nRF9160 SDK - PCA10090 (v0.7.0)

[David]

Hi,

Currently evaluating SDK and have some issues, I would like to run some demos.

I believe I've managed to erase the "preconfigured" Firmware on the SDK, I have tried to reprogram the nRF9160 with "nRF9160 DK board controller firmware".

Also, LED1 are not flashing when "power on", also see no activity with LED1 - 4.

Any suggestions??

With regards

David

It was technically answered by Bjorn with link2 (I believe).  I had the exact same problem.  You want to compile and load the Secure Boot project and program that as the MBR for the device.  I don't think they share this anywhere on the web you probably need to compile it yourself.  I tried to attach it to this message. 

It's in the GIT repo here: nrf\samples\nrf9160\secure_boot.  If you loaded the nRF Connect Getting Started app, you have to follow those directions and the arm cross compiler you need to get the slightly older version (you don't want Version 8-2018-q4, you want Version 7-2018-q2).  Then build it. 

After that you can install any other application and it should run.  The nRF connect programmer allows you to add multiple HEX files to program at once.

Almost a perfect answer! One quick comment though ;) You want to download version 7-2018-q2-update of the armemb toolchain from this link here. There is a bug with v8 that has already been reported & should hopefully be fixed soon.

Thanks!  Great catch, I didn't see that when I posted that.  I edited my post to make it a perfect answer.  ;)
