nrf9160 GPS problem

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.

  • Yes and AT client is not working. 

    If I switch the board name to nrf9160_pca10090, then compile it and run AT client example, then board only send

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

    but not responding to AT command.

    And if I switch the board name to nrf9160_pca10090ns (ns is non secure yes ?), then compile it and run debug, then MCU jump to EFFFFFFE memmory address and stay there. After MCU not responding and sending data.

    And this also happens for the nrf9160_pca10090ns and GPS example. What am I doing wrong ? Thank you.
