Sparkfun nRF52832

[sivi]

How to run the sdk examples from usb on the Sparkfun. I can run the adruino code, but want to shift to a more standard production environment. After manual install of GCC I can compile by "make" and when I run "make flush" get: make: *** No rule to make target `flush'. Stop.

How this can be solved. My main target now is to run the blinky example from MacOS usb to the sparkfun Breakout board. Very new to this. So maybe there is some basic misconception. Thanks for the helpers

You are trying to flash the application using nrfjprog. This is not the same as using nrfutil for updating the application using DFU. You need to create the DFU zip package and perform the DFU using nrfutil v0.5.2, as this is the last version supporting legacy DFU used by the bootloader on your board. You cannot use examples from SDK 14, as this will require updating the bootloader and softdevice, breaking the Arduino support.

I still recommend getting the development kit with the J-Link debugger, if you want to use examples from our SDK.
