NRF9160 Board for Qr Code Project: Merging Applications

[Gioele]

Hi!
I'm working on this particular project and the next step that I need to solve is connected to find a way to put in the same application the code of the GNSS example and the lpuart example. I understand that every application related to the modem can't work in the secure domain so I really need to run lpuart example in the non-secure domain and then I can proceed with the merging. The problem Is that when I try to run this lpuart example built on the non-secure domain, this doesn't run and a loop starts.

Hi Gioele

First, try to set the following configurations to get more debug information from your issue:

CONFIG_RESET_ON_FATAL_ERROR=n
CONFIG_LOG=y
CONFIG_THREAD_NAME=y

Also, are you able to use our lpuart sample with non-secure build out of the box?

Regards,
Sigurd Hellesvik

No, I can't.
But I find another solution that is the custom secure partition manager ( https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/using-a-custom-secure-partition-manager-wtih-your-application) the problem is that when I jump from the secure to non-secure applications all the data in the secure application are erased.

I tried building the lpuart sample for nrf9160dk_nrf9160_ns, and it works find.

I am using nRF Connect SDK v1.9.1. Which version are you using?

Hi!
Thanks for your reply, i try the lpuart sample with nRF Connect SDK v1.9.1. and now it works!
