issue: nRF9160 DK (PCA10090) is rebooting

Hi,


nRF9160 DK (PCA10090) is continuously rebooting.

I have flashed following Images and tested, but same issue (rebooting continuously) observed.


1. Pre-compiled Images provided from Nodric "">www.nordicsemi.com/.../Download"

[nRF9160 SiP application firmware ==> nrf9160dk_asset_tracker_09-10-2019_c9c833b1.hex] on nRF9160 DK using nRF connect V3.2.0 (Erase and & Write).

2. Compiled manually using SEGGER and command line (Power shell) the non-secure Image (nrf9160_pca10090ns)
and added the following in prj.conf

The sample is built as a non-secure firmware image

CONFIG_TRUSTED_EXECUTION_NONSECURE=y


#In this mode, the device sends GPS data every 2 seconds

CONFIG_POWER_OPTIMIZATION_ENABLE=n


CONFIG_AT_CMD_RESPONSE_MAX_LEN=3072


in these case, tried flashing "merged.hex" ==> Continuous rebooting

                                               "Zephyr.hex" ==> No response, No logs observed.


Please find the logs for the above cases:
