Can't make flash.

[Jerome]

I've been trying to set up my nRF52 DK on my mac OS.

I followed all the steps to download the SDK (15.0.0), the Command Line Tools, the ARM GCC toolchain, and the J-Link Software and Documentation.

I even edited the path for the Makefile.posix

And set a $PATH for mergehex and nrfjprog.

I assume thats everything.

I plugged in the DK via USB and turned it on

I opened a terminal at armgcc folder in the blink example

Here is the result:

nrfjprog -f nrf52 --program _build/nrf52832_xxaa.hex --sectorerase
make: nrfjprog: No such file or directory
make: *** [flash] Error 1

Not really sure how to fix this.

I'm out of ideas on how to get it up and running. I just want to start programming.  Could really use the help.

Hi Jerome,

First I would like you to test your DK with a USB you are 100% sure that can transfer data.

I see that you are using the "Jaybird" cable which for my understanding is used to charge the "jaybird headset". (I think you have a "charge-only" cable)

Often such micro USB cables used to charge different products are missing the data lines, so they can only be used to power different devices.

So if you have a smartphone that uses a micro USB cable, they are more likely to have the data lines as well.

 

If that is not the case, I would suggest you to go through this list.
