Simple AT doesn't seem to boot

[Diego García]

Hi!,

I'm trying to use simple_at program from https://github.com/Rallare/fw-nrfconnect-nrf2/tree/nrf9160_samples/samples/nrf9160/simple_at.

I erase all, then program secure_boot, then simple_at and reset, but it stops when showing "***** Booting Zephyr OS v1.13.99-ncs2 *****", and it doesn't show the first printk from app_socket_start nor accept AT commands (it always throws "timed out")

Any help?

Thanks!

Some tests I've done:

1. Erase memory
2. Flash secureboot
3. Flash functional firmware from the sdk (for example, asset tracker from sdk)
4. Flash simple_at firmware 

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

1. Erase memory
2. Flash secure-boot

Result==>it continuously reboots

1. Erase memory

3. Flash simple_at firmware

Update.

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

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:

Is there a missing configuration?

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
