nRF9160 DK flash of pre-compiled application doesn't work

Hello,

I got my hand on the nRF9160 DK 0.9.0 and was able to connect it correctly to the nRF connect cloud.

I followed the nRF Connect for Cloud Certificate Update and was able to update the certificate using at client application.

Then I tried to put back the asset tracker application (nrf9160dk_asset_tracker_2019-11-29_d3130d77.hex) from the following folder nrf9160dk_fw_2019-11-29_d3130d77 that I downloaded from the website qnd in the logs from LTE Link Monitor It seems that the board is reseting non stop. Below are the logs

Not sure what might went wrong in my set up!. I'm using nRF Connect Programmer to flash the hex file.

Any help would be much appreciated.

Thank you.

  • Any idea how I can fix this ? I tried again but with no luck ?

    I'm able to flash my thingy:91 successfully so I think the problem is deeper than me forgeting tiny simple thing in the process ?

  • Hey,

    can you try erasing the chip with "nrfjprog -e" before flashing?

  • I forget to update the modem firmware and this somehow caused this problem !

    is it normal to have this kind of issues ( software not even starting) because of the modem firmware ?
