with a stack size of 1000 or greater, it doesn't. Is there something I have missed in the setup?
