I have a problem with Kinetis MKL24 based device.
It is powered with a single cell 3.0 V battery.
My software project is build with Processor Expert drivers, including MQX Lite OS driver.
I have a very simple single task that loops every 1 second and blinks some LED.
For some reason around 50% of cases when I insert battery into a socket my device does not start (no LED blinking).
I found that if I short-circuit GND with RESET pins on PCB's programming socket for a moment it starts do blink.
It also starts every time when started from under debugger.
Do you have any ideas what's the problem?
