Support for nrfutil as upload_protocol for zephyr framework

[LeoDJ]

Trying to upload any code built with the zephyr framework results in the following error: *** [upload] IndexError : list index out of range

Example platformio.ini:

[env:adafruit_feather_nrf52840]
platform = nordicnrf52
board = adafruit_feather_nrf52840
framework = zephyr

After digging around a bit in nordicnrf52/builder/main.py it seems to me that the nrfutil uploader is only available if you use the Arduino framework. But I want to be able to upload my existing code built with zephyr via nrfutil too.

*** [upload] IndexError : list index out of range

I'm not well versed in the platformio platform structure, so I can't easily implement that myself.

But I created the following workaround for now:

• Install nrfutil from pip (globally)
• Use the following options in platformio.ini:

  upload_protocol = custom
  upload_port = COM4
  upload_command = 
  nrfutil pkg generate --hw-version 52 --sd-req=0x00 --application $SOURCE --application-version 1 ${SOURCE}.zip 
  nrfutil dfu usb-serial -pkg ${SOURCE}.zip -p $UPLOAD_PORT

I am experiencing the same issue. Is there any official fix for it?

[pinsdorf]

I have the same issue when using an Adafruit Bluefruit nRF52832 board with Zephyr framework. The upload log also fails with *** [upload] IndexError : list index out of range. Platformio (5.1.1) and all packages are up-to-date. Is there any solution to this?

[rajithavk]

Simply add the upload_protocol toplatformio.ini for an example if you are using segger jlink,

upload_protocol = jlink

[LeoDJ]

@rajithavk no, I would still like to use nrfutil and if I put upload_protocol = nrfutil it'll behave the same way.
