Do you have any examples of before and after readings that we can use as a basis for comparison?

You would see the power savings if you have a way of measuring the current from the 5V supply.

When I attempt to enable the Epiphany low power mode using the github version, I get the following error message:

sudo: bin/lowpower-mode.elf: command not found

If I use the version that was included in the default image, located in /home/linaro/Parallella/epiphany-examples/clockgating_mode, it works, as the necessary elf exists.

The following files exist in /home/linaro/Parallella/epiphany-examples/clockgating_mode/bin, but do not exist in the github version after running the build.sh script:

e-lowpower-mode.elf
e-lowpower-mode.srec
e_link_lowpower_mode.elf
e_link_lowpower_mode.srec
link_lowpower_mode.elf
lowpower-mode.elf

Obviously, I can used the provided version that was part of the default image, but I would like to get the github version working, as well. Also, once low power mode has been enabled, what is the best way to confirm that it is in fact enabled?
