This gist has patches to the Nordic PPK software to help it run under Linux.
Some other hints:
If you get whining about unable to find JLINKARM.dll, modify the
JLink.py file in pynrfjprog to set the DEFAULT_SEGGER_ROOT_PATH to
where you actually installed your JLink software:
pip show pynrfjprog
vi ~/.local/lib/python2.7/site-packages/pynrfjprog/JLink.py
For the non-responsive
plotting
issue you want 0001-ui-ppk_plotter-fix-starvation-on-Linux.patch

| Subject: [PATCH] ui/ppk_plotter: fix starvation on Linux | |
| Problem identification and general approach as in devzone topic below. | |
| Using a condvar made more sense to me, and this seems to work. | |
