Troubleshooting
Here are some basic troubleshooting steps to help you fix issues you may encounter when using the Power
Profiler Kit (PPK).
My PPK desktop application won't start
Make sure the PPK board is powered and connected
to the computer.
Try running the desktop application from the
command line as described in
Profiler Kit desktop application
on page 21. Inspect
the error output.
You are most likely missing a SEGGER connection, or
the PPK has been flashed with the wrong firmware.
If upgrading has failed for some reason, run the
"recover_ppk.py" script in the software folder. This
should recover the board to the latest firmware.
I am only measuring noise
Make sure you have prepared the nRF5x DK for power
measurements by cutting the
SB9
as described in
Alternatively, check that the DUT select (
SW2
) switch
is in the correct position for your configuration.
My measurements fluctuate when I should have a
steady current draw
Your DUT may have a current consumption that is
close to a switching point causing rapid switching
up and down between the ranges and creating
measurement errors/distorted plots. Try adjusting the
switching points.
