Hi Juan,

Recent changes to the master branch has introduced breaking changes for using with Segger, where the board named for non-secure applications has changed to "nrf9160_pca10090ns". We are working on finding a solution for this issue.

At this time, you should use the command line in order to successfully compile.

Here's a quick method to use the command line for programming.

Linux/MacOS:

export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
export GNUARMEMB_TOOLCHAIN_PATH="/path/to/gcc-arm-none-eabi-Qx-2018/"
source /path/to/ncs/zephyr/zephyr-env.sh
cd /path/to/ncs/nrf/samples/nrf9160/myproject/
mkdir build && cd build
cmake .. -DBOARD=nrf9160_pca10090ns -GNinja
ninja flash

Windows:

set ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
set GNUARMEMB_TOOLCHAIN_PATH="c:\path\to\gcc-arm-none-eabi-Qx-2018"
c:\path\to\ncs\zephyr\zephyr-env.cmd
cd c:\path\to\ncs\nrf\samples\nrf9160\my_project\
mkdir build && cd build
cmake .. -DBOARD=nrf9160_pca10090ns -GNinja
ninja flash

Could you try this and see if that works better?

Kind regards,

Håkon

I cloned the latest repos today and noticed similar problems. However, I can't get it to work. I noticed that the areas being programmed by the sample applications do not line up with the non-secure flash memory regions:

asset_tracker with latest cloned repo:

Downloading ?zephyr.elf? to J-Link
Programming 140.2 KB of addresses 00000000 ? 00023103
Programming 2.9 KB of addresses 00023104 ? 00023caf

Is there a missing configuration?

Update.

I've changed printk in simple_at to printf and now it works.

Some tests I've done:

Erase memory
Flash secureboot
Flash functional firmware from the sdk (for example, asset tracker from sdk)
Flash simple_at firmware

Result==>it continues showing the output prints of the previous firmware.

Erase memory
Flash secure-boot

Result==>it continuously reboots

Erase memory
Flash secureboot
Flash simple_at firmware

Result==>it continuously reboots
