Hello,

I'm having a strange issue ... when I upgrade from firmware X to firmware Y, the MCU is consumming more amps (board consumption from 50mA to 80mA), and generates more heat (from 42°C to 50°C).

I checked a hundred time the differences in code, and cannot see any reason for this. Application is still running fine though ...

Any clue on how to debug this ? I'm using TASKING and I have ST Link V2 probes and SEGGER probes at hand.

Thomas.
