Asset_tracker with simulated GPS

[Ivan Loncar]

Hello, 

I have a problem building Asset tracker from SDK application example with simulated GPS data. After building an error message shows.

SPM and app are sharing an SPU region. Cannot partition flash correctly into secure and non-secure. Adjust partitions sizes so they are placed in separate regions.
region `FLASH' overflowed by 15872 bytes

I have selected simulated GPS on both spm_menucofing and in menuconfig.

Hi!

Do not disable simulated GPS in SPM, just in your non-secure application. Let me know if that solves this issue for you!

Best regards,

Heidi

The flash is overflowed again, I have tried the simulated GPS from .../nrf/samples/nrf9160/gps example where the flash is also overflowing when I use simulated GPS in just SPM. 

[Heidi]

Okay, I see. Which NCS version are you using? 

So you're building nrf9160/gps sample out of the box but adding CONFIG_GPS_SIM=y in the prj.conf file in the sample? And SPM is untouched, correct? 

[Ivan Loncar]

NCS v1.3.0 

No, I didn't add CONFIG_GPS_SIM=y. I opened in Segger Embedded Studio Project->Configure nRF connect SDK project and selected spm_menuconfig navigated to GPS drivers and checked GPS simulator and pressing configure. After i build the project I see that the FLASH has overflowed and that:

SPM and app are sharing an SPU region. Cannot partition flash correctly into secure and non-secure. Adjust partitions sizes so they are placed in separate regions.

I am reading this tab  (https://devzone.nordicsemi.com/f/nordic-q-a/50155/nrf9160-memory-partition )with memory partition problem to see if that helps. 

But I was hoping since it is an SDK version that it would work without me messing with partitioning etc.

Am I going in the right direction or os the problem in the beginning with how I try to enable GPS simulator in the first place?

P.S. True GPS readings with provided MOLEX GPS antenna are working in this example and I have no problems with it.

 Do not go into spm_menuconfig and enable GPS simulator. You only enable this in the menuconfig for your application.

[Ivan Loncar]

I was only going there in the hope it will work since when I enable simulated GPS trough menuconfig and look at what am I getting on the serial communication nothing happens. It is always searching a fix and that is it... What should I do to make the simulated GPS work? 

[Heidi]

Okay, so when you do it correctly you are able to build and flash the program to the device and then you get a new error, which is that you don't see any serial information from the device, correct? 

Then I will need to see the log file from the application? Are you using LTE Link Monitor? Are you using nRF9160 DK or Thingy:91?

[Ivan Loncar]

It isn't an error it just doesn't produce simulated GPS data it behaves the same when I use real GPS data. 

Yes, I am using the LTE link Monitor.

And I am using nrf9160 DK.

So I took a further look at the GPS simple and it doesn't look like this sample has support for using simulated GPS data, just by enabling this configuration. You will have to re-write the sample to use simulated GPS data. 

However, the asset tracker should have support for enabling simulated GPS. Just enable this config here.

Best regards,
