nRF9160 DK hardware exception

[Duy]

Dear Nordic Support,

When I got my nRF9160 DK, I ran the getting started successfully then I followed the instruction from the 2 below links:

https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/getting-started-with-nrf9160-dk

http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/getting_started.html

However, when I connected the board to Segger Embedded Studio, I selected "Erase All" before flashing the merged.hex file.

Then, I got the hardware exception error like the picture below:

I programmed the board with asset_tracker and at_client example and the error happened to both of them. I also selected nRF91 of SW5. I used Segger Embedded Studio to build, latest nrf-connect-sdk, PCA10090 version 0.8.3 and python 3.7.

Could you help me analyze the error, what are the causes and how can I fix it? 

Thank you and best regards,

Duy Tran

Hi,

Try to update to the latest modem fw version, found here: https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160/Download#infotabs

Thank you for your reply.

Yes, I did it after I uploaded the firmware but same error. 

And when I Erased All the nRF9160, I couldn't update the latest modem FW version.

If you were not able to flash the modem fw, then try to flash the at_client sample to the nRF9160, and then try to flash the modem fw again. And as Vish mentioned, please also use v0.4.0 tag.
