My nrf9160 which has the v1.0.0 modem and using v1.0.0 sdk has suddenly started continuouly resetting when i try to run asset tracker application.  I have tried at-command sample also and that gives an assertion Fail with bsdlib irrecoverable error: 3. I seem unable to program it with anything that works. I have programmed with programmer tool and from the command line using west. Any sugestions?

Hi,

 

We recently had a corner-case issue in nrfjprog v10.1.1 with nRF9160, where it did not properly run "--sectorerase", thus you needed to do a "nrfjprog -e" first.

What version of nrfjprog are you using?

 

Kind regards,

Håkon

nRfConnect v3.0.0

The first two writes were fine the last one nrfjprog --memwr 0x00FF8020 --val 0xFFFFFF20

gave

Parsing parameters.
ERROR: The area to write is not erased.

My board still continually resets although I'm not seeing the BSD error

Hi,

Can you check the contents of 0x00FF8020, with the command "nrfjprog --memrd 0x00FF8020 --n 4"?

0x00FF8020: FFFFFF20 | ...|

Hi,

That should be the correct value. (I.e. no reason to write it with the memwr command.)

If you go on to the next step, "reset with nrfjprog -r or on-board reset button", do you get things to work then?

If not, can you try again the steps for getting trace as described by Håkon Alseth?

After reset the board is still just constantly rebooting for asset tracker

For at command with modified config At commands still give errors.

here is a trace file but suspect it hasn't dtrace-2019-07-23T12-58-27.835Z.binone anything
