Understood.

I am afraid that I do not have any ideas to why this is an issue or any possible solution. My suggestion is that you put a link to this question and a small decription of the issue in the comment section of the Eclipse Tutorial.

I've continued to use the no "Load Executable". If I re-enable it then the sd_softdevice_enable starts failing again. Let me know if there are any tests you want me to run.

@jcormier: I apologize for the late reply. I have not been able to reproduce this. Have you made any progress?

Note that this is running on Eclipse Mars on Ubuntu 16.04

@bjorn-spockeli. Agreed I found no mention of it myself, just stumbled upon it when i was trying to debug an already running unit... It seems odd though.

Hmm, cant find any reference to that in our tutorial, but I guess it will work if you manually flash the device before you start the debugging session.

I was just playing around with settings, and if I edit debug configurations, go to Startup tab, and uncheck "Load executable". sd_softdevice_enable now returns 0.

Yes the error code returned is 8 from sd_softdevice_enable().

Error code 8 is NRF_ERROR_INVALID_STATE Can you step into softdevice_handler_init in softdevice_handler.c and place a breakpoint after

err_code = sd_softdevice_enable(p_clock_lf_cfg, softdevice_fault_handler);

e.g. at if (err_code != NRF_SUCCESS), and check the error code to verify that this is the function that returns NRF_ERROR_INVALID_STATE.

Keep in mind that you cannot step through a sd_-call or after you have enabled the Softedevice as this vil halt the CPU and cause the SoftDevice to assert since this breaks its real-time requirements.
