Running EnergyMicro Software on Linux

14 Apr 2013

As promised, here's a small video of the tool chain in action on Linux:

Used setup:

arm-none-eabi compiler chain
Files from EnergyMicro downloaded with Simplicity Studio; c code, CMSIS headers
Code::Blocks IDE, using files from energy micro
Programming through gdb is only possible when using the Segger JLink GDBServer. The gdbserver downloaded with Simplicity Studio will be able to debug, but can't program the EFM32GG990F1024 on the demo board
I set up code::blocks similar to the makefiles, the code::blocks project file is attached.

Big question to EFM32 experts: debugging current usage

When powering the EFM32 from the USB connector, I can monitor the current usage. When powering it from the energy harvesters, I can't. Anyone knows (not guesses, but knows) how the current measurement is performed? I guess I can find out by staring at schematics, application etcetera, but if any of the readers knows how it works, that could speed us all up quite a bit!

Cool video! The SWO output is only needed for the code trace, not the actual current measurement. If you want to hear a little more about how the power measurement work and energyAware Profiler you can check out this introduction: http://www.energymicro.com/lizard-labs/energyaware-profiler
