nrf9160 GPS problem

[MiroslavP]

Hello. I have problem with GPS example for nrf9160

I have:

Dev Board: PCA100900 0.8.5 2019.7

Source code: 

mcuboot: v1.3.99 aebd4b96d2abbeea5a3392c623369dd61ddf40cb 

nrf: v0.4.0 f9251026121264abc980a6c1e7928a802e8ab6e6

nrfxlib: v0.4.0 09bdd47ce20fd0ef0721eeb7c2eed10b5a199e0d

zephyr: v1.13.99 6c9637972f54e39640420c1e6ae096ac214c587c

Embedded  studio: 4.16

I'm use this firmware https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160/Download#infotabs

Build process will be fine for GPS sample code. But after uploading the source code to the MCU, I have this output on the UART interface.

The MCU does not send any additional data. He should send the GPS position. SIM card is insert on the slot.

[Hakon]

SIM card is insert on the slot.

 And you have registered the SIM card as well?

[MiroslavP]

Yes, SIM card is registered and working. I have two sim card, and SIM card is working on the different GSM module.

But why if I use nrf9160_pca10090ns and AT_Client example or others examples, then module jump to memmory address EFFFFFFE and stay here ? 

[MiroslavP]

Yes, flashing is correct. But thank you. I understand why code jump to the wrong  the memory address for non secure firmware.

But still AT_client doesn't work for me. Does not respond to any AT command, and on the serial console I have output "The AT host sample started" so, MCU is running. Only GSM modem not responding ? I do not know, but maybe I have bad firmware on the MCU ? I'm use firmware 0.7.0-29 alpha

I do not understand why modem not responding on the AT command.

[Hakon]

Try pushing the reset button and see what happens.

[MiroslavP]

MCU only send 

***** Booting Zephyr OS v1.14.99-ncs1 *****
The AT host sample started

and then does not respond to any AT command. This is for AT client sample. 

[Hakon]

Just make sure your at the right tag, by doing

cd ncs/nrf
git checkout master
git pull
git checkout v0.4.0
west update

Then run the following commands

nrfjprog -e

west build -b nrf9160_pca10090ns -d new_build123

west flash -d new_build123

from inside the at_client folder.

[MiroslavP]

I have problem with build.
