NRFUtil BLE DFU segmentation fault on OSX 10.15 / Python 3.7.1 / NRFUtil 6.0.0 / pc_ble_driver_py 0.14.0 / connectivity FW ?

[Otso Jousimaa]

Hello,

I'm trying to add DFU updates to a target board connected to a power profiler as a part of our CI process. 

I have a nRF52-DK programmed with connectivity firmware by nRF Connect for Desktop and I'm trying to use it via nrfutil to upload new firmware for power profiling and verifying that bootloader works. Here's my result:

(nrfutilenv) Otso-MacBook-Pro:src otsojousimaa$ nrfutil dfu ble -ic NRF52 -snr 682868184 -pkg targets/ruuvitag_b/armgcc/ruuvitag_b_armgcc_ruuvifw_default_v3.28.8_dfu_app.zip -f -n "Ruuvi"
Segmentation fault: 11
(nrfutilenv) Otso-MacBook-Pro:src otsojousimaa$ python --version
Python 3.7.1

Any idea on how to debug / fix / workaround this issue?

Hi,

nrfutil uses nrfjprog to flash the connectivity firmware to the DFU controller board when using option -f. Can you check if you get problems running other nrfjprog commands as well, e.g 'nrfjprog --eraseall'? If so please double check that you have installed the Jlink Software for macOS, which you can download from here.

Best regards,

Marjeris

Hi, 

I don't have a DK right now, but in general nrfjprog has worked without any issues.

(nrfutilenv) Otso-MacBook-Pro:src otsojousimaa$ nrfjprog --eraseall
ERROR: There is no debugger connected to the PC.

I'll check later today with the activated pyenv, but the issue seems to be something else as I still get the same segfault with nrfutil.

Just updating, this issue still persists on 6.0.1

Hi,

Sorry for the wait. I have been able to replicate the segmentation fault now. And I have forwarded the details of this crash to the team. I will let you know as soon as I have an update on this.
