Issue with SensorTag application getting "stuck" after a reset

Other Parts Discussed in Thread: CC2650

Hello,

I’ve been battling an issue with the CC2650 SensorTag for the last couple days and wanted to see if someone had seen this before or has any input:

The issue that basically after a reset the Application gets stuck. I see the Red LED stay “on” on the HW and nothing else functions (advertising, events, etc). Here’s what’s odd:

  1. After programming my custom application (which is a modified SensorTag application) via CCS, and while still in debug mode, the code runs fine. Reset, restart, breakpoints, everything. After disconnecting the programmer and a power reset, the code does not run.
  2. If programming my HEX files with Flash Programmer 2, I see the Red LED come on right away
  3. Using TI’s original SensorTag source code, I compile and load the FW via CCS and the same issues as in #1 and #2 happen
  4. If I used the precompiled HEX in the Accessories folder, the SensorTag runs fine! 

My conclusion is that there is something in the SensorTag source code that is causing this issue. Memory overlap perhaps? Can anyone verify if they are seeing the same issue? Should I go back to Stack Rev 2.0?

Relevant information:

- SensorTag Rev 1.2

- Chip Rev 2.2

- Stack Rev 2.1

Looking forward to your input. I'm hoping it's some mismatch of version numbers that can be easily solved!

Thank you,
Nishant
