This service pack adds Power debugging capability, and corrects a number of problems in the 5.50.1 release. See the release notes for further details.

Power debugging is a methodology that provides software developers with information about how the software implementation in an embedded system affects system level power consumption. By coupling source code to power consumption, testing and tuning for power optimization is enabled. Power data can be visualized as a graph on a time scale or in the function profiler as energy consumption. The debugger supports power data from the following sources:

• J-Link Ultra
  Power data is measured with high accuracy at the board level.

• J-Link
  Power data is measured with low accuracy at the board level.

• The Energy Micro EFM32 Gecko kits
  A J-Link compatible debug probe is integrated on-board. Power data is measured with high accuracy at the MCU level.
